+
+Have a need for Bootstrap's brand resources? Great! We have only a few guidelines we follow, and in turn ask you to follow as well. These guidelines were inspired by MailChimp's [Brand Assets](https://mailchimp.com/about/brand-assets/).
+
+## Mark and logo
+
+Use either the Bootstrap mark (a capital **B**) or the standard logo (just **Bootstrap**). It should always appear in San Francisco Display Semibold. **Do not use the Twitter bird** in association with Bootstrap.
+

+
+## Name
+
+The project and framework should always be referred to as **Bootstrap**. No Twitter before it, no capital _s_, and no abbreviations except for one, a capital **B**.

+
+## Colors
+
+Our docs and branding use a handful of primary colors to differentiate what *is* Bootstrap from what *is in* Bootstrap. In other words, if it's purple, it's representative of Bootstrap.

+
+## Team
+
+Bootstrap is maintained by a [small team of developers](https://github.com/orgs/twbs/people) on GitHub. We're actively looking to grow this team and would love to hear from you if you're excited about CSS at scale, writing and maintaining vanilla JavaScript plugins, and improving build tooling processes for frontend code.
+
+## History
+
+Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.
+
+Bootstrap was created at Twitter in mid-2010 by [@mdo](https://twitter.com/mdo) and [@fat](https://twitter.com/fat). Prior to being an open-sourced framework, Bootstrap was known as _Twitter Blueprint_. A few months into development, Twitter held its [first Hack Week](https://blog.twitter.com/engineering/en_us/a/2010/hack-week.html) and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.
+
+Originally [released](https://blog.twitter.com/developer/en_us/a/2011/bootstrap-twitter.html) on <time datetime="2011-08-19 11:25">Friday, August 19, 2011</time>, we've since had over [twenty releases]({{< param repo >}}/releases), including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.
+
+With Bootstrap 4, we once again rewrote the project to account for two key architectural changes: a migration to Sass and the move to CSS's flexbox. Our intention is to help in a small way to move the web development community forward by pushing for newer CSS properties, fewer dependencies, and new technologies across more modern browsers.
+
+## Get involved

+description: Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.
+group: components
+aliases:
+  - "/components/"
+  - "/docs/4.6/components/"
+toc: true
+---
+
+## Examples
+
+Alerts are available for any length of text, as well as an optional dismiss button. For proper styling, use one of the eight **required** contextual classes (e.g., `.alert-success`). For inline dismissal, use the [alerts jQuery plugin](#dismissing).
+
+{{< example >}}
+{{< alerts.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="alert alert-{{ .name }}" role="alert">
+  A simple {{ .name }} alert—check it out!
+</div>{{- end -}}
+{{< /alerts.inline >}}
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+### Link color
+
+Use the `.alert-link` utility class to quickly provide matching colored links within any alert.
+
+{{< example >}}
+{{< alerts.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="alert alert-{{ .name }}" role="alert">
+  A simple {{ .name }} alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
+</div>{{ end -}}
+{{< /alerts.inline >}}
+{{< /example >}}
+
+### Additional content
+
+Alerts can also contain additional HTML elements like headings, paragraphs and dividers.
+
+{{< example >}}
+<div class="alert alert-success" role="alert">
+  <h4 class="alert-heading">Well done!</h4>
+  <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
+  <hr>
+  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
+</div>
+{{< /example >}}
+
+
+### Dismissing
+
+Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
+
+- Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript.
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}). The compiled version includes this.
+- Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
+- On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices.
+- To animate alerts when dismissing them, be sure to add the `.fade` and `.show` classes.
+
+You can see this in action with a live demo:
+
+{{< example >}}
+<div class="alert alert-warning alert-dismissible fade show" role="alert">
+  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
+  <button type="button" class="close" data-dismiss="alert" aria-label="Close">
+    <span aria-hidden="true">&times;</span>
+  </button>
+</div>
+{{< /example >}}
+
+## JavaScript behavior
+
+### Triggers
+
+Enable dismissal of an alert via JavaScript:
+
+```js
+$('.alert').alert()
+```
+
+Or with `data` attributes on a button **within the alert**, as demonstrated above:
+
+```html
+<button type="button" class="close" data-dismiss="alert" aria-label="Close">
+  <span aria-hidden="true">&times;</span>
+</button>
+```
+
+Note that closing an alert will remove it from the DOM.
+
+### Methods
+
+| Method | Description |
+| --- | --- |
+| `$().alert()` | Makes an alert listen for click events on descendant elements which have the `data-dismiss="alert"` attribute. (Not necessary when using the data-api's auto-initialization.) |
+| `$().alert('close')` | Closes an alert by removing it from the DOM. If the `.fade` and `.show` classes are present on the element, the alert will fade out before it is removed. |
+| `$().alert('dispose')` | Destroys an element's alert. |
+
+```js
+$('.alert').alert('close')
+```
+
+### Events
+
+Bootstrap's alert plugin exposes a few events for hooking into alert functionality.
+
+| Event | Description |
+| --- | --- |
+| `close.bs.alert` | This event fires immediately when the `close` instance method is called. |
+| `closed.bs.alert` | This event is fired when the alert has been closed (will wait for CSS transitions to complete). |
+
+```js
+$('#myAlert').on('closed.bs.alert', function () {
+  // do something...
+})
+```

+title: Badges
+description: Documentation and examples for badges, our small count and labeling component.
+group: components
+toc: true
+---
+
+## Example
+
+Badges scale to match the size of the immediate parent element by using relative font sizing and `em` units.
+
+{{< example >}}
+<h1>Example heading <span class="badge badge-secondary">New</span></h1>
+<h2>Example heading <span class="badge badge-secondary">New</span></h2>
+<h3>Example heading <span class="badge badge-secondary">New</span></h3>
+<h4>Example heading <span class="badge badge-secondary">New</span></h4>
+<h5>Example heading <span class="badge badge-secondary">New</span></h5>
+<h6>Example heading <span class="badge badge-secondary">New</span></h6>
+{{< /example >}}
+
+Badges can be used as part of links or buttons to provide a counter.
+
+{{< example >}}
+<button type="button" class="btn btn-primary">
+  Notifications <span class="badge badge-light">4</span>
+</button>
+{{< /example >}}
+
+Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.
+
+Unless the context is clear (as with the "Notifications" example, where it is understood that the "4" is the number of notifications), consider including additional context with a visually hidden piece of additional text.
+
+{{< example >}}
+<button type="button" class="btn btn-primary">
+  Profile <span class="badge badge-light">9</span>
+  <span class="sr-only">unread messages</span>
+</button>
+{{< /example >}}
+
+## Contextual variations
+
+Add any of the below mentioned modifier classes to change the appearance of a badge.
+
+{{< example >}}
+{{< badge.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<span class="badge badge-{{ .name }}">{{ .name | title }}</span>{{- end -}}
+{{< /badge.inline >}}
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+## Pill badges
+
+Use the `.badge-pill` modifier class to make badges more rounded (with a larger `border-radius` and additional horizontal `padding`). Useful if you miss the badges from v3.
+
+{{< example >}}
+{{< badge.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<span class="badge badge-pill badge-{{ .name }}">{{ .name | title }}</span>{{- end -}}
+{{< /badge.inline >}}
+{{< /example >}}
+
+## Links
+
+Using the contextual `.badge-*` classes on an `<a>` element quickly provide _actionable_ badges with hover and focus states.
+
+{{< example >}}
+{{< badge.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<a href="#" class="badge badge-{{ .name }}">{{ .name | title }}</a>{{- end -}}
+{{< /badge.inline >}}

+  </ol>
+</nav>
+{{< /example >}}
+
+## Changing the separator
+
+Separators are automatically added in CSS through [`::before`](https://developer.mozilla.org/en-US/docs/Web/CSS/::before) and [`content`](https://developer.mozilla.org/en-US/docs/Web/CSS/content). They can be changed by changing `$breadcrumb-divider`. The [quote](https://sass-lang.com/documentation/modules/string#quote) function is needed to generate the quotes around a string, so if you want `>` as separator, you can use this:
+
+```scss
+$breadcrumb-divider: quote(">");
+```
+
+It's also possible to use a **base64 embedded SVG icon**:
+
+```scss
+$breadcrumb-divider: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI4IiBoZWlnaHQ9IjgiPjxwYXRoIGQ9Ik0yLjUgMEwxIDEuNSAzLjUgNCAxIDYuNSAyLjUgOGw0LTQtNC00eiIgZmlsbD0iY3VycmVudENvbG9yIi8+PC9zdmc+);
+```
+
+The separator can be removed by setting `$breadcrumb-divider` to `none`:
+
+```scss
+$breadcrumb-divider: none;
+```
+
+## Accessibility
+
+Since breadcrumbs provide a navigation, it's a good idea to add a meaningful label such as `aria-label="breadcrumb"` to describe the type of navigation provided in the `<nav>` element, as well as applying an `aria-current="page"` to the last item of the set to indicate that it represents the current page.
+
+For more information, see the [WAI-ARIA Authoring Practices for the breadcrumb pattern](https://www.w3.org/TR/wai-aria-practices/#breadcrumb).

+title: Button group
+description: Group a series of buttons together on a single line with the button group, and super-power them with JavaScript.
+group: components
+toc: true
+---
+
+## Basic example
+
+Wrap a series of buttons with `.btn` in `.btn-group`. Add on optional JavaScript radio and checkbox style behavior with [our buttons plugin]({{< docsref "/components/buttons#button-plugin" >}}).
+
+{{< example >}}
+<div class="btn-group" role="group" aria-label="Basic example">
+  <button type="button" class="btn btn-secondary">Left</button>
+  <button type="button" class="btn btn-secondary">Middle</button>
+  <button type="button" class="btn btn-secondary">Right</button>
+</div>
+{{< /example >}}
+
+{{< callout warning >}}
+##### Ensure correct `role` and provide a label
+
+In order for assistive technologies (such as screen readers) to convey that a series of buttons is grouped, an appropriate `role` attribute needs to be provided. For button groups, this would be `role="group"`, while toolbars should have a `role="toolbar"`.
+
+In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use `aria-label`, but alternatives such as `aria-labelledby` can also be used.
+{{< /callout >}}
+
+## Button toolbar
+
+Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more.
+
+{{< example >}}
+<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
+  <div class="btn-group mr-2" role="group" aria-label="First group">
+    <button type="button" class="btn btn-secondary">1</button>
+    <button type="button" class="btn btn-secondary">2</button>
+    <button type="button" class="btn btn-secondary">3</button>
+    <button type="button" class="btn btn-secondary">4</button>
+  </div>
+  <div class="btn-group mr-2" role="group" aria-label="Second group">
+    <button type="button" class="btn btn-secondary">5</button>
+    <button type="button" class="btn btn-secondary">6</button>
+    <button type="button" class="btn btn-secondary">7</button>
+  </div>
+  <div class="btn-group" role="group" aria-label="Third group">
+    <button type="button" class="btn btn-secondary">8</button>
+  </div>
+</div>
+{{< /example >}}
+
+Feel free to mix input groups with button groups in your toolbars. Similar to the example above, you'll likely need some utilities though to space things properly.
+
+{{< example >}}
+<div class="btn-toolbar mb-3" role="toolbar" aria-label="Toolbar with button groups">
+  <div class="btn-group mr-2" role="group" aria-label="First group">
+    <button type="button" class="btn btn-secondary">1</button>
+    <button type="button" class="btn btn-secondary">2</button>
+    <button type="button" class="btn btn-secondary">3</button>
+    <button type="button" class="btn btn-secondary">4</button>
+  </div>
+  <div class="input-group">
+    <div class="input-group-prepend">
+      <div class="input-group-text" id="btnGroupAddon">@</div>
+    </div>
+    <input type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon">
+  </div>
+</div>
+
+<div class="btn-toolbar justify-content-between" role="toolbar" aria-label="Toolbar with button groups">
+  <div class="btn-group" role="group" aria-label="First group">
+    <button type="button" class="btn btn-secondary">1</button>
+    <button type="button" class="btn btn-secondary">2</button>
+    <button type="button" class="btn btn-secondary">3</button>
+    <button type="button" class="btn btn-secondary">4</button>
+  </div>
+  <div class="input-group">
+    <div class="input-group-prepend">
+      <div class="input-group-text" id="btnGroupAddon2">@</div>
+    </div>
+    <input type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon2">
+  </div>
+</div>
+{{< /example >}}
+
+## Sizing
+
+Instead of applying button sizing classes to every button in a group, just add `.btn-group-*` to each `.btn-group`, including each one when nesting multiple groups.
+
+<div class="bd-example">
+  <div class="btn-group btn-group-lg" role="group" aria-label="Large button group">
+    <button type="button" class="btn btn-secondary">Left</button>
+    <button type="button" class="btn btn-secondary">Middle</button>
+    <button type="button" class="btn btn-secondary">Right</button>
+  </div>
+  <br>
+  <div class="btn-group" role="group" aria-label="Default button group">
+    <button type="button" class="btn btn-secondary">Left</button>
+    <button type="button" class="btn btn-secondary">Middle</button>
+    <button type="button" class="btn btn-secondary">Right</button>
+  </div>
+  <br>
+  <div class="btn-group btn-group-sm" role="group" aria-label="Small button group">
+    <button type="button" class="btn btn-secondary">Left</button>
+    <button type="button" class="btn btn-secondary">Middle</button>
+    <button type="button" class="btn btn-secondary">Right</button>
+  </div>
+</div>
+
+```html
+<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
+<div class="btn-group" role="group" aria-label="...">...</div>
+<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>
+```
+
+## Nesting
+
+Place a `.btn-group` within another `.btn-group` when you want dropdown menus mixed with a series of buttons.
+
+{{< example >}}
+<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
+  <button type="button" class="btn btn-secondary">1</button>
+  <button type="button" class="btn btn-secondary">2</button>
+
+  <div class="btn-group" role="group">
+    <button id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+      Dropdown
+    </button>
+    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
+      <a class="dropdown-item" href="#">Dropdown link</a>
+      <a class="dropdown-item" href="#">Dropdown link</a>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+## Vertical variation
+
+Make a set of buttons appear vertically stacked rather than horizontally. **Split button dropdowns are not supported here.**
+
+<div class="bd-example">
+  <div class="btn-group-vertical" role="group" aria-label="Vertical button group">
+    <button type="button" class="btn btn-secondary">Button</button>
+    <button type="button" class="btn btn-secondary">Button</button>
+    <button type="button" class="btn btn-secondary">Button</button>
+    <button type="button" class="btn btn-secondary">Button</button>
+    <button type="button" class="btn btn-secondary">Button</button>

+title: Buttons
+description: Use Bootstrap's custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.
+group: components
+toc: true
+---
+
+## Examples
+
+Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.
+
+{{< example >}}
+{{< buttons.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<button type="button" class="btn btn-{{ .name }}">{{ .name | title }}</button>
+{{- end -}}
+{{< /buttons.inline >}}
+
+<button type="button" class="btn btn-link">Link</button>
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+## Disable text wrapping
+
+If you don't want the button text to wrap, you can add the `.text-nowrap` class to the button. In Sass, you can set `$btn-white-space: nowrap` to disable text wrapping for each button.
+
+## Button tags
+
+The `.btn` classes are designed to be used with the `<button>` element. However, you can also use these classes on `<a>` or `<input>` elements (though some browsers may apply a slightly different rendering).
+
+When using button classes on `<a>` elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a `role="button"` to appropriately convey their purpose to assistive technologies such as screen readers.
+
+{{< example >}}
+<a class="btn btn-primary" href="#" role="button">Link</a>
+<button class="btn btn-primary" type="submit">Button</button>
+<input class="btn btn-primary" type="button" value="Input">
+<input class="btn btn-primary" type="submit" value="Submit">
+<input class="btn btn-primary" type="reset" value="Reset">
+{{< /example >}}
+
+## Outline buttons
+
+In need of a button, but not the hefty background colors they bring? Replace the default modifier classes with the `.btn-outline-*` ones to remove all background images and colors on any button.
+
+{{< example >}}
+{{< buttons.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<button type="button" class="btn btn-outline-{{ .name }}">{{ .name | title }}</button>
+{{- end -}}
+{{< /buttons.inline >}}
+{{< /example >}}
+
+{{< callout info >}}
+Some of the button styles use a relatively light foreground color, and should only be used on a dark background in order to have sufficient contrast.
+{{< /callout >}}
+
+## Sizes
+
+Fancy larger or smaller buttons? Add `.btn-lg` or `.btn-sm` for additional sizes.
+
+{{< example >}}
+<button type="button" class="btn btn-primary btn-lg">Large button</button>
+<button type="button" class="btn btn-secondary btn-lg">Large button</button>
+{{< /example >}}
+
+{{< example >}}
+<button type="button" class="btn btn-primary btn-sm">Small button</button>
+<button type="button" class="btn btn-secondary btn-sm">Small button</button>
+{{< /example >}}
+
+Create block level buttons—those that span the full width of a parent—by adding `.btn-block`.
+
+{{< example >}}
+<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button>
+<button type="button" class="btn btn-secondary btn-lg btn-block">Block level button</button>
+{{< /example >}}
+
+## Active state
+
+Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. **There's no need to add a class to `<button>`s as they use a pseudo-class**. However, you can still force the same active appearance with `.active` (and include the <code>aria-pressed="true"</code> attribute) should you need to replicate the state programmatically.
+
+{{< example >}}
+<a href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary link</a>
+<a href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Link</a>
+{{< /example >}}
+
+## Disabled state
+
+Make buttons look inactive by adding the `disabled` boolean attribute to any `<button>` element.
+
+{{< example >}}
+<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
+<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>
+{{< /example >}}
+
+Disabled buttons using the `<a>` element behave a bit different:
+
+- `<a>`s don't support the `disabled` attribute, so you must add the `.disabled` class to make it visually appear disabled.
+- Some future-friendly styles are included to disable all `pointer-events` on anchor buttons. In browsers which support that property, you won't see the disabled cursor at all.
+- Disabled buttons should include the `aria-disabled="true"` attribute to indicate the state of the element to assistive technologies.
+
+{{< example >}}
+<a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary link</a>
+<a href="#" class="btn btn-secondary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>
+{{< /example >}}
+
+{{< callout warning >}}
+##### Link functionality caveat
+
+The `.disabled` class uses `pointer-events: none` to try to disable the link functionality of `<a>`s, but that CSS property is not yet standardized. In addition, even in browsers that do support `pointer-events: none`, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, add a `tabindex="-1"` attribute on these links (to prevent them from receiving keyboard focus) and use custom JavaScript to disable their functionality.
+{{< /callout >}}
+
+## Button plugin
+
+Do more with buttons. Control button states or create groups of buttons for more components like toolbars.
+
+### Toggle states
+
+Add `data-toggle="button"` to toggle a button's `active` state. If you're pre-toggling a button, you must manually add the `.active` class **and** `aria-pressed="true"` to the `<button>`.
+
+{{< example >}}
+<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false">
+  Single toggle
+</button>
+{{< /example >}}
+
+### Checkbox and radio buttons
+
+Bootstrap's `.button` styles can be applied to other elements, such as `<label>`s, to provide checkbox or radio style button toggling. Add `data-toggle="buttons"` to a `.btn-group` containing those modified buttons to enable their toggling behavior via JavaScript and add `.btn-group-toggle` to style the `<input>`s within your buttons. **Note that you can create single input-powered buttons or groups of them.**
+
+The checked state for these buttons is **only updated via `click` event** on the button. If you use another method to update the input—e.g., with `<input type="reset">` or by manually applying the input's `checked` property—you'll need to toggle `.active` on the `<label>` manually.
+
+Note that pre-checked buttons require you to manually add the `.active` class to the input's `<label>`.
+
+{{< example >}}
+<div class="btn-group-toggle" data-toggle="buttons">
+  <label class="btn btn-secondary active">
+    <input type="checkbox" checked> Checked
+  </label>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="btn-group btn-group-toggle" data-toggle="buttons">
+  <label class="btn btn-secondary active">
+    <input type="radio" name="options" id="option1" checked> Active
+  </label>
+  <label class="btn btn-secondary">
+    <input type="radio" name="options" id="option2"> Radio
+  </label>
+  <label class="btn btn-secondary">
+    <input type="radio" name="options" id="option3"> Radio
+  </label>
+</div>
+{{< /example >}}
+
+### Methods
+
+| Method | Description |
+| --- | --- |
+| `$().button('toggle')` | Toggles push state. Gives the button the appearance that it has been activated. |
+| `$().button('dispose')` | Destroys an element's button. |

+title: Cards
+description: Bootstrap's cards provide a flexible and extensible content container with multiple variants and options.
+group: components
+toc: true
+---
+
+## About
+
+A **card** is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. If you're familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.
+
+## Example
+
+Cards are built with as little markup and styles as possible, but still manage to deliver a ton of control and customization. Built with flexbox, they offer easy alignment and mix well with other Bootstrap components. They have no `margin` by default, so use [spacing utilities]({{< docsref "/utilities/spacing" >}}) as needed.
+
+Below is an example of a basic card with mixed content and a fixed width. Cards have no fixed width to start, so they'll naturally fill the full width of its parent element. This is easily customized with our various [sizing options](#sizing).
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+  <div class="card-body">
+    <h5 class="card-title">Card title</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+## Content types
+
+Cards support a wide variety of content, including images, text, list groups, links, and more. Below are examples of what's supported.
+
+### Body
+
+The building block of a card is the `.card-body`. Use it whenever you need a padded section within a card.
+
+{{< example >}}
+<div class="card">
+  <div class="card-body">
+    This is some text within a card body.
+  </div>
+</div>
+{{< /example >}}
+
+### Titles, text, and links
+
+Card titles are used by adding `.card-title` to a `<h*>` tag. In the same way, links are added and placed next to each other by adding `.card-link` to an `<a>` tag.
+
+Subtitles are used by adding a `.card-subtitle` to a `<h*>` tag. If the `.card-title` and the `.card-subtitle` items are placed in a `.card-body` item, the card title and subtitle are aligned nicely.
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  <div class="card-body">
+    <h5 class="card-title">Card title</h5>
+    <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+    <a href="#" class="card-link">Card link</a>
+    <a href="#" class="card-link">Another link</a>
+  </div>
+</div>
+{{< /example >}}
+
+### Images
+
+`.card-img-top` places an image to the top of the card. With `.card-text`, text can be added to the card. Text within `.card-text` can also be styled with the standard HTML tags.
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+  <div class="card-body">
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>
+{{< /example >}}
+
+### List groups
+
+Create lists of content in a card with a flush list group.
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  <ul class="list-group list-group-flush">
+    <li class="list-group-item">An item</li>
+    <li class="list-group-item">A second item</li>
+    <li class="list-group-item">A third item</li>
+  </ul>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  <div class="card-header">
+    Featured
+  </div>
+  <ul class="list-group list-group-flush">
+    <li class="list-group-item">An item</li>
+    <li class="list-group-item">A second item</li>
+    <li class="list-group-item">A third item</li>
+  </ul>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  <ul class="list-group list-group-flush">
+    <li class="list-group-item">An item</li>
+    <li class="list-group-item">A second item</li>
+    <li class="list-group-item">A third item</li>
+  </ul>
+  <div class="card-footer">
+    Card footer
+  </div>
+</div>
+{{< /example >}}
+
+### Kitchen sink
+
+Mix and match multiple content types to create the card you need, or throw everything in there. Shown below are image styles, blocks, text styles, and a list group—all wrapped in a fixed-width card.
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+  <div class="card-body">
+    <h5 class="card-title">Card title</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+  <ul class="list-group list-group-flush">
+    <li class="list-group-item">An item</li>
+    <li class="list-group-item">A second item</li>
+    <li class="list-group-item">A third item</li>
+  </ul>
+  <div class="card-body">
+    <a href="#" class="card-link">Card link</a>
+    <a href="#" class="card-link">Another link</a>
+  </div>
+</div>
+{{< /example >}}
+
+### Header and footer
+
+Add an optional header and/or footer within a card.
+
+{{< example >}}
+<div class="card">
+  <div class="card-header">
+    Featured
+  </div>
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+Card headers can be styled by adding `.card-header` to `<h*>` elements.
+
+{{< example >}}
+<div class="card">
+  <h5 class="card-header">Featured</h5>
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="card">
+  <div class="card-header">
+    Quote
+  </div>
+  <div class="card-body">
+    <blockquote class="blockquote mb-0">
+      <p>A well-known quote, contained in a blockquote element.</p>
+      <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
+    </blockquote>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="card text-center">
+  <div class="card-header">
+    Featured
+  </div>
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+  <div class="card-footer text-muted">
+    2 days ago
+  </div>
+</div>
+{{< /example >}}
+
+## Sizing
+
+Cards assume no specific `width` to start, so they'll be 100% wide unless otherwise stated. You can change this as needed with custom CSS, grid classes, grid Sass mixins, or utilities.
+
+### Using grid markup
+
+Using the grid, wrap cards in columns and rows as needed.
+
+{{< example >}}
+<div class="row">
+  <div class="col-sm-6">
+    <div class="card">
+      <div class="card-body">
+        <h5 class="card-title">Special title treatment</h5>
+        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+        <a href="#" class="btn btn-primary">Go somewhere</a>
+      </div>
+    </div>
+  </div>
+  <div class="col-sm-6">
+    <div class="card">
+      <div class="card-body">
+        <h5 class="card-title">Special title treatment</h5>
+        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+        <a href="#" class="btn btn-primary">Go somewhere</a>
+      </div>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### Using utilities
+
+Use our handful of [available sizing utilities]({{< docsref "/utilities/sizing" >}}) to quickly set a card's width.
+
+{{< example >}}
+<div class="card w-75">
+  <div class="card-body">
+    <h5 class="card-title">Card title</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Button</a>
+  </div>
+</div>
+
+<div class="card w-50">
+  <div class="card-body">
+    <h5 class="card-title">Card title</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Button</a>
+  </div>
+</div>
+{{< /example >}}
+
+### Using custom CSS
+
+Use custom CSS in your stylesheets or as inline styles to set a width.
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+## Text alignment
+
+You can quickly change the text alignment of any card—in its entirety or specific parts—with our [text align classes]({{< docsref "/utilities/text#text-alignment" >}}).
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+
+<div class="card text-center" style="width: 18rem;">
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+
+<div class="card text-right" style="width: 18rem;">
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+## Navigation
+
+Add some navigation to a card's header (or block) with Bootstrap's [nav components]({{< docsref "/components/navs" >}}).
+
+{{< example >}}
+<div class="card text-center">
+  <div class="card-header">
+    <ul class="nav nav-tabs card-header-tabs">
+      <li class="nav-item">
+        <a class="nav-link active" href="#">Active</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+  </div>
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="card text-center">
+  <div class="card-header">
+    <ul class="nav nav-pills card-header-pills">
+      <li class="nav-item">
+        <a class="nav-link active" href="#">Active</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+  </div>
+  <div class="card-body">
+    <h5 class="card-title">Special title treatment</h5>
+    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+    <a href="#" class="btn btn-primary">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+## Images
+
+Cards include a few options for working with images. Choose from appending "image caps" at either end of a card, overlaying images with card content, or simply embedding the image in a card.
+
+### Image caps
+
+Similar to headers and footers, cards can include top and bottom "image caps"—images at the top or bottom of a card.
+
+{{< example >}}
+<div class="card mb-3">

+</div>
+{{< /example >}}
+
+### Image overlays
+
+Turn an image into a card background and overlay your card's text. Depending on the image, you may or may not need additional styles or utilities.
+
+{{< example >}}
+<div class="card bg-dark text-white">
+  {{< placeholder width="100%" height="270" class="bd-placeholder-img-lg card-img" text="Card image" >}}
+  <div class="card-img-overlay">
+    <h5 class="card-title">Card title</h5>
+    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+    <p class="card-text">Last updated 3 mins ago</p>
+  </div>
+</div>
+{{< /example >}}
+
+{{< callout info >}}
+Note that content should not be larger than the height of the image. If content is larger than the image the content will be displayed outside the image.
+{{< /callout >}}
+
+## Horizontal
+
+Using a combination of grid and utility classes, cards can be made horizontal in a mobile-friendly and responsive way. In the example below, we remove the grid gutters with `.no-gutters` and use `.col-md-*` classes to make the card horizontal at the `md` breakpoint. Further adjustments may be needed depending on your card content.
+
+{{< example >}}
+<div class="card mb-3" style="max-width: 540px;">
+  <div class="row no-gutters">
+    <div class="col-md-4">
+      {{< placeholder width="100%" height="250" class="" text="Image" >}}
+    </div>
+    <div class="col-md-8">
+      <div class="card-body">
+        <h5 class="card-title">Card title</h5>
+        <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+        <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+      </div>
+    </div>
+  </div>
+</div>

+
+## Card styles
+
+Cards include various options for customizing their backgrounds, borders, and color.
+
+### Background and color
+
+Use [text and background utilities]({{< docsref "/utilities/colors" >}}) to change the appearance of a card.
+
+{{< example >}}
+{{< card.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="card{{ if not (eq .name "light") }} text-white{{ end }} bg-{{ .name }} mb-3" style="max-width: 18rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body">
+    <h5 class="card-title">{{ .name | title }} card title</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>
+{{- end -}}
+{{< /card.inline >}}
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+### Border
+
+Use [border utilities]({{< docsref "/utilities/borders" >}}) to change just the `border-color` of a card. Note that you can put `.text-{color}` classes on the parent `.card` or a subset of the card's contents as shown below.
+
+{{< example >}}
+{{< card.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="card border-{{ .name }} mb-3" style="max-width: 18rem;">
+  <div class="card-header">Header</div>
+  <div class="card-body{{ if not (eq .name "light") }} text-{{ .name }}{{ end }}">
+    <h5 class="card-title">{{ .name | title }} card title</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+</div>
+{{- end -}}
+{{< /card.inline >}}
+{{< /example >}}
+
+### Mixins utilities
+
+You can also change the borders on the card header and footer as needed, and even remove their `background-color` with `.bg-transparent`.
+
+{{< example >}}
+<div class="card border-success mb-3" style="max-width: 18rem;">
+  <div class="card-header bg-transparent border-success">Header</div>
+  <div class="card-body text-success">
+    <h5 class="card-title">Success card title</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+  </div>
+  <div class="card-footer bg-transparent border-success">Footer</div>
+</div>
+{{< /example >}}
+
+## Card layout
+
+In addition to styling the content within cards, Bootstrap includes a few options for laying out series of cards. For the time being, **these layout options are not yet responsive**.
+
+### Card groups
+
+Use card groups to render cards as a single, attached element with equal width and height columns. Card groups start off stacked and use `display: flex;` to become attached with uniform dimensions starting at the `sm` breakpoint.
+
+{{< example >}}
+<div class="card-group">
+  <div class="card">
+    {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">
+      <h5 class="card-title">Card title</h5>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+    </div>
+  </div>
+  <div class="card">
+    {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">
+      <h5 class="card-title">Card title</h5>
+      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
+      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+    </div>
+  </div>
+  <div class="card">
+    {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">
+      <h5 class="card-title">Card title</h5>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
+      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+When using card groups with footers, their content will automatically line up.
+
+{{< example >}}
+<div class="card-group">
+  <div class="card">
+    {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">
+      <h5 class="card-title">Card title</h5>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
+    </div>
+    <div class="card-footer">
+      <small class="text-muted">Last updated 3 mins ago</small>
+    </div>
+  </div>
+  <div class="card">
+    {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">
+      <h5 class="card-title">Card title</h5>
+      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
+    </div>
+    <div class="card-footer">

+    </div>
+  </div>
+  <div class="card">
+    {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">
+      <h5 class="card-title">Card title</h5>
+      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
+    </div>
+    <div class="card-footer">
+      <small class="text-muted">Last updated 3 mins ago</small>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### Card decks
+
+Need a set of equal width and height cards that aren't attached to one another? Use card decks.
+
+{{< example >}}
+<div class="card-deck">
+  <div class="card">
+    {{< placeholder width="100%" height="200" class="card-img-top" text="Image cap" >}}
+    <div class="card-body">

+
+### Grid cards
+
+Use the Bootstrap grid system and its [`.row-cols` classes]({{< docsref "/layout/grid#row-columns" >}}) to control how many grid columns (wrapped around your cards) you show per row. For example, here's `.row-cols-1` laying out the cards on one column, and `.row-cols-md-2` splitting four cards to equal width across multiple rows, from the medium breakpoint up.
+
+{{< example >}}
+<div class="row row-cols-1 row-cols-md-2">
+  <div class="col mb-4">
+    <div class="card">
+      {{< placeholder width="100%" height="180" class="card-img-top" text="Image cap" >}}
+      <div class="card-body">

+        <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>

+### Card columns
+
+Cards can be organized into [Masonry](https://masonry.desandro.com/)-like columns with just CSS by wrapping them in `.card-columns`. Cards are built with CSS `column` properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to right.
+
+**Heads up!** Your mileage with card columns may vary. To prevent cards breaking across columns, we must set them to `display: inline-block` as `column-break-inside: avoid` isn't a bulletproof solution yet.
+
+{{< example >}}
+<div class="card-columns">
+  <div class="card">
+    {{< placeholder width="100%" height="160" class="card-img-top" text="Image cap" >}}

+
+Card columns can also be extended and customized with some additional code. Shown below is an extension of the `.card-columns` class using the same CSS we use—CSS columns— to generate a set of responsive tiers for changing the number of columns.
+
+```scss
+.card-columns {
+  @include media-breakpoint-only(lg) {
+    column-count: 4;
+  }
+  @include media-breakpoint-only(xl) {
+    column-count: 5;
+  }

+title: Carousel
+description: A slideshow component for cycling through elements—images or slides of text—like a carousel.
+group: components
+toc: true
+---
+
+## How it works
+
+The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms and a bit of JavaScript. It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators.
+
+In browsers where the [Page Visibility API](https://www.w3.org/TR/page-visibility/) is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.).
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards.
+
+Lastly, if you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+
+## Example
+
+Carousels don't automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they're not explicitly required. Add and customize as you see fit.
+
+**The `.active` class needs to be added to one of the slides** otherwise the carousel will not be visible. Also be sure to set a unique id on the `.carousel` for optional controls, especially if you're using multiple carousels on a single page. Control and indicator elements must have a `data-target` attribute (or `href` for links) that matches the id of the `.carousel` element.
+
+### Slides only
+
+Here's a carousel with slides only. Note the presence of the `.d-block` and `.w-100` on carousel images to prevent browser default image alignment.
+
+{{< example >}}
+<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+        {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### With controls
+
+Adding in the previous and next controls:
+
+{{< example >}}
+<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{{< /example >}}
+
+### With indicators
+
+You can also add the indicators to the carousel, alongside the controls, too.
+
+{{< example >}}
+<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
+  <ol class="carousel-indicators">
+    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
+    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
+    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
+  </ol>
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{{< /example >}}
+
+### With captions
+
+Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`. They can be easily hidden on smaller viewports, as shown below, with optional [display utilities]({{< docsref "/utilities/display" >}}). We hide them initially with `.d-none` and bring them back on medium-sized devices with `.d-md-block`.
+
+{{< example >}}
+<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel">
+  <ol class="carousel-indicators">
+    <li data-target="#carouselExampleCaptions" data-slide-to="0" class="active"></li>
+    <li data-target="#carouselExampleCaptions" data-slide-to="1"></li>
+    <li data-target="#carouselExampleCaptions" data-slide-to="2"></li>
+  </ol>
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+      <div class="carousel-caption d-none d-md-block">
+        <h5>First slide label</h5>
+        <p>Some representative placeholder content for the first slide.</p>
+      </div>
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+      <div class="carousel-caption d-none d-md-block">
+        <h5>Second slide label</h5>
+        <p>Some representative placeholder content for the second slide.</p>
+      </div>
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+      <div class="carousel-caption d-none d-md-block">
+        <h5>Third slide label</h5>
+        <p>Some representative placeholder content for the third slide.</p>
+      </div>
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleCaptions" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleCaptions" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{{< /example >}}
+
+### Crossfade
+
+Add `.carousel-fade` to your carousel to animate slides with a fade transition instead of a slide.
+
+{{< example >}}
+<div id="carouselExampleFade" class="carousel slide carousel-fade" data-ride="carousel">
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleFade" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleFade" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{{< /example >}}
+
+### Individual `.carousel-item` interval
+
+Add `data-interval=""` to a `.carousel-item` to change the amount of time to delay between automatically cycling to the next item.
+
+{{< example >}}
+<div id="carouselExampleInterval" class="carousel slide" data-ride="carousel">
+  <div class="carousel-inner">
+    <div class="carousel-item active" data-interval="10000">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+    </div>
+    <div class="carousel-item" data-interval="2000">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleInterval" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleInterval" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{{< /example >}}
+
+### Disable touch swiping
+
+Carousels support swiping left/right on touchscreen devices to move between slides. This can be disabled using the `data-touch` attribute. The example below also does not include the `data-ride` attribute and has `data-interval="false"` so it doesn't autoplay.
+
+{{< example >}}
+<div id="carouselExampleControlsNoTouching" class="carousel slide" data-touch="false" data-interval="false">
+  <div class="carousel-inner">
+    <div class="carousel-item active">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
+    </div>
+    <div class="carousel-item">
+      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
+    </div>
+  </div>
+  <a class="carousel-control-prev" href="#carouselExampleControlsNoTouching" role="button" data-slide="prev">
+    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
+    <span class="sr-only">Previous</span>
+  </a>
+  <a class="carousel-control-next" href="#carouselExampleControlsNoTouching" role="button" data-slide="next">
+    <span class="carousel-control-next-icon" aria-hidden="true"></span>
+    <span class="sr-only">Next</span>
+  </a>
+</div>
+{{< /example >}}
+
+## Usage
+
+### Via data attributes
+
+Use data attributes to easily control the position of the carousel. `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`.
+
+The `data-ride="carousel"` attribute is used to mark a carousel as animating starting at page load. If you don't use `data-ride="carousel"` to initialize your carousel, you have to initialize it yourself. **It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.**
+
+### Via JavaScript
+
+Call carousel manually with:
+
+```js
+$('.carousel').carousel()
+```
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.

+
+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### `.carousel(options)`
+
+Initializes the carousel with an optional options `object` and starts cycling through items.
+
+```js
+$('.carousel').carousel({
+  interval: 2000
+})
+```
+
+#### `.carousel('cycle')`
+
+Cycles through the carousel items from left to right.
+
+#### `.carousel('pause')`
+
+Stops the carousel from cycling through items.
+
+#### `.carousel(number)`
+
+Cycles the carousel to a particular frame (0 based, similar to an array). **Returns to the caller before the target item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+#### `.carousel('prev')`
+
+Cycles to the previous item. **Returns to the caller before the previous item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+#### `.carousel('next')`
+
+Cycles to the next item. **Returns to the caller before the next item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+#### `.carousel('dispose')`
+
+Destroys an element's carousel.
+
+#### `.carousel('nextWhenVisible')`
+
+Don't cycle the carousel to next when the page isn't visible or the carousel or its parent isn't visible. **Returns to the caller before the next item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+#### `.carousel('to')`
+
+Cycles the carousel to a particular frame (0 based, similar to an array). **Returns to the caller before the next item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
+
+### Events
+
+Bootstrap's carousel class exposes two events for hooking into carousel functionality. Both events have the following additional properties:
+
+- `direction`: The direction in which the carousel is sliding (either `"left"` or `"right"`).
+- `relatedTarget`: The DOM element that is being slid into place as the active item.
+- `from`: The index of the current item
+- `to`: The index of the next item
+
+All carousel events are fired at the carousel itself (i.e. at the `<div class="carousel">`).
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 150px;">Event Type</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>slide.bs.carousel</td>
+      <td>This event fires immediately when the <code>slide</code> instance method is invoked.</td>
+    </tr>
+    <tr>
+      <td>slid.bs.carousel</td>
+      <td>This event is fired when the carousel has completed its slide transition.</td>
+    </tr>
+  </tbody>
+</table>
+
+```js
+$('#myCarousel').on('slide.bs.carousel', function () {
+  // do something...
+})
+```
+
+### Change transition duration
+
+The transition duration of `.carousel-item` can be changed with the `$carousel-transition` Sass variable before compiling or custom styles if you're using the compiled CSS. If multiple transitions are applied, make sure the transform transition is defined first (eg. `transition: transform 2s ease, opacity .5s ease-out`).

+title: Collapse
+description: Toggle the visibility of content across your project with a few classes and our JavaScript plugins.
+group: components
+toc: true
+---
+
+## How it works
+
+The collapse JavaScript plugin is used to show and hide content. Buttons or anchors are used as triggers that are mapped to specific elements you toggle. Collapsing an element will animate the `height` from its current value to `0`. Given how CSS handles animations, you cannot use `padding` on a `.collapse` element. Instead, use the class as an independent wrapping element.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+## Example
+
+Click the buttons below to show and hide another element via class changes:
+
+- `.collapse` hides content
+- `.collapsing` is applied during transitions
+- `.collapse.show` shows content
+
+Generally, we recommend using a button with the `data-target` attribute. While not recommended from a semantic point of view, you can also use a link with the `href` attribute (and a `role="button"`). In both cases, the `data-toggle="collapse"` is required.
+
+{{< example >}}
+<p>
+  <a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
+    Link with href
+  </a>
+  <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
+    Button with data-target
+  </button>
+</p>
+<div class="collapse" id="collapseExample">
+  <div class="card card-body">
+    Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.
+  </div>
+</div>
+{{< /example >}}
+
+## Multiple targets
+
+A `<button>` or `<a>` can show and hide multiple elements by referencing them with a JQuery selector in its `href` or `data-target` attribute.
+Multiple `<button>` or `<a>` can show and hide an element if they each reference it with their `href` or `data-target` attribute
+
+{{< example >}}
+<p>
+  <a class="btn btn-primary" data-toggle="collapse" href="#multiCollapseExample1" role="button" aria-expanded="false" aria-controls="multiCollapseExample1">Toggle first element</a>
+  <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#multiCollapseExample2" aria-expanded="false" aria-controls="multiCollapseExample2">Toggle second element</button>
+  <button class="btn btn-primary" type="button" data-toggle="collapse" data-target=".multi-collapse" aria-expanded="false" aria-controls="multiCollapseExample1 multiCollapseExample2">Toggle both elements</button>
+</p>
+<div class="row">
+  <div class="col">
+    <div class="collapse multi-collapse" id="multiCollapseExample1">
+      <div class="card card-body">
+        Some placeholder content for the first collapse component of this multi-collapse example. This panel is hidden by default but revealed when the user activates the relevant trigger.
+      </div>
+    </div>

+  <div class="col">
+    <div class="collapse multi-collapse" id="multiCollapseExample2">
+      <div class="card card-body">
+        Some placeholder content for the second collapse component of this multi-collapse example. This panel is hidden by default but revealed when the user activates the relevant trigger.
+      </div>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+## Accordion example
+
+Using the [card]({{< docsref "/components/card" >}}) component, you can extend the default collapse behavior to create an accordion. To properly achieve the accordion style, be sure to use `.accordion` as a wrapper.
+
+{{< example >}}
+<div class="accordion" id="accordionExample">
+  <div class="card">
+    <div class="card-header" id="headingOne">
+      <h2 class="mb-0">
+        <button class="btn btn-link btn-block text-left" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
+          Collapsible Group Item #1
+        </button>
+      </h2>
+    </div>
+
+    <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">

+
+## Accessibility
+
+Be sure to add `aria-expanded` to the control element. This attribute explicitly conveys the current state of the collapsible element tied to the control to screen readers and similar assistive technologies. If the collapsible element is closed by default, the attribute on the control element should have a value of `aria-expanded="false"`. If you've set the collapsible element to be open by default using the `show` class, set `aria-expanded="true"` on the control instead. The plugin will automatically toggle this attribute on the control based on whether or not the collapsible element has been opened or closed (via JavaScript, or because the user triggered another control element also tied to the same collapsible element). If the control element's HTML element is not a button (e.g., an `<a>` or `<div>`), the attribute `role="button"` should be added to the element.
+
+If your control element is targeting a single collapsible element – i.e. the `data-target` attribute is pointing to an `id` selector – you should add the `aria-controls` attribute to the control element, containing the `id` of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.
+
+Note that Bootstrap's current implementation does not cover the various keyboard interactions described in the [WAI-ARIA Authoring Practices 1.1 accordion pattern](https://www.w3.org/TR/wai-aria-practices-1.1/#accordion) - you will need to include these yourself with custom JavaScript.
+
+## Usage
+
+The collapse plugin utilizes a few classes to handle the heavy lifting:
+
+- `.collapse` hides the content
+- `.collapse.show` shows the content
+- `.collapsing` is added when the transition starts, and removed when it finishes
+
+These classes can be found in `_transitions.scss`.
+
+### Via data attributes
+
+Just add `data-toggle="collapse"` and a `data-target` to the element to automatically assign control of one or more collapsible elements. The `data-target` attribute accepts a CSS selector to apply the collapse to. Be sure to add the class `collapse` to the collapsible element. If you'd like it to default open, add the additional class `show`.
+
+To add accordion-like group management to a collapsible area, add the data attribute `data-parent="#selector"`. Refer to the demo to see this in action.
+
+### Via JavaScript
+
+Enable manually with:
+
+```js
+$('.collapse').collapse()
+```
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-parent=""`.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 50px;">Type</th>
+      <th style="width: 50px;">Default</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>parent</td>
+      <td>selector | jQuery object | DOM element </td>
+      <td>false</td>
+      <td>If parent is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the <code>card</code> class). The attribute has to be set on the target collapsible area.</td>
+    </tr>
+    <tr>
+      <td>toggle</td>
+      <td>boolean</td>
+      <td>true</td>
+      <td>Toggles the collapsible element on invocation</td>
+    </tr>

+
+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### `.collapse(options)`
+
+Activates your content as a collapsible element. Accepts an optional options `object`.
+
+```js
+$('#myCollapsible').collapse({
+  toggle: false
+})
+```
+
+#### `.collapse('toggle')`
+
+Toggles a collapsible element to shown or hidden. **Returns to the caller before the collapsible element has actually been shown or hidden** (i.e. before the `shown.bs.collapse` or `hidden.bs.collapse` event occurs).
+
+#### `.collapse('show')`
+
+Shows a collapsible element. **Returns to the caller before the collapsible element has actually been shown** (i.e. before the `shown.bs.collapse` event occurs).
+
+#### `.collapse('hide')`
+
+Hides a collapsible element. **Returns to the caller before the collapsible element has actually been hidden** (i.e. before the `hidden.bs.collapse` event occurs).
+
+#### `.collapse('dispose')`
+
+Destroys an element's collapse.
+
+### Events
+
+Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 150px;">Event Type</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>show.bs.collapse</td>
+      <td>This event fires immediately when the <code>show</code> instance method is called.</td>
+    </tr>
+    <tr>
+      <td>shown.bs.collapse</td>
+      <td>This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete).</td>
+    </tr>
+    <tr>
+      <td>hide.bs.collapse</td>
+      <td>This event is fired immediately when the <code>hide</code> method has been called.</td>
+    </tr>
+    <tr>
+      <td>hidden.bs.collapse</td>
+      <td>This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete).</td>
+    </tr>
+  </tbody>
+</table>
+
+```js
+$('#myCollapsible').on('hidden.bs.collapse', function () {
+  // do something...
+})
+```

+title: Dropdowns
+description: Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
+group: components
+toc: true
+---
+
+## Overview
+
+Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They're made interactive with the included Bootstrap dropdown JavaScript plugin. They're toggled by clicking, not by hovering; this is [an intentional design decision](https://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/).
+
+Dropdowns are built on a third party library, [Popper](https://popper.js.org/), which provides dynamic positioning and viewport detection. Be sure to include [popper.min.js]({{< param "cdn.popper" >}}) before Bootstrap's JavaScript or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper. Popper isn't used to position dropdowns in navbars though as dynamic positioning isn't required.
+
+If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+
+## Accessibility
+
+The [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr>](https://www.w3.org/TR/wai-aria/) standard defines an actual [`role="menu"` widget](https://www.w3.org/WAI/PF/aria/roles#menu), but this is specific to application-like menus which trigger actions or functions. <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus can only contain menu items, checkbox menu items, radio button menu items, radio button groups, and sub-menus.
+
+Bootstrap's dropdowns, on the other hand, are designed to be generic and applicable to a variety of situations and markup structures. For instance, it is possible to create dropdowns that contain additional inputs and form controls, such as search fields or login forms. For this reason, Bootstrap does not expect (nor automatically add) any of the `role` and `aria-` attributes required for true <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus. Authors will have to include these more specific attributes themselves.
+
+However, Bootstrap does add built-in support for most standard keyboard menu interactions, such as the ability to move through individual `.dropdown-item` elements using the cursor keys and close the menu with the <kbd>ESC</kbd> key.
+
+## Examples
+
+Wrap the dropdown's toggle (your button or link) and the dropdown menu within `.dropdown`, or another element that declares `position: relative;`. Dropdowns can be triggered from `<a>` or `<button>` elements to better fit your potential needs.
+
+### Single button
+
+Any single `.btn` can be turned into a dropdown toggle with some markup changes. Here's how you can put them to work with either `<button>` elements:
+
+{{< example >}}
+<div class="dropdown">
+  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+    Dropdown button
+  </button>
+  <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
+    <a class="dropdown-item" href="#">Action</a>
+    <a class="dropdown-item" href="#">Another action</a>
+    <a class="dropdown-item" href="#">Something else here</a>
+  </div>
+</div>
+{{< /example >}}
+
+And with `<a>` elements:
+
+{{< example >}}
+<div class="dropdown">
+  <a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+    Dropdown link
+  </a>
+
+  <div class="dropdown-menu" aria-labelledby="dropdownMenuLink">
+    <a class="dropdown-item" href="#">Action</a>
+    <a class="dropdown-item" href="#">Another action</a>
+    <a class="dropdown-item" href="#">Something else here</a>
+  </div>
+</div>
+{{< /example >}}
+
+The best part is you can do this with any button variant, too:
+
+<div class="bd-example">
+  <div class="btn-group">
+    <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Primary</button>
+    <div class="dropdown-menu">
+      <a class="dropdown-item" href="#">Action</a>
+      <a class="dropdown-item" href="#">Another action</a>
+      <a class="dropdown-item" href="#">Something else here</a>

+      <div class="dropdown-divider"></div>
+      <a class="dropdown-item" href="#">Separated link</a>
+    </div>
+  </div><!-- /btn-group -->
+  <div class="btn-group">
+    <button type="button" class="btn btn-warning dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Warning</button>
+    <div class="dropdown-menu">
+      <a class="dropdown-item" href="#">Action</a>
+      <a class="dropdown-item" href="#">Another action</a>
+      <a class="dropdown-item" href="#">Something else here</a>
+      <div class="dropdown-divider"></div>
+      <a class="dropdown-item" href="#">Separated link</a>
+    </div>
+  </div><!-- /btn-group -->
+  <div class="btn-group">

+      <div class="dropdown-divider"></div>
+      <a class="dropdown-item" href="#">Separated link</a>
+    </div>
+  </div><!-- /btn-group -->
+</div>
+
+```html
+<!-- Example single danger button -->
+<div class="btn-group">
+  <button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+    Action
+  </button>
+  <div class="dropdown-menu">
+    <a class="dropdown-item" href="#">Action</a>
+    <a class="dropdown-item" href="#">Another action</a>
+    <a class="dropdown-item" href="#">Something else here</a>
+    <div class="dropdown-divider"></div>
+    <a class="dropdown-item" href="#">Separated link</a>
+  </div>
+</div>
+```
+
+### Split button
+
+Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of `.dropdown-toggle-split` for proper spacing around the dropdown caret.
+
+We use this extra class to reduce the horizontal `padding` on either side of the caret by 25% and remove the `margin-left` that's added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.
+
+<div class="bd-example">
+  <div class="btn-group">
+    <button type="button" class="btn btn-primary">Primary</button>
+    <button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

+## Directions
+
+### Dropup
+
+Trigger dropdown menus above elements by adding `.dropup` to the parent element.
+
+<div class="bd-example">
+  <div class="btn-group dropup">
+    <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

+
+## Menu items
+
+Historically dropdown menu contents *had* to be links, but that's no longer the case with v4. Now you can optionally use `<button>` elements in your dropdowns instead of just `<a>`s.
+
+{{< example >}}
+<div class="dropdown">
+  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+    Dropdown
+  </button>
+  <div class="dropdown-menu" aria-labelledby="dropdownMenu2">
+    <button class="dropdown-item" type="button">Action</button>
+    <button class="dropdown-item" type="button">Another action</button>
+    <button class="dropdown-item" type="button">Something else here</button>
+  </div>
+</div>
+{{< /example >}}
+
+You can also create non-interactive dropdown items with `.dropdown-item-text`. Feel free to style further with custom CSS or text utilities.
+
+{{< example >}}
+<div class="dropdown-menu">
+  <span class="dropdown-item-text">Dropdown item text</span>
+  <a class="dropdown-item" href="#">Action</a>
+  <a class="dropdown-item" href="#">Another action</a>
+  <a class="dropdown-item" href="#">Something else here</a>
+</div>
+{{< /example >}}
+
+### Active
+
+Add `.active` to items in the dropdown to **style them as active**.
+
+{{< example >}}
+<div class="dropdown-menu">
+  <a class="dropdown-item" href="#">Regular link</a>
+  <a class="dropdown-item active" href="#">Active link</a>
+  <a class="dropdown-item" href="#">Another link</a>
+</div>
+{{< /example >}}
+
+### Disabled
+
+Add `.disabled` to items in the dropdown to **style them as disabled**.
+
+{{< example >}}
+<div class="dropdown-menu">
+  <a class="dropdown-item" href="#">Regular link</a>
+  <a class="dropdown-item disabled" href="#" tabindex="-1" aria-disabled="true">Disabled link</a>
+  <a class="dropdown-item" href="#">Another link</a>
+</div>
+{{< /example >}}
+
+## Menu alignment
+
+By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add `.dropdown-menu-right` to a `.dropdown-menu` to right align the dropdown menu.
+
+{{< callout info >}}
+**Heads up!** Dropdowns are positioned thanks to Popper (except when they are contained in a navbar).
+{{< /callout >}}
+
+{{< example >}}
+<div class="btn-group">
+  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+    Right-aligned menu
+  </button>
+  <div class="dropdown-menu dropdown-menu-right">
+    <button class="dropdown-item" type="button">Action</button>
+    <button class="dropdown-item" type="button">Another action</button>
+    <button class="dropdown-item" type="button">Something else here</button>
+  </div>
+</div>
+{{< /example >}}
+
+### Responsive alignment
+
+If you want to use responsive alignment, disable dynamic positioning by adding the `data-display="static"` attribute and use the responsive variation classes.
+
+To align **right** the dropdown menu with the given breakpoint or larger, add `.dropdown-menu{-sm|-md|-lg|-xl}-right`.
+
+{{< example >}}
+<div class="btn-group">
+  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" data-display="static" aria-haspopup="true" aria-expanded="false">
+    Left-aligned but right aligned when large screen
+  </button>
+  <div class="dropdown-menu dropdown-menu-lg-right">
+    <button class="dropdown-item" type="button">Action</button>
+    <button class="dropdown-item" type="button">Another action</button>
+    <button class="dropdown-item" type="button">Something else here</button>
+  </div>
+</div>
+{{< /example >}}
+
+To align **left** the dropdown menu with the given breakpoint or larger, add `.dropdown-menu-right` and `.dropdown-menu{-sm|-md|-lg|-xl}-left`.
+
+{{< example >}}
+<div class="btn-group">
+  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" data-display="static" aria-haspopup="true" aria-expanded="false">
+    Right-aligned but left aligned when large screen
+  </button>
+  <div class="dropdown-menu dropdown-menu-right dropdown-menu-lg-left">
+    <button class="dropdown-item" type="button">Action</button>
+    <button class="dropdown-item" type="button">Another action</button>
+    <button class="dropdown-item" type="button">Something else here</button>
+  </div>
+</div>
+{{< /example >}}
+
+Note that you don't need to add a `data-display="static"` attribute to dropdown buttons in navbars, since Popper isn't used in navbars.
+
+## Menu content
+
+### Headers
+
+Add a header to label sections of actions in any dropdown menu.
+
+{{< example >}}
+<div class="dropdown-menu">
+  <h6 class="dropdown-header">Dropdown header</h6>
+  <a class="dropdown-item" href="#">Action</a>
+  <a class="dropdown-item" href="#">Another action</a>
+</div>
+{{< /example >}}
+
+### Dividers
+
+Separate groups of related menu items with a divider.
+
+{{< example >}}
+<div class="dropdown-menu">
+  <a class="dropdown-item" href="#">Action</a>
+  <a class="dropdown-item" href="#">Another action</a>
+  <a class="dropdown-item" href="#">Something else here</a>
+  <div class="dropdown-divider"></div>
+  <a class="dropdown-item" href="#">Separated link</a>
+</div>
+{{< /example >}}
+
+### Text
+
+Place any freeform text within a dropdown menu with text and use [spacing utilities]({{< docsref "/utilities/spacing" >}}). Note that you'll likely need additional sizing styles to constrain the menu width.
+
+{{< example >}}
+<div class="dropdown-menu p-4 text-muted" style="max-width: 200px;">
+  <p>
+    Some example text that's free-flowing within the dropdown menu.
+  </p>
+  <p class="mb-0">
+    And this is more example text.
+  </p>
+</div>
+{{< /example >}}
+
+### Forms
+
+Put a form within a dropdown menu, or make it into a dropdown menu, and use [margin or padding utilities]({{< docsref "/utilities/spacing" >}}) to give it the negative space you require.
+
+{{< example >}}
+<div class="dropdown-menu">
+  <form class="px-4 py-3">
+    <div class="form-group">
+      <label for="exampleDropdownFormEmail1">Email address</label>
+      <input type="email" class="form-control" id="exampleDropdownFormEmail1" placeholder="email@example.com">
+    </div>
+    <div class="form-group">
+      <label for="exampleDropdownFormPassword1">Password</label>
+      <input type="password" class="form-control" id="exampleDropdownFormPassword1" placeholder="Password">
+    </div>
+    <div class="form-group">
+      <div class="form-check">
+        <input type="checkbox" class="form-check-input" id="dropdownCheck">
+        <label class="form-check-label" for="dropdownCheck">
+          Remember me
+        </label>
+      </div>
+    </div>
+    <button type="submit" class="btn btn-primary">Sign in</button>
+  </form>
+  <div class="dropdown-divider"></div>
+  <a class="dropdown-item" href="#">New around here? Sign up</a>
+  <a class="dropdown-item" href="#">Forgot password?</a>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<form class="dropdown-menu p-4">
+  <div class="form-group">
+    <label for="exampleDropdownFormEmail2">Email address</label>
+    <input type="email" class="form-control" id="exampleDropdownFormEmail2" placeholder="email@example.com">
+  </div>
+  <div class="form-group">
+    <label for="exampleDropdownFormPassword2">Password</label>
+    <input type="password" class="form-control" id="exampleDropdownFormPassword2" placeholder="Password">
+  </div>
+  <div class="form-group">
+    <div class="form-check">
+      <input type="checkbox" class="form-check-input" id="dropdownCheck2">
+      <label class="form-check-label" for="dropdownCheck2">
+        Remember me
+      </label>
+    </div>
+  </div>
+  <button type="submit" class="btn btn-primary">Sign in</button>
+</form>
+{{< /example >}}
+
+## Dropdown options
+
+Use `data-offset` or `data-reference` to change the location of the dropdown.
+
+{{< example >}}
+<div class="d-flex">
+  <div class="dropdown mr-1">
+    <button type="button" class="btn btn-secondary dropdown-toggle" id="dropdownMenuOffset" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" data-offset="10,20">
+      Offset
+    </button>
+    <div class="dropdown-menu" aria-labelledby="dropdownMenuOffset">
+      <a class="dropdown-item" href="#">Action</a>
+      <a class="dropdown-item" href="#">Another action</a>
+      <a class="dropdown-item" href="#">Something else here</a>
+    </div>
+  </div>
+  <div class="btn-group">
+    <button type="button" class="btn btn-secondary">Reference</button>
+    <button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" id="dropdownMenuReference" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" data-reference="parent">
+      <span class="sr-only">Toggle Dropdown</span>
+    </button>
+    <div class="dropdown-menu" aria-labelledby="dropdownMenuReference">
+      <a class="dropdown-item" href="#">Action</a>
+      <a class="dropdown-item" href="#">Another action</a>
+      <a class="dropdown-item" href="#">Something else here</a>
+      <div class="dropdown-divider"></div>
+      <a class="dropdown-item" href="#">Separated link</a>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+## Usage
+
+Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the `.show` class on the parent `.dropdown-menu`. The `data-toggle="dropdown"` attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.
+
+{{< callout info >}}
+On touch-enabled devices, opening a dropdown adds empty (`$.noop`) `mouseover` handlers to the immediate children of the `<body>` element. This admittedly ugly hack is necessary to work around a [quirk in iOS' event delegation](https://www.quirksmode.org/blog/archives/2014/02/mouse_event_bub.html), which would otherwise prevent a tap anywhere outside of the dropdown from triggering the code that closes the dropdown. Once the dropdown is closed, these additional empty `mouseover` handlers are removed.
+{{< /callout >}}
+
+### Via data attributes
+
+Add `data-toggle="dropdown"` to a link or button to toggle a dropdown.
+
+```html
+<div class="dropdown">
+  <button id="dLabel" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+    Dropdown trigger
+  </button>
+  <div class="dropdown-menu" aria-labelledby="dLabel">
+    ...
+  </div>
+</div>
+```
+
+### Via JavaScript
+
+Call the dropdowns via JavaScript:
+
+```js
+$('.dropdown-toggle').dropdown()
+```
+
+{{< callout info >}}
+##### `data-toggle="dropdown"` still required
+
+Regardless of whether you call your dropdown via JavaScript or instead use the data-api, `data-toggle="dropdown"` is always required to be present on the dropdown's trigger element.
+{{< /callout >}}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-offset=""`.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 100px;">Type</th>

+        <p>When a function is used to determine the offset, it is called with an object containing the offset data as its first argument. The function must return an object with the same structure. The triggering element DOM node is passed as the second argument.</p>

+
+Note when `boundary` is set to any value other than `'scrollParent'`, the style `position: static` is applied to the `.dropdown` container.
+
+### Methods
+
+| Method | Description |
+| --- | --- |
+| `$().dropdown('toggle')` | Toggles the dropdown menu of a given navbar or tabbed navigation. |
+| `$().dropdown('show')` | Shows the dropdown menu of a given navbar or tabbed navigation. |
+| `$().dropdown('hide')` | Hides the dropdown menu of a given navbar or tabbed navigation. |
+| `$().dropdown('update')` | Updates the position of an element's dropdown. |
+| `$().dropdown('dispose')` | Destroys an element's dropdown. |
+
+### Events
+
+All dropdown events are fired at the `.dropdown-menu`'s parent element and have a `relatedTarget` property, whose value is the toggling anchor element.
+`hide.bs.dropdown` and `hidden.bs.dropdown` events have a `clickEvent` property (only when the original event type is `click`) that contains an Event Object for the click event.
+
+| Event | Description |
+| --- | --- |

+
+## Overview
+
+Bootstrap's form controls expand on [our Rebooted form styles]({{< docsref "/content/reboot#forms" >}}) with classes. Use these classes to opt into their customized displays for a more consistent rendering across browsers and devices.
+
+Be sure to use an appropriate `type` attribute on all inputs (e.g., `email` for email address or `number` for numerical information) to take advantage of newer input controls like email verification, number selection, and more.
+
+Here's a quick example to demonstrate Bootstrap's form styles. Keep reading for documentation on required classes, form layout, and more.
+
+{{< example >}}
+<form>
+  <div class="form-group">
+    <label for="exampleInputEmail1">Email address</label>
+    <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp">
+    <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
+  </div>
+  <div class="form-group">
+    <label for="exampleInputPassword1">Password</label>
+    <input type="password" class="form-control" id="exampleInputPassword1">
+  </div>
+  <div class="form-group form-check">
+    <input type="checkbox" class="form-check-input" id="exampleCheck1">
+    <label class="form-check-label" for="exampleCheck1">Check me out</label>
+  </div>
+  <button type="submit" class="btn btn-primary">Submit</button>
+</form>
+{{< /example >}}
+
+## Form controls
+
+Textual form controls—like `<input>`s, `<select>`s, and `<textarea>`s—are styled with the `.form-control` class. Included are styles for general appearance, focus state, sizing, and more.
+
+Be sure to explore our [custom forms](#custom-forms) to further style `<select>`s.
+
+{{< example >}}
+<form>
+  <div class="form-group">
+    <label for="exampleFormControlInput1">Email address</label>
+    <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
+  </div>
+  <div class="form-group">
+    <label for="exampleFormControlSelect1">Example select</label>
+    <select class="form-control" id="exampleFormControlSelect1">
+      <option>1</option>
+      <option>2</option>
+      <option>3</option>
+      <option>4</option>
+      <option>5</option>
+    </select>
+  </div>
+  <div class="form-group">
+    <label for="exampleFormControlSelect2">Example multiple select</label>
+    <select multiple class="form-control" id="exampleFormControlSelect2">
+      <option>1</option>
+      <option>2</option>
+      <option>3</option>
+      <option>4</option>
+      <option>5</option>
+    </select>
+  </div>
+  <div class="form-group">
+    <label for="exampleFormControlTextarea1">Example textarea</label>
+    <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
+  </div>
+</form>
+{{< /example >}}
+
+For file inputs, swap the `.form-control` for `.form-control-file`.
+
+{{< example >}}
+<form>
+  <div class="form-group">
+    <label for="exampleFormControlFile1">Example file input</label>
+    <input type="file" class="form-control-file" id="exampleFormControlFile1">
+  </div>
+</form>
+{{< /example >}}
+
+### Sizing
+
+Set heights using classes like `.form-control-lg` and `.form-control-sm`.
+
+{{< example >}}
+<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg">
+<input class="form-control" type="text" placeholder="Default input">
+<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm">
+{{< /example >}}
+
+{{< example >}}
+<select class="form-control form-control-lg">
+  <option>Large select</option>
+</select>
+<select class="form-control">
+  <option>Default select</option>
+</select>
+<select class="form-control form-control-sm">
+  <option>Small select</option>
+</select>
+{{< /example >}}
+
+### Readonly
+
+Add the `readonly` boolean attribute on an input to prevent modification of the input's value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.
+
+{{< example >}}
+<input class="form-control" type="text" placeholder="Readonly input here..." readonly>
+{{< /example >}}
+
+### Readonly plain text
+
+If you want to have `<input readonly>` elements in your form styled as plain text, use the `.form-control-plaintext` class to remove the default form field styling and preserve the correct margin and padding.
+
+{{< example >}}
+<form>
+  <div class="form-group row">
+    <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
+    <div class="col-sm-10">
+      <input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">
+    </div>
+  </div>
+  <div class="form-group row">
+    <label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
+    <div class="col-sm-10">
+      <input type="password" class="form-control" id="inputPassword">
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+{{< example >}}
+<form class="form-inline">
+  <div class="form-group mb-2">
+    <label for="staticEmail2" class="sr-only">Email</label>
+    <input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="email@example.com">
+  </div>
+  <div class="form-group mx-sm-3 mb-2">
+    <label for="inputPassword2" class="sr-only">Password</label>
+    <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
+  </div>
+  <button type="submit" class="btn btn-primary mb-2">Confirm identity</button>
+</form>
+{{< /example >}}
+
+## Range Inputs
+
+Set horizontally scrollable range inputs using `.form-control-range`.
+
+{{< example >}}
+<form>
+  <div class="form-group">
+    <label for="formControlRange">Example Range input</label>
+    <input type="range" class="form-control-range" id="formControlRange">
+  </div>
+</form>
+{{< /example >}}
+
+## Checkboxes and radios
+
+Default checkboxes and radios are improved upon with the help of `.form-check`, **a single class for both input types that improves the layout and behavior of their HTML elements**. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
+
+Disabled checkboxes and radios are supported. The `disabled` attribute will apply a lighter color to help indicate the input's state.
+
+Checkboxes and radio buttons support HTML-based form validation and provide concise, accessible labels. As such, our `<input>`s and `<label>`s are sibling elements as opposed to an `<input>` within a `<label>`. This is slightly more verbose as you must specify `id` and `for` attributes to relate the `<input>` and `<label>`.
+
+### Default (stacked)
+
+By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with `.form-check`.
+
+{{< example >}}
+<div class="form-check">
+  <input class="form-check-input" type="checkbox" value="" id="defaultCheck1">
+  <label class="form-check-label" for="defaultCheck1">
+    Default checkbox
+  </label>
+</div>
+<div class="form-check">
+  <input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled>
+  <label class="form-check-label" for="defaultCheck2">
+    Disabled checkbox
+  </label>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="form-check">
+  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked>
+  <label class="form-check-label" for="exampleRadios1">
+    Default radio
+  </label>
+</div>
+<div class="form-check">
+  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2">
+  <label class="form-check-label" for="exampleRadios2">
+    Second default radio
+  </label>
+</div>
+<div class="form-check">
+  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled>
+  <label class="form-check-label" for="exampleRadios3">
+    Disabled radio
+  </label>
+</div>
+{{< /example >}}
+
+### Inline
+
+Group checkboxes or radios on the same horizontal row by adding `.form-check-inline` to any `.form-check`.
+
+{{< example >}}
+<div class="form-check form-check-inline">
+  <input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1">
+  <label class="form-check-label" for="inlineCheckbox1">1</label>
+</div>
+<div class="form-check form-check-inline">
+  <input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2">
+  <label class="form-check-label" for="inlineCheckbox2">2</label>
+</div>
+<div class="form-check form-check-inline">
+  <input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled>
+  <label class="form-check-label" for="inlineCheckbox3">3 (disabled)</label>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="form-check form-check-inline">
+  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
+  <label class="form-check-label" for="inlineRadio1">1</label>
+</div>
+<div class="form-check form-check-inline">
+  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
+  <label class="form-check-label" for="inlineRadio2">2</label>
+</div>
+<div class="form-check form-check-inline">
+  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3" disabled>
+  <label class="form-check-label" for="inlineRadio3">3 (disabled)</label>
+</div>
+{{< /example >}}
+
+### Without labels
+
+Add `.position-static` to inputs within `.form-check` that don't have any label text. Remember to still provide some form of accessible name for assistive technologies (for instance, using `aria-label`).
+
+{{< example >}}
+<div class="form-check">
+  <input class="form-check-input position-static" type="checkbox" id="blankCheckbox" value="option1" aria-label="...">
+</div>
+<div class="form-check">
+  <input class="form-check-input position-static" type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="...">
+</div>
+{{< /example >}}
+
+## Layout
+
+Since Bootstrap applies `display: block` and `width: 100%` to almost all our form controls, forms will by default stack vertically. Additional classes can be used to vary this layout on a per-form basis.
+
+### Form groups
+
+The `.form-group` class is the easiest way to add some structure to forms. It provides a flexible class that encourages proper grouping of labels, controls, optional help text, and form validation messaging. By default it only applies `margin-bottom`, but it picks up additional styles in `.form-inline` as needed. Use it with `<fieldset>`s, `<div>`s, or nearly any other element.
+
+{{< example >}}
+<form>
+  <div class="form-group">
+    <label for="formGroupExampleInput">Example label</label>
+    <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input placeholder">
+  </div>
+  <div class="form-group">
+    <label for="formGroupExampleInput2">Another label</label>
+    <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input placeholder">
+  </div>
+</form>
+{{< /example >}}
+
+### Form grid
+
+More complex forms can be built using our grid classes. Use these for form layouts that require multiple columns, varied widths, and additional alignment options.
+
+{{< example >}}
+<form>
+  <div class="row">
+    <div class="col">
+      <input type="text" class="form-control" placeholder="First name">
+    </div>
+    <div class="col">
+      <input type="text" class="form-control" placeholder="Last name">
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+#### Form row
+
+You may also swap `.row` for `.form-row`, a variation of our standard grid row that overrides the default column gutters for tighter and more compact layouts.
+
+{{< example >}}
+<form>
+  <div class="form-row">
+    <div class="col">
+      <input type="text" class="form-control" placeholder="First name">
+    </div>
+    <div class="col">
+      <input type="text" class="form-control" placeholder="Last name">
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+More complex layouts can also be created with the grid system.
+
+{{< example >}}
+<form>
+  <div class="form-row">
+    <div class="form-group col-md-6">
+      <label for="inputEmail4">Email</label>
+      <input type="email" class="form-control" id="inputEmail4">
+    </div>
+    <div class="form-group col-md-6">
+      <label for="inputPassword4">Password</label>
+      <input type="password" class="form-control" id="inputPassword4">
+    </div>
+  </div>
+  <div class="form-group">
+    <label for="inputAddress">Address</label>
+    <input type="text" class="form-control" id="inputAddress" placeholder="1234 Main St">
+  </div>
+  <div class="form-group">
+    <label for="inputAddress2">Address 2</label>
+    <input type="text" class="form-control" id="inputAddress2" placeholder="Apartment, studio, or floor">
+  </div>
+  <div class="form-row">
+    <div class="form-group col-md-6">
+      <label for="inputCity">City</label>
+      <input type="text" class="form-control" id="inputCity">
+    </div>
+    <div class="form-group col-md-4">
+      <label for="inputState">State</label>
+      <select id="inputState" class="form-control">
+        <option selected>Choose...</option>
+        <option>...</option>
+      </select>
+    </div>
+    <div class="form-group col-md-2">
+      <label for="inputZip">Zip</label>
+      <input type="text" class="form-control" id="inputZip">
+    </div>
+  </div>
+  <div class="form-group">
+    <div class="form-check">
+      <input class="form-check-input" type="checkbox" id="gridCheck">
+      <label class="form-check-label" for="gridCheck">
+        Check me out
+      </label>
+    </div>
+  </div>
+  <button type="submit" class="btn btn-primary">Sign in</button>
+</form>
+{{< /example >}}
+
+#### Horizontal form
+
+Create horizontal forms with the grid by adding the `.row` class to form groups and using the `.col-*-*` classes to specify the width of your labels and controls. Be sure to add `.col-form-label` to your `<label>`s as well so they're vertically centered with their associated form controls.
+
+At times, you maybe need to use margin or padding utilities to create that perfect alignment you need. For example, we've removed the `padding-top` on our stacked radio inputs label to better align the text baseline.
+
+{{< example >}}
+<form>
+  <div class="form-group row">
+    <label for="inputEmail3" class="col-sm-2 col-form-label">Email</label>
+    <div class="col-sm-10">
+      <input type="email" class="form-control" id="inputEmail3">
+    </div>
+  </div>
+  <div class="form-group row">
+    <label for="inputPassword3" class="col-sm-2 col-form-label">Password</label>
+    <div class="col-sm-10">
+      <input type="password" class="form-control" id="inputPassword3">
+    </div>
+  </div>
+  <fieldset class="form-group row">
+    <legend class="col-form-label col-sm-2 float-sm-left pt-0">Radios</legend>
+    <div class="col-sm-10">
+      <div class="form-check">
+        <input class="form-check-input" type="radio" name="gridRadios" id="gridRadios1" value="option1" checked>
+        <label class="form-check-label" for="gridRadios1">
+          First radio
+        </label>
+      </div>
+      <div class="form-check">
+        <input class="form-check-input" type="radio" name="gridRadios" id="gridRadios2" value="option2">
+        <label class="form-check-label" for="gridRadios2">
+          Second radio
+        </label>
+      </div>
+      <div class="form-check disabled">
+        <input class="form-check-input" type="radio" name="gridRadios" id="gridRadios3" value="option3" disabled>
+        <label class="form-check-label" for="gridRadios3">
+          Third disabled radio
+        </label>
+      </div>
+    </div>
+  </fieldset>
+  <div class="form-group row">
+    <div class="col-sm-10 offset-sm-2">
+      <div class="form-check">
+        <input class="form-check-input" type="checkbox" id="gridCheck1">
+        <label class="form-check-label" for="gridCheck1">
+          Example checkbox
+        </label>
+      </div>
+    </div>
+  </div>
+  <div class="form-group row">
+    <div class="col-sm-10">
+      <button type="submit" class="btn btn-primary">Sign in</button>
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+##### Horizontal form label sizing
+
+Be sure to use `.col-form-label-sm` or `.col-form-label-lg` to your `<label>`s or `<legend>`s to correctly follow the size of `.form-control-lg` and `.form-control-sm`.
+
+{{< example >}}
+<form>
+  <div class="form-group row">
+    <label for="colFormLabelSm" class="col-sm-2 col-form-label col-form-label-sm">Email</label>
+    <div class="col-sm-10">
+      <input type="email" class="form-control form-control-sm" id="colFormLabelSm" placeholder="col-form-label-sm">
+    </div>
+  </div>
+  <div class="form-group row">
+    <label for="colFormLabel" class="col-sm-2 col-form-label">Email</label>
+    <div class="col-sm-10">
+      <input type="email" class="form-control" id="colFormLabel" placeholder="col-form-label">
+    </div>
+  </div>
+  <div class="form-group row">
+    <label for="colFormLabelLg" class="col-sm-2 col-form-label col-form-label-lg">Email</label>
+    <div class="col-sm-10">
+      <input type="email" class="form-control form-control-lg" id="colFormLabelLg" placeholder="col-form-label-lg">
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+#### Column sizing
+
+As shown in the previous examples, our grid system allows you to place any number of `.col`s within a `.row` or `.form-row`. They'll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining `.col`s equally split the rest, with specific column classes like `.col-7`.
+
+{{< example >}}
+<form>
+  <div class="form-row">
+    <div class="col-7">
+      <input type="text" class="form-control" placeholder="City">
+    </div>
+    <div class="col">
+      <input type="text" class="form-control" placeholder="State">
+    </div>
+    <div class="col">
+      <input type="text" class="form-control" placeholder="Zip">
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+#### Auto-sizing
+
+The example below uses a flexbox utility to vertically center the contents and changes `.col` to `.col-auto` so that your columns only take up as much space as needed. Put another way, the column sizes itself based on the contents.
+
+{{< example >}}
+<form>
+  <div class="form-row align-items-center">
+    <div class="col-auto">
+      <label class="sr-only" for="inlineFormInput">Name</label>
+      <input type="text" class="form-control mb-2" id="inlineFormInput" placeholder="Jane Doe">
+    </div>
+    <div class="col-auto">
+      <label class="sr-only" for="inlineFormInputGroup">Username</label>
+      <div class="input-group mb-2">
+        <div class="input-group-prepend">
+          <div class="input-group-text">@</div>
+        </div>
+        <input type="text" class="form-control" id="inlineFormInputGroup" placeholder="Username">
+      </div>
+    </div>
+    <div class="col-auto">
+      <div class="form-check mb-2">
+        <input class="form-check-input" type="checkbox" id="autoSizingCheck">
+        <label class="form-check-label" for="autoSizingCheck">
+          Remember me
+        </label>
+      </div>
+    </div>
+    <div class="col-auto">
+      <button type="submit" class="btn btn-primary mb-2">Submit</button>
+    </div>
+  </div>
+</form>
+{{< /example >}}
+
+You can then remix that once again with size-specific column classes.
+
+{{< example >}}
+<form>
+  <div class="form-row align-items-center">
+    <div class="col-sm-3 my-1">
+      <label class="sr-only" for="inlineFormInputName">Name</label>
+      <input type="text" class="form-control" id="inlineFormInputName" placeholder="Jane Doe">
+    </div>
+    <div class="col-sm-3 my-1">
+      <label class="sr-only" for="inlineFormInputGroupUsername">Username</label>
+      <div class="input-group">
+        <div class="input-group-prepend">
+          <div class="input-group-text">@</div>
+        </div>
+        <input type="text" class="form-control" id="inlineFormInputGroupUsername" placeholder="Username">
+      </div>
+    </div>
+    <div class="col-auto my-1">

+
+### Inline forms
+
+Use the `.form-inline` class to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms vary slightly from their default states.
+
+- Controls are `display: flex`, collapsing any HTML white space and allowing you to provide alignment control with [spacing]({{< docsref "/utilities/spacing" >}}) and [flexbox]({{< docsref "/utilities/flex" >}}) utilities.
+- Controls and input groups receive `width: auto` to override the Bootstrap default `width: 100%`.
+- Controls **only appear inline in viewports that are at least 576px wide** to account for narrow viewports on mobile devices.
+
+You may need to manually address the width and alignment of individual form controls with [spacing utilities]({{< docsref "/utilities/spacing" >}}) (as shown below). Lastly, be sure to always include a `<label>` with each form control, even if you need to hide it from non-screenreader visitors with `.sr-only`.
+
+{{< example >}}
+<form class="form-inline">
+  <label class="sr-only" for="inlineFormInputName2">Name</label>
+  <input type="text" class="form-control mb-2 mr-sm-2" id="inlineFormInputName2" placeholder="Jane Doe">
+
+  <label class="sr-only" for="inlineFormInputGroupUsername2">Username</label>
+  <div class="input-group mb-2 mr-sm-2">
+    <div class="input-group-prepend">
+      <div class="input-group-text">@</div>
+    </div>
+    <input type="text" class="form-control" id="inlineFormInputGroupUsername2" placeholder="Username">
+  </div>
+
+  <div class="form-check mb-2 mr-sm-2">
+    <input class="form-check-input" type="checkbox" id="inlineFormCheck">
+    <label class="form-check-label" for="inlineFormCheck">
+      Remember me
+    </label>
+  </div>
+
+  <button type="submit" class="btn btn-primary mb-2">Submit</button>
+</form>
+{{< /example >}}
+
+Custom form controls and selects are also supported.
+
+{{< example >}}
+<form class="form-inline">
+  <label class="my-1 mr-2" for="inlineFormCustomSelectPref">Preference</label>
+  <select class="custom-select my-1 mr-sm-2" id="inlineFormCustomSelectPref">
+    <option selected>Choose...</option>
+    <option value="1">One</option>
+    <option value="2">Two</option>
+    <option value="3">Three</option>
+  </select>
+
+  <div class="custom-control custom-checkbox my-1 mr-sm-2">
+    <input type="checkbox" class="custom-control-input" id="customControlInline">
+    <label class="custom-control-label" for="customControlInline">Remember my preference</label>
+  </div>
+
+  <button type="submit" class="btn btn-primary my-1">Submit</button>
+</form>
+{{< /example >}}
+
+{{< callout warning >}}
+##### Alternatives to hidden labels
+Assistive technologies such as screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the `.sr-only` class. There are further alternative methods of providing a label for assistive technologies, such as the `aria-label`, `aria-labelledby` or `title` attribute. If none of these are present, assistive technologies may resort to using the `placeholder` attribute, if present, but note that use of `placeholder` as a replacement for other labelling methods is not advised.
+{{< /callout >}}
+
+## Help text
+
+Block-level help text in forms can be created using `.form-text` (previously known as `.help-block` in v3). Inline help text can be flexibly implemented using any inline HTML element and utility classes like `.text-muted`.
+
+{{< callout warning >}}
+##### Associating help text with form controls
+
+Help text should be explicitly associated with the form control it relates to using the `aria-describedby` attribute. This will ensure that assistive technologies—such as screen readers—will announce this help text when the user focuses or enters the control.
+{{< /callout >}}
+
+Help text below inputs can be styled with `.form-text`. This class includes `display: block` and adds some top margin for easy spacing from the inputs above.
+
+{{< example >}}
+<label for="inputPassword5">Password</label>
+<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
+<small id="passwordHelpBlock" class="form-text text-muted">
+  Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
+</small>
+{{< /example >}}
+
+Inline text can use any typical inline HTML element (be it a `<small>`, `<span>`, or something else) with nothing more than a utility class.
+
+{{< example >}}
+<form class="form-inline">
+  <div class="form-group">
+    <label for="inputPassword6">Password</label>
+    <input type="password" id="inputPassword6" class="form-control mx-sm-3" aria-describedby="passwordHelpInline">
+    <small id="passwordHelpInline" class="text-muted">
+      Must be 8-20 characters long.
+    </small>
+  </div>
+</form>
+{{< /example >}}
+
+## Disabled forms
+
+Add the `disabled` boolean attribute on an input to prevent user interactions and make it appear lighter.
+
+```html
+<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
+```
+
+Add the `disabled` attribute to a `<fieldset>` to disable all the controls within.
+
+{{< example >}}
+<form>
+  <fieldset disabled>
+    <legend>Disabled fieldset example</legend>
+    <div class="form-group">
+      <label for="disabledTextInput">Disabled input</label>
+      <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
+    </div>
+    <div class="form-group">
+      <label for="disabledSelect">Disabled select menu</label>
+      <select id="disabledSelect" class="form-control">
+        <option>Disabled select</option>
+      </select>
+    </div>
+    <div class="form-group">
+      <div class="form-check">
+        <input class="form-check-input" type="checkbox" id="disabledFieldsetCheck" disabled>
+        <label class="form-check-label" for="disabledFieldsetCheck">
+          Can't check this
+        </label>
+      </div>
+    </div>
+    <button type="submit" class="btn btn-primary">Submit</button>
+  </fieldset>
+</form>
+{{< /example >}}
+
+{{< callout warning >}}
+##### Caveat with anchors
+
+Browsers treat all native form controls (`<input>`, `<select>`, and `<button>` elements) inside a `<fieldset disabled>` as disabled, preventing both keyboard and mouse interactions on them.
+
+However, if your form also includes custom button-like elements such as `<a ... class="btn btn-*">`, these will only be given a style of `pointer-events: none`. As noted in the section about [disabled state for buttons]({{< docsref "/components/buttons#disabled-state" >}}) (and specifically in the sub-section for anchor elements), this CSS property is not yet standardized and isn't fully supported in Internet Explorer 10. The anchor-based controls will also still be focusable and operable using the keyboard. You must manually modify these controls by adding `tabindex="-1"` to prevent them from receiving focus and `aria-disabled="disabled"` to signal their state to assistive technologies.
+{{< /callout >}}
+
+{{< callout danger >}}
+#### Cross-browser compatibility
+
+While Bootstrap will apply these styles in all browsers, Internet Explorer 11 and below don't fully support the `disabled` attribute on a `<fieldset>`. Use custom JavaScript to disable the fieldset in these browsers.

+
+## Validation
+
+Provide valuable, actionable feedback to your users with HTML5 form validation–[available in all our supported browsers](https://caniuse.com/form-validation). Choose from the browser default validation feedback, or implement custom messages with our built-in classes and starter JavaScript.
+
+{{< callout warning >}}
+We are aware that currently the client-side custom validation styles and tooltips are not accessible, since they are not exposed to assistive technologies. While we work on a solution, we'd recommend either using the server-side option or the default browser validation method.
+{{< /callout >}}
+
+### How it works
+
+Here's how form validation works with Bootstrap:
+
+- HTML form validation is applied via CSS's two pseudo-classes, `:invalid` and `:valid`. It applies to `<input>`, `<select>`, and `<textarea>` elements.
+- Bootstrap scopes the `:invalid` and `:valid` styles to parent `.was-validated` class, usually applied to the `<form>`. Otherwise, any required field without a value shows up as invalid on page load. This way, you may choose when to activate them (typically after form submission is attempted).
+- To reset the appearance of the form (for instance, in the case of dynamic form submissions using AJAX), remove the `.was-validated` class from the `<form>` again after submission.
+- As a fallback, `.is-invalid` and `.is-valid` classes may be used instead of the pseudo-classes for [server side validation](#server-side). They do not require a `.was-validated` parent class.
+- Due to constraints in how CSS works, we cannot (at present) apply styles to a `<label>` that comes before a form control in the DOM without the help of custom JavaScript.
+- All modern browsers support the [constraint validation API](https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#the-constraint-validation-api), a series of JavaScript methods for validating form controls.
+- Feedback messages may utilize the [browser defaults](#browser-defaults) (different for each browser, and unstylable via CSS) or our custom feedback styles with additional HTML and CSS.
+- You may provide custom validity messages with `setCustomValidity` in JavaScript.
+
+With that in mind, consider the following demos for our custom form validation styles, optional server side classes, and browser defaults.
+
+### Custom styles
+
+For custom Bootstrap form validation messages, you'll need to add the `novalidate` boolean attribute to your `<form>`. This disables the browser default feedback tooltips, but still provides access to the form validation APIs in JavaScript. Try to submit the form below; our JavaScript will intercept the submit button and relay feedback to you. When attempting to submit, you'll see the `:invalid` and `:valid` styles applied to your form controls.
+
+Custom feedback styles apply custom colors, borders, focus styles, and background icons to better communicate feedback. Background icons for `<select>`s are only available with `.custom-select`, and not `.form-control`.
+
+{{< example >}}
+<form class="needs-validation" novalidate>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationCustom01">First name</label>
+      <input type="text" class="form-control" id="validationCustom01" value="Mark" required>
+      <div class="valid-feedback">
+        Looks good!
+      </div>
+    </div>
+    <div class="col-md-6 mb-3">
+      <label for="validationCustom02">Last name</label>
+      <input type="text" class="form-control" id="validationCustom02" value="Otto" required>
+      <div class="valid-feedback">
+        Looks good!
+      </div>
+    </div>
+  </div>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationCustom03">City</label>
+      <input type="text" class="form-control" id="validationCustom03" required>
+      <div class="invalid-feedback">
+        Please provide a valid city.
+      </div>
+    </div>
+    <div class="col-md-3 mb-3">
+      <label for="validationCustom04">State</label>
+      <select class="custom-select" id="validationCustom04" required>
+        <option selected disabled value="">Choose...</option>
+        <option>...</option>
+      </select>
+      <div class="invalid-feedback">
+        Please select a valid state.
+      </div>
+    </div>
+    <div class="col-md-3 mb-3">
+      <label for="validationCustom05">Zip</label>
+      <input type="text" class="form-control" id="validationCustom05" required>

+      </label>
+      <div class="invalid-feedback">

+  <button class="btn btn-primary" type="submit">Submit form</button>
+</form>
+
+<script>
+// Example starter JavaScript for disabling form submissions if there are invalid fields
+(function() {
+  'use strict';
+  window.addEventListener('load', function() {
+    // Fetch all the forms we want to apply custom Bootstrap validation styles to
+    var forms = document.getElementsByClassName('needs-validation');
+    // Loop over them and prevent submission
+    var validation = Array.prototype.filter.call(forms, function(form) {
+      form.addEventListener('submit', function(event) {
+        if (form.checkValidity() === false) {
+          event.preventDefault();
+          event.stopPropagation();
+        }
+        form.classList.add('was-validated');
+      }, false);
+    });
+  }, false);
+})();
+</script>
+{{< /example >}}
+
+### Browser defaults
+
+Not interested in custom validation feedback messages or writing JavaScript to change form behaviors? All good, you can use the browser defaults. Try submitting the form below. Depending on your browser and OS, you'll see a slightly different style of feedback.
+
+While these feedback styles cannot be styled with CSS, you can still customize the feedback text through JavaScript.
+
+{{< example >}}
+<form>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationDefault01">First name</label>
+      <input type="text" class="form-control" id="validationDefault01" value="Mark" required>
+    </div>
+    <div class="col-md-6 mb-3">
+      <label for="validationDefault02">Last name</label>
+      <input type="text" class="form-control" id="validationDefault02" value="Otto" required>
+    </div>
+  </div>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationDefault03">City</label>
+      <input type="text" class="form-control" id="validationDefault03" required>
+    </div>
+    <div class="col-md-3 mb-3">
+      <label for="validationDefault04">State</label>
+      <select class="custom-select" id="validationDefault04" required>
+        <option selected disabled value="">Choose...</option>
+        <option>...</option>
+      </select>
+    </div>
+    <div class="col-md-3 mb-3">
+      <label for="validationDefault05">Zip</label>
+      <input type="text" class="form-control" id="validationDefault05" required>
+    </div>
+  </div>
+  <div class="form-group">
+    <div class="form-check">
+      <input class="form-check-input" type="checkbox" value="" id="invalidCheck2" required>
+      <label class="form-check-label" for="invalidCheck2">
+        Agree to terms and conditions
+      </label>
+    </div>
+  </div>
+  <button class="btn btn-primary" type="submit">Submit form</button>
+</form>
+{{< /example >}}
+
+### Server side
+
+We recommend using client-side validation, but in case you require server-side validation, you can indicate invalid and valid form fields with `.is-invalid` and `.is-valid`. Note that `.invalid-feedback` is also supported with these classes.
+
+For invalid fields, ensure that the invalid feedback/error message is associated with the relevant form field using `aria-describedby`. This attribute allows more than one `id` to be referenced, in case the field already points to additional form text.
+
+{{< example >}}
+<form>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationServer01">First name</label>

+    Example invalid input group feedback
+  </div>
+</form>
+{{< /example >}}
+
+### Tooltips
+
+If your form layout allows it, you can swap the `.{valid|invalid}-feedback` classes for `.{valid|invalid}-tooltip` classes to display validation feedback in a styled tooltip. Be sure to have a parent with `position: relative` on it for tooltip positioning. In the example below, our column classes have this already, but your project may require an alternative setup.
+
+{{< example >}}
+<form class="needs-validation" novalidate>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationTooltip01">First name</label>
+      <input type="text" class="form-control" id="validationTooltip01" value="Mark" required>
+      <div class="valid-tooltip">
+        Looks good!
+      </div>
+    </div>
+    <div class="col-md-6 mb-3">
+      <label for="validationTooltip02">Last name</label>
+      <input type="text" class="form-control" id="validationTooltip02" value="Otto" required>
+      <div class="valid-tooltip">
+        Looks good!
+      </div>
+    </div>
+  </div>
+  <div class="form-row">
+    <div class="col-md-6 mb-3">
+      <label for="validationTooltip03">City</label>
+      <input type="text" class="form-control" id="validationTooltip03" required>
+      <div class="invalid-tooltip">
+        Please provide a valid city.
+      </div>
+    </div>
+    <div class="col-md-3 mb-3">
+      <label for="validationTooltip04">State</label>
+      <select class="custom-select" id="validationTooltip04" required>
+        <option selected disabled value="">Choose...</option>
+        <option>...</option>
+      </select>
+      <div class="invalid-tooltip">
+        Please select a valid state.
+      </div>
+    </div>
+    <div class="col-md-3 mb-3">
+      <label for="validationTooltip05">Zip</label>
+      <input type="text" class="form-control" id="validationTooltip05" required>
+      <div class="invalid-tooltip">
+        Please provide a valid zip.
+      </div>
+    </div>
+  </div>
+  <button class="btn btn-primary" type="submit">Submit form</button>
+</form>
+{{< /example >}}
+
+### Customizing
+
+Validation states can be customized via Sass with the `$form-validation-states` map. Located in our `_variables.scss` file, this Sass map is looped over to generate the default `valid`/`invalid` validation states. Included is a nested map for customizing each state's color and icon. While no other states are supported by browsers, those using custom styles can easily add more complex form feedback.
+
+Please note that we do not recommend customizing these values without also modifying the `form-validation-state` mixin.
+
+```scss
+// Sass map from `_variables.scss`
+// Override this and recompile your Sass to generate different states
+$form-validation-states: map-merge(
+  (
+    "valid": (
+      "color": $form-feedback-valid-color,
+      "icon": $form-feedback-icon-valid
+    ),
+    "invalid": (
+      "color": $form-feedback-invalid-color,
+      "icon": $form-feedback-icon-invalid
+    )
+  ),
+  $form-validation-states
+);
+
+// Loop from `_forms.scss`
+// Any modifications to the above Sass map will be reflected in your compiled
+// CSS via this loop.
+@each $state, $data in $form-validation-states {
+  @include form-validation-state($state, map-get($data, color), map-get($data, icon));
+}
+```
+
+### Input group validation
+
+To detect what elements need rounded corners inside an input group with validation, an input group requires an additional `.has-validation` class.
+
+```html
+<div class="input-group has-validation">
+  <div class="input-group-prepend">
+    <span class="input-group-text">@</span>
+  </div>
+  <input type="text" class="form-control" required>
+  <div class="invalid-feedback">
+    Please choose a username.
+  </div>
+</div>
+```
+
+<div class="bd-example bd-example-forms-input-group-workaround">
+  <div class="input-group has-validation">
+    <div class="input-group-prepend">
+      <span class="input-group-text">@</span>
+    </div>
+    <input type="text" class="form-control is-invalid" required>
+    <div class="invalid-feedback">
+      Please choose a username.
+    </div>
+  </div>
+</div>
+
+## Custom forms
+
+For even more customization and cross browser consistency, use our completely custom form elements to replace the browser defaults. They're built on top of semantic and accessible markup, so they're solid replacements for any default form control.
+
+### Checkboxes and radios
+
+Each checkbox and radio `<input>` and `<label>` pairing is wrapped in a `<div>` to create our custom control. Structurally, this is the same approach as our default `.form-check`.
+
+We use the sibling selector (`~`) for all our `<input>` states—like `:checked`—to properly style our custom form indicator. When combined with the `.custom-control-label` class, we can also style the text for each item based on the `<input>`'s state.
+
+We hide the default `<input>` with `opacity` and use the `.custom-control-label` to build a new custom form indicator in its place with `::before` and `::after`. Unfortunately we can't build a custom one from just the `<input>` because CSS's `content` doesn't work on that element.
+
+In the checked states, we use **base64 embedded SVG icons** from [Open Iconic](https://github.com/iconic/open-iconic). This provides us the best control for styling and positioning across browsers and devices.
+
+#### Checkboxes
+
+{{< example >}}
+<div class="custom-control custom-checkbox">
+  <input type="checkbox" class="custom-control-input" id="customCheck1">
+  <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
+</div>
+{{< /example >}}
+
+Custom checkboxes can also utilize the `:indeterminate` pseudo class when manually set via JavaScript (there is no available HTML attribute for specifying it).
+
+<div class="bd-example bd-example-indeterminate">
+  <div class="custom-control custom-checkbox">
+    <input type="checkbox" class="custom-control-input" id="customCheck2">
+    <label class="custom-control-label" for="customCheck2">Check this custom checkbox</label>
+  </div>
+</div>
+
+If you're using jQuery, something like this should suffice:
+
+```js
+$('.your-checkbox').prop('indeterminate', true)
+```
+
+#### Radios
+
+{{< example >}}
+<div class="custom-control custom-radio">
+  <input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
+  <label class="custom-control-label" for="customRadio1">Toggle this custom radio</label>
+</div>
+<div class="custom-control custom-radio">
+  <input type="radio" id="customRadio2" name="customRadio" class="custom-control-input">
+  <label class="custom-control-label" for="customRadio2">Or toggle this other custom radio</label>
+</div>
+{{< /example >}}
+
+#### Inline
+
+{{< example >}}
+<div class="custom-control custom-radio custom-control-inline">
+  <input type="radio" id="customRadioInline1" name="customRadioInline" class="custom-control-input">
+  <label class="custom-control-label" for="customRadioInline1">Toggle this custom radio</label>
+</div>
+<div class="custom-control custom-radio custom-control-inline">
+  <input type="radio" id="customRadioInline2" name="customRadioInline" class="custom-control-input">
+  <label class="custom-control-label" for="customRadioInline2">Or toggle this other custom radio</label>
+</div>
+{{< /example >}}
+
+#### Disabled
+
+Custom checkboxes and radios can also be disabled. Add the `disabled` boolean attribute to the `<input>` and the custom indicator and label description will be automatically styled.
+
+{{< example >}}
+<div class="custom-control custom-checkbox">
+  <input type="checkbox" class="custom-control-input" id="customCheckDisabled1" disabled>
+  <label class="custom-control-label" for="customCheckDisabled1">Check this custom checkbox</label>
+</div>
+
+<div class="custom-control custom-radio">
+  <input type="radio" name="radioDisabled" id="customRadioDisabled2" class="custom-control-input" disabled>
+  <label class="custom-control-label" for="customRadioDisabled2">Toggle this custom radio</label>
+</div>
+{{< /example >}}
+
+### Switches
+
+A switch has the markup of a custom checkbox but uses the `.custom-switch` class to render a toggle switch. Switches also support the `disabled` attribute.
+
+{{< example >}}
+<div class="custom-control custom-switch">
+  <input type="checkbox" class="custom-control-input" id="customSwitch1">
+  <label class="custom-control-label" for="customSwitch1">Toggle this switch element</label>
+</div>
+<div class="custom-control custom-switch">
+  <input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
+  <label class="custom-control-label" for="customSwitch2">Disabled switch element</label>
+</div>
+{{< /example >}}
+
+### Select menu
+
+Custom `<select>` menus need only a custom class, `.custom-select` to trigger the custom styles. Custom styles are limited to the `<select>`'s initial appearance and cannot modify the `<option>`s due to browser limitations.
+
+{{< example >}}
+<select class="custom-select">
+  <option selected>Open this select menu</option>
+  <option value="1">One</option>
+  <option value="2">Two</option>
+  <option value="3">Three</option>
+</select>
+{{< /example >}}
+
+You may also choose from small and large custom selects to match our similarly sized text inputs.
+
+{{< example >}}
+<select class="custom-select custom-select-lg mb-3">
+  <option selected>Open this select menu</option>
+  <option value="1">One</option>
+  <option value="2">Two</option>
+  <option value="3">Three</option>
+</select>
+
+<select class="custom-select custom-select-sm">
+  <option selected>Open this select menu</option>
+  <option value="1">One</option>
+  <option value="2">Two</option>
+  <option value="3">Three</option>
+</select>
+{{< /example >}}
+
+The `multiple` attribute is also supported:
+
+{{< example >}}
+<select class="custom-select" multiple>
+  <option selected>Open this select menu</option>
+  <option value="1">One</option>
+  <option value="2">Two</option>
+  <option value="3">Three</option>
+</select>
+{{< /example >}}
+
+As is the `size` attribute:
+
+{{< example >}}
+<select class="custom-select" size="3">
+  <option selected>Open this select menu</option>
+  <option value="1">One</option>
+  <option value="2">Two</option>
+  <option value="3">Three</option>
+</select>
+{{< /example >}}
+
+### Range
+
+Create custom `<input type="range">` controls with `.custom-range`. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only IE and Firefox support "filling" their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.
+
+{{< example >}}
+<label for="customRange1">Example range</label>
+<input type="range" class="custom-range" id="customRange1">
+{{< /example >}}
+
+Range inputs have implicit values for `min` and `max`—`0` and `100`, respectively. You may specify new values for those using the `min` and `max` attributes.
+
+{{< example >}}
+<label for="customRange2">Example range</label>
+<input type="range" class="custom-range" min="0" max="5" id="customRange2">
+{{< /example >}}
+
+By default, range inputs "snap" to integer values. To change this, you can specify a `step` value. In the example below, we double the number of steps by using `step="0.5"`.
+
+{{< example >}}
+<label for="customRange3">Example range</label>
+<input type="range" class="custom-range" min="0" max="5" step="0.5" id="customRange3">
+{{< /example >}}
+
+### File browser
+
+{{< callout info >}}
+The recommended plugin to animate custom file input: [bs-custom-file-input](https://www.npmjs.com/package/bs-custom-file-input), that's what we are using currently here in our docs.
+{{< /callout >}}
+
+The file input is the most gnarly of the bunch and requires additional JavaScript if you'd like to hook them up with functional *Choose file...* and selected file name text.
+
+{{< example >}}
+<div class="custom-file">
+  <input type="file" class="custom-file-input" id="customFile">
+  <label class="custom-file-label" for="customFile">Choose file</label>
+</div>
+{{< /example >}}
+
+We hide the default file `<input>` via `opacity` and instead style the `<label>`. The button is generated and positioned with `::after`. Lastly, we declare a `width` and `height` on the `<input>` for proper spacing for surrounding content.
+
+#### Translating or customizing the strings with SCSS
+
+The [`:lang()` pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:lang) is used to allow for translation of the "Browse" text into other languages. Override or add entries to the `$custom-file-text` Sass variable with the relevant [language tag](https://en.wikipedia.org/wiki/IETF_language_tag) and localized strings. The English strings can be customized the same way. For example, here's how one might add a Spanish translation (Spanish's language code is `es`):
+
+```scss
+$custom-file-text: (
+  en: "Browse",
+  es: "Elegir"
+);
+```
+
+Here's `lang(es)` in action on the custom file input for a Spanish translation:
+
+{{< example >}}
+<div class="custom-file">
+  <input type="file" class="custom-file-input" id="customFileLang" lang="es">
+  <label class="custom-file-label" for="customFileLang">Seleccionar Archivo</label>
+</div>
+{{< /example >}}
+
+You'll need to set the language of your document (or subtree thereof) correctly in order for the correct text to be shown. This can be done using [the `lang` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/lang) on the `<html>` element or the [`Content-Language` HTTP header](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.12), among other methods.
+
+#### Translating or customizing the strings with HTML
+
+Bootstrap also provides a way to translate the "Browse" text in HTML with the `data-browse` attribute which can be added to the custom input label (example in Dutch):
+
+{{< example >}}
+<div class="custom-file">
+  <input type="file" class="custom-file-input" id="customFileLangHTML">
+  <label class="custom-file-label" for="customFileLangHTML" data-browse="Bestand kiezen">Voeg je document toe</label>
+</div>
+{{< /example >}}

+title: Input group
+description: Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs.
+group: components
+toc: true
+---
+
+## Basic example
+
+Place one add-on or button on either side of an input. You may also place one on both sides of an input. Remember to place `<label>`s outside the input group.
+
+{{< example >}}
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <span class="input-group-text" id="basic-addon1">@</span>
+  </div>
+  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
+</div>
+
+<div class="input-group mb-3">
+  <input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
+  <div class="input-group-append">
+    <span class="input-group-text" id="basic-addon2">@example.com</span>
+  </div>
+</div>
+
+<label for="basic-url">Your vanity URL</label>
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
+  </div>
+  <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
+</div>
+
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <span class="input-group-text">$</span>
+  </div>
+  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
+  <div class="input-group-append">
+    <span class="input-group-text">.00</span>
+  </div>
+</div>
+
+<div class="input-group">
+  <div class="input-group-prepend">
+    <span class="input-group-text">With textarea</span>
+  </div>
+  <textarea class="form-control" aria-label="With textarea"></textarea>
+</div>
+{{< /example >}}
+
+## Wrapping
+
+Input groups wrap by default via `flex-wrap: wrap` in order to accommodate custom form field validation within an input group. You may disable this with `.flex-nowrap`.
+
+{{< example >}}
+<div class="input-group flex-nowrap">
+  <div class="input-group-prepend">
+    <span class="input-group-text" id="addon-wrapping">@</span>
+  </div>
+  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
+</div>
+{{< /example >}}
+
+## Sizing
+
+Add the relative form sizing classes to the `.input-group` itself and contents within will automatically resize—no need for repeating the form control size classes on each element.
+
+**Sizing on the individual input group elements isn't supported.**
+
+{{< example >}}
+<div class="input-group input-group-sm mb-3">
+  <div class="input-group-prepend">
+    <span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
+  </div>
+  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
+</div>
+
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <span class="input-group-text" id="inputGroup-sizing-default">Default</span>
+  </div>
+  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
+</div>
+
+<div class="input-group input-group-lg">
+  <div class="input-group-prepend">
+    <span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
+  </div>
+  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
+</div>
+{{< /example >}}
+
+## Checkboxes and radios
+
+Place any checkbox or radio option within an input group's addon instead of text.
+
+{{< example >}}
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <div class="input-group-text">
+      <input type="checkbox" aria-label="Checkbox for following text input">
+    </div>
+  </div>
+  <input type="text" class="form-control" aria-label="Text input with checkbox">
+</div>
+
+<div class="input-group">
+  <div class="input-group-prepend">
+    <div class="input-group-text">
+      <input type="radio" aria-label="Radio button for following text input">
+    </div>
+  </div>
+  <input type="text" class="form-control" aria-label="Text input with radio button">
+</div>
+{{< /example >}}
+
+## Multiple inputs
+
+While multiple `<input>`s are supported visually, validation styles are only available for input groups with a single `<input>`.
+
+{{< example >}}
+<div class="input-group">
+  <div class="input-group-prepend">
+    <span class="input-group-text">First and last name</span>
+  </div>
+  <input type="text" aria-label="First name" class="form-control">
+  <input type="text" aria-label="Last name" class="form-control">
+</div>
+{{< /example >}}
+
+## Multiple addons
+
+Multiple add-ons are supported and can be mixed with checkbox and radio input versions.
+
+{{< example >}}
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <span class="input-group-text">$</span>
+    <span class="input-group-text">0.00</span>
+  </div>
+  <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">
+</div>
+
+<div class="input-group">
+  <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">
+  <div class="input-group-append">
+    <span class="input-group-text">$</span>
+    <span class="input-group-text">0.00</span>
+  </div>
+</div>
+{{< /example >}}
+
+## Button addons
+
+{{< example >}}
+<div class="input-group mb-3">
+  <div class="input-group-prepend">
+    <button class="btn btn-outline-secondary" type="button" id="button-addon1">Button</button>

+## Accessibility
+
+Ensure that all form controls have an appropriate accessible name so that their purpose can be conveyed to users of assistive technologies. The simplest way to achieve this is to use a `<label>` element, or—in the case of buttons—to include sufficiently descriptive text as part of the `<button>...</button>` content.
+
+For situations where it's not possible to include a visible `<label>` or appropriate text content, there are alternative ways of still providing an accessible name, such as:
+
+- `<label>` elements hidden using the `.sr-only` class
+- Pointing to an existing element that can act as a label using `aria-labelledby`
+- Providing a `title` attribute
+- Explicitly setting the accessible name on an element using `aria-label`
+
+If none of these are present, assistive technologies may resort to using the `placeholder` attribute as a fallback for the accessible name on `<input>` and `<textarea>` elements. The examples in this section provide a few suggested, case-specific approaches.
+
+While using visually hidden content (`.sr-only`, `aria-label`, and even `placeholder` content, which disappears once a form field has content) will benefit assistive technology users, a lack of visible label text may still be problematic for certain users. Some form of visible label is generally the best approach, both for accessibility and usability.

+title: Jumbotron
+description: Lightweight, flexible component for showcasing hero unit style content.
+group: components
+---
+
+A lightweight, flexible component that can optionally extend the entire viewport to showcase key marketing messages on your site.
+
+{{< example >}}
+<div class="jumbotron">
+  <h1 class="display-4">Hello, world!</h1>
+  <p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
+  <hr class="my-4">
+  <p>It uses utility classes for typography and spacing to space content out within the larger container.</p>
+  <a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a>
+</div>
+{{< /example >}}
+
+To make the jumbotron full width, and without rounded corners, add the `.jumbotron-fluid` modifier class and add a `.container` or `.container-fluid` within.
+
+{{< example >}}
+<div class="jumbotron jumbotron-fluid">

+title: List group
+description: List groups are a flexible and powerful component for displaying a series of content. Modify and extend them to support just about any content within.
+group: components
+toc: true
+---
+
+## Basic example
+
+The most basic list group is an unordered list with list items and the proper classes. Build upon it with the options that follow, or with your own CSS as needed.
+
+{{< example >}}
+<ul class="list-group">
+  <li class="list-group-item">An item</li>
+  <li class="list-group-item">A second item</li>
+  <li class="list-group-item">A third item</li>
+  <li class="list-group-item">A fourth item</li>
+  <li class="list-group-item">And a fifth one</li>
+</ul>
+{{< /example >}}
+
+## Active items
+
+Add `.active` to a `.list-group-item` to indicate the current active selection.
+
+{{< example >}}
+<ul class="list-group">
+  <li class="list-group-item active" aria-current="true">An active item</li>
+  <li class="list-group-item">A second item</li>
+  <li class="list-group-item">A third item</li>
+  <li class="list-group-item">A fourth item</li>
+  <li class="list-group-item">And a fifth one</li>
+</ul>
+{{< /example >}}
+
+## Disabled items
+
+Add `.disabled` to a `.list-group-item` to make it _appear_ disabled. Note that some elements with `.disabled` will also require custom JavaScript to fully disable their click events (e.g., links).
+
+{{< example >}}
+<ul class="list-group">
+  <li class="list-group-item disabled" aria-disabled="true">A disabled item</li>
+  <li class="list-group-item">A second item</li>
+  <li class="list-group-item">A third item</li>
+  <li class="list-group-item">A fourth item</li>
+  <li class="list-group-item">And a fifth one</li>
+</ul>
+{{< /example >}}
+
+## Links and buttons
+
+Use `<a>`s or `<button>`s to create _actionable_ list group items with hover, disabled, and active states by adding `.list-group-item-action`. We separate these pseudo-classes to ensure list groups made of non-interactive elements (like `<li>`s or `<div>`s) don't provide a click or tap affordance.
+
+Be sure to **not use the standard `.btn` classes here**.
+
+{{< example >}}
+<div class="list-group">
+  <a href="#" class="list-group-item list-group-item-action active" aria-current="true">
+    The current link item
+  </a>
+  <a href="#" class="list-group-item list-group-item-action">A second link item</a>
+  <a href="#" class="list-group-item list-group-item-action">A third link item</a>
+  <a href="#" class="list-group-item list-group-item-action">A fourth link item</a>
+  <a href="#" class="list-group-item list-group-item-action disabled" tabindex="-1" aria-disabled="true">A disabled link item</a>
+</div>
+{{< /example >}}
+
+With `<button>`s, you can also make use of the `disabled` attribute instead of the `.disabled` class. Sadly, `<a>`s don't support the disabled attribute.
+
+{{< example >}}
+<div class="list-group">
+  <button type="button" class="list-group-item list-group-item-action active" aria-current="true">
+    The current button
+  </button>
+  <button type="button" class="list-group-item list-group-item-action">A second item</button>
+  <button type="button" class="list-group-item list-group-item-action">A third button item</button>
+  <button type="button" class="list-group-item list-group-item-action">A fourth button item</button>
+  <button type="button" class="list-group-item list-group-item-action" disabled>A disabled button item</button>
+</div>
+{{< /example >}}
+
+## Flush
+
+Add `.list-group-flush` to remove some borders and rounded corners to render list group items edge-to-edge in a parent container (e.g., cards).
+
+{{< example >}}
+<ul class="list-group list-group-flush">
+  <li class="list-group-item">An item</li>
+  <li class="list-group-item">A second item</li>
+  <li class="list-group-item">A third item</li>
+  <li class="list-group-item">A fourth item</li>
+  <li class="list-group-item">And a fifth one</li>
+</ul>
+{{< /example >}}
+
+## Horizontal
+
+Add `.list-group-horizontal` to change the layout of list group items from vertical to horizontal across all breakpoints. Alternatively, choose a responsive variant `.list-group-horizontal-{sm|md|lg|xl}` to make a list group horizontal starting at that breakpoint's `min-width`. Currently **horizontal list groups cannot be combined with flush list groups.**
+
+**ProTip:** Want equal-width list group items when horizontal? Add `.flex-fill` to each list group item.
+
+{{< example >}}
+{{< list-group.inline >}}
+{{- range $.Site.Data.breakpoints }}
+<ul class="list-group list-group-horizontal{{ .abbr }}">
+  <li class="list-group-item">An item</li>
+  <li class="list-group-item">A second item</li>
+  <li class="list-group-item">A third item</li>
+</ul>
+{{- end -}}
+{{< /list-group.inline >}}
+{{< /example >}}
+
+## Contextual classes
+
+Use contextual classes to style list items with a stateful background and color.
+
+{{< example >}}
+<ul class="list-group">
+  <li class="list-group-item">A simple default list group item</li>
+{{< list.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+  <li class="list-group-item list-group-item-{{ .name }}">A simple {{ .name }} list group item</li>
+{{- end -}}
+{{< /list.inline >}}
+</ul>
+{{< /example >}}
+
+Contextual classes also work with `.list-group-item-action`. Note the addition of the hover styles here not present in the previous example. Also supported is the `.active` state; apply it to indicate an active selection on a contextual list group item.
+
+{{< example >}}
+<div class="list-group">
+  <a href="#" class="list-group-item list-group-item-action">A simple default list group item</a>
+{{< list.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+  <a href="#" class="list-group-item list-group-item-action list-group-item-{{ .name }}">A simple {{ .name }} list group item</a>
+{{- end -}}
+{{< /list.inline >}}
+</div>
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+## With badges
+
+Add badges to any list group item to show unread counts, activity, and more with the help of some [utilities]({{< docsref "/utilities/flex" >}}).
+
+{{< example >}}
+<ul class="list-group">
+  <li class="list-group-item d-flex justify-content-between align-items-center">
+    A list item
+    <span class="badge badge-primary badge-pill">14</span>
+  </li>
+  <li class="list-group-item d-flex justify-content-between align-items-center">
+    A second list item
+    <span class="badge badge-primary badge-pill">2</span>
+  </li>
+  <li class="list-group-item d-flex justify-content-between align-items-center">
+    A third list item
+    <span class="badge badge-primary badge-pill">1</span>
+  </li>
+</ul>
+{{< /example >}}
+
+## Custom content
+
+Add nearly any HTML within, even for linked list groups like the one below, with the help of [flexbox utilities]({{< docsref "/utilities/flex" >}}).
+
+{{< example >}}
+<div class="list-group">
+  <a href="#" class="list-group-item list-group-item-action active">
+    <div class="d-flex w-100 justify-content-between">
+      <h5 class="mb-1">List group item heading</h5>
+      <small>3 days ago</small>
+    </div>
+    <p class="mb-1">Some placeholder content in a paragraph.</p>
+    <small>And some small print.</small>
+  </a>
+  <a href="#" class="list-group-item list-group-item-action">
+    <div class="d-flex w-100 justify-content-between">
+      <h5 class="mb-1">List group item heading</h5>
+      <small class="text-muted">3 days ago</small>
+    </div>
+    <p class="mb-1">Some placeholder content in a paragraph.</p>
+    <small class="text-muted">And some muted small print.</small>
+  </a>
+  <a href="#" class="list-group-item list-group-item-action">
+    <div class="d-flex w-100 justify-content-between">
+      <h5 class="mb-1">List group item heading</h5>
+      <small class="text-muted">3 days ago</small>
+    </div>
+    <p class="mb-1">Some placeholder content in a paragraph.</p>
+    <small class="text-muted">And some muted small print.</small>
+  </a>
+</div>
+{{< /example >}}
+
+## JavaScript behavior
+
+Use the tab JavaScript plugin—include it individually or through the compiled `bootstrap.js` file—to extend our list group to create tabbable panes of local content.

+
+### Using data attributes
+
+You can activate a list group navigation without writing any JavaScript by simply specifying `data-toggle="list"` or on an element. Use these data attributes on `.list-group-item`.
+
+```html
+<div role="tabpanel">
+  <!-- List group -->
+  <div class="list-group" id="myList" role="tablist">
+    <a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
+    <a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
+    <a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
+    <a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
+  </div>
+
+  <!-- Tab panes -->
+  <div class="tab-content">
+    <div class="tab-pane active" id="home" role="tabpanel">...</div>
+    <div class="tab-pane" id="profile" role="tabpanel">...</div>
+    <div class="tab-pane" id="messages" role="tabpanel">...</div>
+    <div class="tab-pane" id="settings" role="tabpanel">...</div>
+  </div>
+</div>
+```
+
+### Via JavaScript
+
+Enable tabbable list item via JavaScript (each list item needs to be activated individually):
+
+```js
+$('#myList a').on('click', function (event) {
+  event.preventDefault()
+  $(this).tab('show')
+})
+```
+
+You can activate individual list item in several ways:
+
+```js
+$('#myList a[href="#profile"]').tab('show') // Select tab by name
+$('#myList a:first-child').tab('show') // Select first tab
+$('#myList a:last-child').tab('show') // Select last tab
+$('#myList a:nth-child(3)').tab('show') // Select third tab
+```
+
+### Fade effect

+To make tabs panel fade in, add `.fade` to each `.tab-pane`. The first tab pane must also have `.show` to make the initial content visible.
+
+```html
+<div class="tab-content">
+  <div class="tab-pane fade show active" id="home" role="tabpanel">...</div>
+  <div class="tab-pane fade" id="profile" role="tabpanel">...</div>
+  <div class="tab-pane fade" id="messages" role="tabpanel">...</div>
+  <div class="tab-pane fade" id="settings" role="tabpanel">...</div>
+</div>
+```
+
+### Methods
+
+#### $().tab
+
+Activates a list item element and content container. Tab should have either a `data-target` or an `href` targeting a container node in the DOM.
+
+```html
+<div class="list-group" id="myList" role="tablist">
+  <a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
+</div>
+
+<div class="tab-content">
+  <div class="tab-pane active" id="home" role="tabpanel">...</div>
+  <div class="tab-pane" id="profile" role="tabpanel">...</div>
+  <div class="tab-pane" id="messages" role="tabpanel">...</div>
+  <div class="tab-pane" id="settings" role="tabpanel">...</div>
+</div>
+
+<script>
+  $(function () {
+    $('#myList a:last-child').tab('show')
+  })
+</script>
+```
+
+#### .tab('show')
+
+Selects the given list item and shows its associated pane. Any other list item that was previously selected becomes unselected and its associated pane is hidden. **Returns to the caller before the tab pane has actually been shown** (for example, before the `shown.bs.tab` event occurs).
+
+```js
+$('#someListItem').tab('show')
+```
+
+### Events
+
+When showing a new tab, the events fire in the following order:
+
+1. `hide.bs.tab` (on the current active tab)
+2. `show.bs.tab` (on the to-be-shown tab)
+3. `hidden.bs.tab` (on the previous active tab, the same one as for the `hide.bs.tab` event)
+4. `shown.bs.tab` (on the newly-active just-shown tab, the same one as for the `show.bs.tab` event)
+
+If no tab was already active, the `hide.bs.tab` and `hidden.bs.tab` events will not be fired.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 150px;">Event type</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>show.bs.tab</td>
+      <td>This event fires on tab show, but before the new tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
+    </tr>
+    <tr>
+      <td>shown.bs.tab</td>
+      <td>This event fires on tab show after a tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
+    </tr>
+    <tr>
+      <td>hide.bs.tab</td>
+      <td>This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the current active tab and the new soon-to-be-active tab, respectively.</td>
+    </tr>
+    <tr>
+      <td>hidden.bs.tab</td>
+      <td>This event fires after a new tab is shown (and thus the previous active tab is hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the previous active tab and the new active tab, respectively.</td>
+    </tr>
+  </tbody>
+</table>
+
+```js
+$('a[data-toggle="list"]').on('shown.bs.tab', function (event) {
+  event.target // newly activated tab
+  event.relatedTarget // previous active tab
+})

+title: Media object
+description: Documentation and examples for Bootstrap's media object to construct highly repetitive components like blog comments, tweets, and the like.
+group: components
+toc: true
+---
+
+## Example
+
+The [media object](http://www.stubbornella.org/content/2010/06/25/the-media-object-saves-hundreds-of-lines-of-code/) helps build complex and repetitive components where some media is positioned alongside content that doesn't wrap around said media. Plus, it does this with only two required classes thanks to flexbox.
+
+Below is an example of a single media object. Only two classes are required—the wrapping `.media` and the `.media-body` around your content. Optional padding and margin can be controlled through [spacing utilities]({{< docsref "/utilities/spacing" >}}).
+
+{{< example >}}
+<div class="media">
+  {{< placeholder width="64" height="64" class="mr-3" >}}
+  <div class="media-body">
+    <h5 class="mt-0">Media heading</h5>
+    <p>Will you do the same for me? It's time to face the music I'm no longer your muse. Heard it's beautiful, be the judge and my girls gonna take a vote. I can feel a phoenix inside of me. Heaven is jealous of our love, angels are crying from up above. Yeah, you take me to utopia.</p>
+  </div>
+</div>
+{{< /example >}}
+
+{{< callout warning >}}
+##### Flexbug #12: Inline elements aren't treated as flex items
+
+Internet Explorer 10-11 do not render inline elements like links or images (or `::before` and `::after` pseudo-elements) as flex items. The only workaround is to set a non-inline `display` value (e.g., `block`, `inline-block`, or `flex`). We suggest using `.d-flex`, one of our [display utilities]({{< docsref "/utilities/display" >}}), as an easy fix.
+
+**Source:** [Flexbugs on GitHub](https://github.com/philipwalton/flexbugs#flexbug-12)
+{{< /callout >}}
+
+## Nesting
+
+Media objects can be infinitely nested, though we suggest you stop at some point. Place nested `.media` within the `.media-body` of a parent media object.
+
+{{< example >}}
+<div class="media">
+  {{< placeholder width="64" height="64" class="mr-3" >}}
+  <div class="media-body">
+    <h5 class="mt-0">Media heading</h5>
+    <p>Standing on the frontline when the bombs start to fall. Heaven is jealous of our love, angels are crying from up above. Can't replace you with a million rings. Boy, when you're with me I'll give you a taste. There’s no going back. Before you met me I was alright but things were kinda heavy. Heavy is the head that wears the crown.</p>
+
+    <div class="media mt-3">
+      <a class="mr-3" href="#">
+        {{< placeholder width="64" height="64" >}}
+      </a>
+      <div class="media-body">
+        <h5 class="mt-0">Media heading</h5>
+        <p>Greetings loved ones let's take a journey. Yes, we make angels cry, raining down on earth from up above. Give you something good to celebrate. I used to bite my tongue and hold my breath. I'm ma get your heart racing in my skin-tight jeans. As I march alone to a different beat. Summer after high school when we first met. You're so hypnotizing, could you be the devil? Could you be an angel? It's time to bring out the big balloons. Thought that I was the exception. Bikinis, zucchinis, Martinis, no weenies.</p>
+      </div>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+## Alignment
+
+Media in a media object can be aligned with flexbox utilities to the top (default), middle, or end of your `.media-body` content.
+
+{{< example >}}
+<div class="media">
+  {{< placeholder width="64" height="64" class="align-self-start mr-3" >}}
+  <div class="media-body">
+    <h5 class="mt-0">Top-aligned media</h5>
+    <p>I’m gon’ put her in a coma. You give a hundred reasons why, and you say you're really gonna try. So I sat quietly, agreed politely. Suiting up for my crowning battle. And on my 18th Birthday we got matching tattoos. So très chic, yeah, she's a classic. I am ready for the road less traveled.</p>
+    <p>I'm walking on air (tonight). But down to earth. You're original, cannot be replaced. But in another life I would be your girl. We drove to Cali and got drunk on the beach. We can dance, until we die, you and I, will be young forever. Saw you downtown singing the Blues.</p>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="media">
+  {{< placeholder width="64" height="64" class="align-self-center mr-3" >}}
+  <div class="media-body">
+    <h5 class="mt-0">Center-aligned media</h5>
+    <p>She'll turn cold as a freezer. At the eh-end of it all. Stinging like a bee I earned my stripes. Bikinis, zucchinis, Martinis, no weenies. I hope you got a healthy appetite. We can dance, until we die, you and I, will be young forever. We're living the life. We're doing it right. Word on the street, you got somethin' to show me, me.</p>
+    <p class="mb-0">Wanna see the show in 3D, a movie. They say, be afraid you're not like the others, futuristic lover. Open up your heart. So I sat quietly, agreed politely. Last Friday night. Yeah, you're lucky if you're on her plane. I'll be your gift, give you something good to celebrate.</p>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="media">
+  {{< placeholder width="64" height="64" class="align-self-end mr-3" >}}
+  <div class="media-body">
+    <h5 class="mt-0">Bottom-aligned media</h5>
+    <p>Come on, let your colours burst. I can feel this light that's inside of me. All night they're playing, your song. From Tokyo to Mexico, to Rio. There’s no going back. But down to earth. Magical, colorful, Mr. Mystery, ee. Different DNA, they don't understand you.</p>
+    <p class="mb-0">But down to earth. She's got that, je ne sais quoi, you know it. I can see the writing on the wall. The boys break their necks try'na to creep a little sneak peek. Take me, ta-ta-take me. Open up your heart. Thought that I was the exception. Boom, boom, boom. Venice beach and Palm Springs, summertime is everything. Bring the beat back. (This is how we do)</p>
+  </div>
+</div>
+{{< /example >}}
+
+## Order
+
+Change the order of content in media objects by modifying the HTML itself, or by adding some custom flexbox CSS to set the `order` property (to an integer of your choosing).
+
+{{< example >}}
+<div class="media">
+  <div class="media-body">
+    <h5 class="mt-0 mb-1">Media object</h5>
+    <p>I know there will be sacrifice but that's the price. Are you brave enough to let me see your peacock? Be your teenage dream tonight. Uh-huh, I see you. There’s no going back. Yeah, we maxed our credit cards and got kicked out of the bar. So let me get you in your birthday suit. You may fall in love when you meet her. Had the world in the palm of your hands. Don't let the greatness get you down, oh, oh yeah. Now we talking astrology, getting our nails did, all Japanese-y. Make me your Aphrodite.</p>
+  </div>
+  {{< placeholder width="64" height="64" class="ml-3" >}}
+</div>
+{{< /example >}}
+
+## Media list
+
+Because the media object has so few structural requirements, you can also use these classes on list HTML elements. On your `<ul>` or `<ol>`, add the `.list-unstyled` to remove any browser default list styles, and then apply `.media` to your `<li>`s. As always, use spacing utilities wherever needed to fine tune.
+
+{{< example >}}
+<ul class="list-unstyled">
+  <li class="media">
+    {{< placeholder width="64" height="64" class="mr-3" >}}
+    <div class="media-body">
+      <h5 class="mt-0 mb-1">List-based media object</h5>
+      <p>All my girls vintage Chanel baby. So you can have your cake. Tonight, tonight, tonight, I'm walking on air. Slowly swallowing down my fear, yeah yeah. Growing fast into a bolt of lightning. So hot and heavy, 'Til dawn. That fairy tale ending with a knight in shining armor. Heavy is the head that wears the crown.</p>
+    </div>
+  </li>
+  <li class="media my-4">
+    {{< placeholder width="64" height="64" class="mr-3" >}}
+    <div class="media-body">
+      <h5 class="mt-0 mb-1">List-based media object</h5>
+      <p>Maybe a reason why all the doors are closed. Cause once you’re mine, once you’re mine. Be your teenage dream tonight. Heavy is the head that wears the crown. It's not even a holiday, nothing to celebrate. A perfect storm, perfect storm.</p>
+    </div>
+  </li>
+  <li class="media">
+    {{< placeholder width="64" height="64" class="mr-3" >}}
+    <div class="media-body">
+      <h5 class="mt-0 mb-1">List-based media object</h5>
+      <p>Are you brave enough to let me see your peacock? There’s no going back. This is the last time you say, after the last line you break. At the eh-end of it all.</p>
+    </div>
+  </li>
+</ul>
+{{< /example >}}

+description: Use Bootstrap's JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.
+group: components
+toc: true
+---
+
+## How it works
+
+Before getting started with Bootstrap's modal component, be sure to read the following as our menu options have recently changed.
+
+- Modals are built with HTML, CSS, and JavaScript. They're positioned over everything else in the document and remove scroll from the `<body>` so that modal content scrolls instead.
+- Clicking on the modal "backdrop" will automatically close the modal.
+- Bootstrap only supports one modal window at a time. Nested modals aren't supported as we believe them to be poor user experiences.
+- Modals use `position: fixed`, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You'll likely run into issues when nesting a `.modal` within another fixed element.
+- Once again, due to `position: fixed`, there are some caveats with using modals on mobile devices. [See our browser support docs]({{< docsref "/getting-started/browsers-devices#modals-and-dropdowns-on-mobile" >}}) for details.
+- Due to how HTML5 defines its semantics, [the `autofocus` HTML attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attr-autofocus) has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:
+
+```js
+$('#myModal').on('shown.bs.modal', function () {
+  $('#myInput').trigger('focus')
+})
+```

+
+## Examples
+
+### Modal components
+
+Below is a _static_ modal example (meaning its `position` and `display` have been overridden). Included are the modal header, modal body (required for `padding`), and modal footer (optional). We ask that you include modal headers with dismiss actions whenever possible, or provide another explicit dismiss action.
+
+<div class="bd-example bd-example-modal">
+  <div class="modal" tabindex="-1">
+    <div class="modal-dialog">
+      <div class="modal-content">
+        <div class="modal-header">
+          <h5 class="modal-title">Modal title</h5>
+          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
+            <span aria-hidden="true">&times;</span>
+          </button>
+        </div>
+        <div class="modal-body">

+    </div>
+  </div>

+
+### Scrolling long content
+
+When modals become too long for the user's viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.
+
+<div class="modal fade" id="exampleModalLong" tabindex="-1" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
+  <div class="modal-dialog">
+    <div class="modal-content">

+          <span aria-hidden="true">&times;</span>
+        </button>
+      </div>
+      <div class="modal-body">
+        <p>What follows is just some placeholder text for this modal dialog. Sipping on Rosé, Silver Lake sun, coming up all lazy. It’s in the palm of your hand now baby. So we hit the boulevard. So make a wish, I'll make it like your birthday everyday. Do you ever feel already buried deep six feet under? It's time to bring out the big balloons. You could've been the greatest. Passport stamps, she's cosmopolitan. Your kiss is cosmic, every move is magic.</p>
+        <p>We're living the life. We're doing it right. Open up your heart. I was tryna hit it and quit it. Her love is like a drug. Always leaves a trail of stardust.

+
+### Varying modal content
+
+Have a bunch of buttons that all trigger the same modal with slightly different contents? Use `event.relatedTarget` and [HTML `data-*` attributes](https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes) (possibly [via jQuery](https://api.jquery.com/data/)) to vary the contents of the modal depending on which button was clicked.
+
+Below is a live demo followed by example HTML and JavaScript. For more information, [read the modal events docs](#events) for details on `relatedTarget`.
+
+{{< example >}}
+<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button>
+<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@fat">Open modal for @fat</button>
+<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@getbootstrap">Open modal for @getbootstrap</button>
+
+<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
+  <div class="modal-dialog">
+    <div class="modal-content">
+      <div class="modal-header">
+        <h5 class="modal-title" id="exampleModalLabel">New message</h5>
+        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
+          <span aria-hidden="true">&times;</span>
+        </button>
+      </div>
+      <div class="modal-body">
+        <form>
+          <div class="form-group">
+            <label for="recipient-name" class="col-form-label">Recipient:</label>
+            <input type="text" class="form-control" id="recipient-name">
+          </div>
+          <div class="form-group">
+            <label for="message-text" class="col-form-label">Message:</label>
+            <textarea class="form-control" id="message-text"></textarea>
+          </div>
+        </form>
+      </div>
+      <div class="modal-footer">
+        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
+        <button type="button" class="btn btn-primary">Send message</button>
+      </div>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+```js
+$('#exampleModal').on('show.bs.modal', function (event) {
+  var button = $(event.relatedTarget) // Button that triggered the modal
+  var recipient = button.data('whatever') // Extract info from data-* attributes
+  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
+  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
+  var modal = $(this)
+  modal.find('.modal-title').text('New message to ' + recipient)
+  modal.find('.modal-body input').val(recipient)
+})
+```
+
+### Change animation
+
+The `$modal-fade-transform` variable determines the transform state of `.modal-dialog` before the modal fade-in animation, the `$modal-show-transform` variable determines the transform of `.modal-dialog` at the end of the modal fade-in animation.
+
+If you want for example a zoom-in animation, you can set `$modal-fade-transform: scale(.8)`.
+
+### Remove animation
+
+For modals that simply appear rather than fade in to view, remove the `.fade` class from your modal markup.
+
+```html
+<div class="modal" tabindex="-1" aria-labelledby="..." aria-hidden="true">
+  ...
+</div>
+```
+
+### Dynamic heights
+
+If the height of a modal changes while it is open, you should call `$('#myModal').modal('handleUpdate')` to readjust the modal's position in case a scrollbar appears.
+
+### Accessibility
+
+Be sure to add `aria-labelledby="..."`, referencing the modal title, to `.modal`. Additionally, you may give a description of your modal dialog with `aria-describedby` on `.modal`. Note that you don't need to add `role="dialog"` since we already add it via JavaScript.
+
+### Embedding YouTube videos
+
+Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. [See this helpful Stack Overflow post](https://stackoverflow.com/questions/18622508/bootstrap-3-and-youtube-in-modal) for more information.
+
+## Optional sizes
+
+Modals have three optional sizes, available via modifier classes to be placed on a `.modal-dialog`. These sizes kick in at certain breakpoints to avoid horizontal scrollbars on narrower viewports.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th>Size</th>
+      <th>Class</th>
+      <th>Modal max-width</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>Small</td>
+      <td><code>.modal-sm</code></td>
+      <td><code>300px</code></td>
+    </tr>
+    <tr>
+      <td>Default</td>
+      <td class="text-muted">None</td>
+      <td><code>500px</code></td>
+    </tr>
+    <tr>
+      <td>Large</td>
+      <td><code>.modal-lg</code></td>
+      <td><code>800px</code></td>
+    </tr>
+    <tr>
+      <td>Extra large</td>
+      <td><code>.modal-xl</code></td>
+      <td><code>1140px</code></td>
+    </tr>
+  </tbody>
+</table>
+
+Our default modal without modifier class constitutes the "medium" size modal.
+
+<div class="bd-example">
+  <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalXl">Extra large modal</button>

+</div>
+
+## Usage
+
+The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds `.modal-open` to the `<body>` to override default scrolling behavior and generates a `.modal-backdrop` to provide a click area for dismissing shown modals when clicking outside the modal.
+
+### Via data attributes
+
+Activate a modal without writing JavaScript. Set `data-toggle="modal"` on a controller element, like a button, along with a `data-target="#foo"` or `href="#foo"` to target a specific modal to toggle.
+
+```html
+<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
+```
+
+### Via JavaScript
+
+Call a modal with id `myModal` with a single line of JavaScript:
+
+```js
+$('#myModal').modal(options)
+```
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-backdrop=""`.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 50px;">Type</th>
+      <th style="width: 50px;">Default</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>backdrop</td>
+      <td>boolean or the string <code>'static'</code></td>
+      <td>true</td>
+      <td>Includes a modal-backdrop element. Alternatively, specify <code>static</code> for a backdrop which doesn't close the modal on click.</td>
+    </tr>
+    <tr>
+      <td>keyboard</td>
+      <td>boolean</td>
+      <td>true</td>
+      <td>Closes the modal when escape key is pressed</td>
+    </tr>
+    <tr>
+      <td>focus</td>
+      <td>boolean</td>
+      <td>true</td>
+      <td>Puts the focus on the modal when initialized.</td>
+    </tr>
+    <tr>
+      <td>show</td>
+      <td>boolean</td>
+      <td>true</td>
+      <td>Shows the modal when initialized.</td>
+    </tr>
+  </tbody>
+</table>
+
+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### `.modal(options)`
+
+Activates your content as a modal. Accepts an optional options `object`.
+
+```js
+$('#myModal').modal({
+  keyboard: false
+})
+```
+
+#### `.modal('toggle')`
+
+Manually toggles a modal. **Returns to the caller before the modal has actually been shown or hidden** (i.e. before the `shown.bs.modal` or `hidden.bs.modal` event occurs).
+
+```js
+$('#myModal').modal('toggle')
+```
+
+#### `.modal('show')`
+
+Manually opens a modal. **Returns to the caller before the modal has actually been shown** (i.e. before the `shown.bs.modal` event occurs).
+
+```js
+$('#myModal').modal('show')
+```
+
+#### `.modal('hide')`
+
+Manually hides a modal. **Returns to the caller before the modal has actually been hidden** (i.e. before the `hidden.bs.modal` event occurs).
+
+```js
+$('#myModal').modal('hide')
+```
+
+#### `.modal('handleUpdate')`
+
+Manually readjust the modal's position if the height of a modal changes while it is open (i.e. in case a scrollbar appears).
+
+```js
+$('#myModal').modal('handleUpdate')
+```
+
+#### `.modal('dispose')`
+
+Destroys an element's modal.
+
+### Events
+
+Bootstrap's modal class exposes a few events for hooking into modal functionality. All modal events are fired at the modal itself (i.e. at the `<div class="modal">`).
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 150px;">Event Type</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>show.bs.modal</td>
+      <td>This event fires immediately when the <code>show</code> instance method is called. If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
+    </tr>
+    <tr>
+      <td>shown.bs.modal</td>
+      <td>This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
+    </tr>
+    <tr>
+      <td>hide.bs.modal</td>
+      <td>This event is fired immediately when the <code>hide</code> instance method has been called.</td>
+    </tr>
+    <tr>
+      <td>hidden.bs.modal</td>
+      <td>This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).</td>
+    </tr>
+    <tr>
+      <td>hidePrevented.bs.modal</td>
+      <td>This event is fired when the modal is shown, its backdrop is <code>static</code> and a click outside the modal or an escape key press is performed with the keyboard option or <code>data-keyboard</code> set to <code>false</code>.</td>
+    </tr>
+  </tbody>
+</table>
+
+```js
+$('#myModal').on('hidden.bs.modal', function (event) {
+  // do something...
+})
+```

+toc: true
+---
+
+## How it works
+
+Here's what you need to know before getting started with the navbar:
+
+- Navbars require a wrapping `.navbar` with `.navbar-expand{-sm|-md|-lg|-xl}` for responsive collapsing and [color scheme](#color-schemes) classes.
+- Navbars and their contents are fluid by default. Use [optional containers](#containers) to limit their horizontal width.
+- Use our [spacing]({{< docsref "/utilities/spacing" >}}) and [flex]({{< docsref "/utilities/flex" >}}) utility classes for controlling spacing and alignment within navbars.
+- Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.
+- Navbars are hidden by default when printing. Force them to be printed by adding `.d-print` to the `.navbar`. See the [display]({{< docsref "/utilities/display" >}}) utility class.
+- Ensure accessibility by using a `<nav>` element or, if using a more generic element such as a `<div>`, add a `role="navigation"` to every navbar to explicitly identify it as a landmark region for users of assistive technologies.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+## Supported content
+
+Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:
+
+- `.navbar-brand` for your company, product, or project name.
+- `.navbar-nav` for a full-height and lightweight navigation (including support for dropdowns).
+- `.navbar-toggler` for use with our collapse plugin and other [navigation toggling](#responsive-behaviors) behaviors.
+- `.form-inline` for any form controls and actions.
+- `.navbar-text` for adding vertically centered strings of text.
+- `.collapse.navbar-collapse` for grouping and hiding navbar contents by a parent breakpoint.
+
+Here's an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at the `lg` (large) breakpoint.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+
+  <div class="collapse navbar-collapse" id="navbarSupportedContent">
+    <ul class="navbar-nav mr-auto">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item dropdown">
+        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+          Dropdown
+        </a>
+        <div class="dropdown-menu" aria-labelledby="navbarDropdown">
+          <a class="dropdown-item" href="#">Action</a>
+          <a class="dropdown-item" href="#">Another action</a>
+          <div class="dropdown-divider"></div>
+          <a class="dropdown-item" href="#">Something else here</a>
+        </div>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+    <form class="form-inline my-2 my-lg-0">
+      <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
+      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
+    </form>
+  </div>
+</nav>
+{{< /example >}}
+
+This example uses [color]({{< docsref "/utilities/colors" >}}) (`bg-light`) and [spacing]({{< docsref "/utilities/spacing" >}}) (`my-2`, `my-lg-0`, `mr-sm-0`, `my-sm-0`) utility classes.
+
+### Brand
+
+The `.navbar-brand` can be applied to most elements, but an anchor works best, as some elements might require utility classes or custom styles.
+
+{{< example >}}
+<!-- As a link -->
+<nav class="navbar navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar</a>
+</nav>
+
+<!-- As a heading -->
+<nav class="navbar navbar-light bg-light">
+  <span class="navbar-brand mb-0 h1">Navbar</span>
+</nav>
+{{< /example >}}
+
+Adding images to the `.navbar-brand` will likely always require custom styles or utilities to properly size. Here are some examples to demonstrate.
+
+{{< example >}}
+<!-- Just an image -->
+<nav class="navbar navbar-light bg-light">
+  <a class="navbar-brand" href="#">
+    <img src="/docs/{{< param docs_version >}}/assets/brand/bootstrap-solid.svg" width="30" height="30" alt="">
+  </a>
+</nav>
+{{< /example >}}
+
+{{< example >}}
+<!-- Image and text -->
+<nav class="navbar navbar-light bg-light">
+  <a class="navbar-brand" href="#">
+    <img src="/docs/{{< param docs_version >}}/assets/brand/bootstrap-solid.svg" width="30" height="30" class="d-inline-block align-top" alt="">
+    Bootstrap
+  </a>
+</nav>
+{{< /example >}}
+
+### Nav
+
+Navbar navigation links build on our `.nav` options with their own modifier class and require the use of [toggler classes](#toggler) for proper responsive styling. **Navigation in navbars will also grow to occupy as much horizontal space as possible** to keep your navbar contents securely aligned.
+
+Active states—with `.active`—to indicate the current page can be applied directly to `.nav-link`s or their immediate parent `.nav-item`s.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <div class="collapse navbar-collapse" id="navbarNav">
+    <ul class="navbar-nav">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Features</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Pricing</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+  </div>
+</nav>
+{{< /example >}}
+
+And because we use classes for our navs, you can avoid the list-based approach entirely if you like.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
+    <div class="navbar-nav">
+      <a class="nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
+      <a class="nav-link" href="#">Features</a>
+      <a class="nav-link" href="#">Pricing</a>
+      <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+    </div>
+  </div>
+</nav>
+{{< /example >}}
+
+You can also use dropdowns in your navbar. Dropdown menus require a wrapping element for positioning, so be sure to use separate and nested elements for `.nav-item` and `.nav-link` as shown below.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <div class="collapse navbar-collapse" id="navbarNavDropdown">
+    <ul class="navbar-nav">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Features</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Pricing</a>
+      </li>
+      <li class="nav-item dropdown">
+        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
+          Dropdown link
+        </a>
+        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
+          <a class="dropdown-item" href="#">Action</a>
+          <a class="dropdown-item" href="#">Another action</a>
+          <a class="dropdown-item" href="#">Something else here</a>
+        </div>
+      </li>
+    </ul>
+  </div>
+</nav>
+{{< /example >}}
+
+### Forms
+
+Place various form controls and components within a navbar with `.form-inline`.
+
+{{< example >}}
+<nav class="navbar navbar-light bg-light">
+  <form class="form-inline">
+    <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
+    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
+  </form>
+</nav>
+{{< /example >}}
+
+Immediate child elements of `.navbar` use flex layout and will default to `justify-content: space-between`. Use additional [flex utilities]({{< docsref "/utilities/flex" >}}) as needed to adjust this behavior.
+
+{{< example >}}
+<nav class="navbar navbar-light bg-light">
+  <a class="navbar-brand">Navbar</a>
+  <form class="form-inline">
+    <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
+    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
+  </form>
+</nav>
+{{< /example >}}
+
+Input groups work, too:
+
+{{< example >}}
+<nav class="navbar navbar-light bg-light">
+  <form class="form-inline">
+    <div class="input-group">
+      <div class="input-group-prepend">
+        <span class="input-group-text" id="basic-addon1">@</span>
+      </div>
+      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
+    </div>
+  </form>
+</nav>
+{{< /example >}}
+
+Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.
+
+{{< example >}}
+<nav class="navbar navbar-light bg-light">
+  <form class="form-inline">
+    <button class="btn btn-outline-success" type="button">Main button</button>
+    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
+  </form>
+</nav>
+{{< /example >}}
+
+### Text
+
+Navbars may contain bits of text with the help of `.navbar-text`. This class adjusts vertical alignment and horizontal spacing for strings of text.
+
+{{< example >}}
+<nav class="navbar navbar-light bg-light">
+  <span class="navbar-text">
+    Navbar text with an inline element
+  </span>
+</nav>
+{{< /example >}}
+
+Mix and match with other components and utilities as needed.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar w/ text</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <div class="collapse navbar-collapse" id="navbarText">
+    <ul class="navbar-nav mr-auto">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Features</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Pricing</a>
+      </li>
+    </ul>
+    <span class="navbar-text">
+      Navbar text with an inline element
+    </span>
+  </div>
+</nav>
+{{< /example >}}
+
+## Color schemes
+
+Theming the navbar has never been easier thanks to the combination of theming classes and `background-color` utilities. Choose from `.navbar-light` for use with light background colors, or `.navbar-dark` for dark background colors. Then, customize with `.bg-*` utilities.
+
+<div class="bd-example">
+  <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
+    <a class="navbar-brand" href="#">Navbar</a>
+    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation">
+      <span class="navbar-toggler-icon"></span>
+    </button>

+<nav class="navbar navbar-dark bg-dark">

+
+<nav class="navbar navbar-dark bg-primary">
+  <!-- Navbar content -->
+</nav>
+
+<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
+  <!-- Navbar content -->
+</nav>
+```
+
+## Containers
+
+Although it's not required, you can wrap a navbar in a `.container` to center it on a page. Or you can add a container inside the `.navbar` to only center the contents of a [fixed or static top navbar](#placement).
+
+{{< example >}}
+<div class="container">
+  <nav class="navbar navbar-expand-lg navbar-light bg-light">
+    <a class="navbar-brand" href="#">Navbar</a>
+  </nav>
+</div>
+{{< /example >}}
+
+When the container is within your navbar, its horizontal padding is removed at breakpoints lower than your specified `.navbar-expand{-sm|-md|-lg|-xl}` class. This ensures we're not doubling up on padding unnecessarily on lower viewports when your navbar is collapsed.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <div class="container">
+    <a class="navbar-brand" href="#">Navbar</a>
+  </div>
+</nav>
+{{< /example >}}
+
+## Placement
+
+Use our [position utilities]({{< docsref "/utilities/position" >}}) to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use `position: fixed`, meaning they're pulled from the normal flow of the DOM and may require custom CSS (e.g., `padding-top` on the `<body>`) to prevent overlap with other elements.
+
+Also note that **`.sticky-top` uses `position: sticky`, which [isn't fully supported in every browser](https://caniuse.com/css-sticky)**.
+
+{{< example >}}
+<nav class="navbar navbar-light bg-light">
+  <a class="navbar-brand" href="#">Default</a>
+</nav>
+{{< /example >}}
+
+{{< example >}}
+<nav class="navbar fixed-top navbar-light bg-light">
+  <a class="navbar-brand" href="#">Fixed top</a>
+</nav>
+{{< /example >}}
+
+{{< example >}}
+<nav class="navbar fixed-bottom navbar-light bg-light">
+  <a class="navbar-brand" href="#">Fixed bottom</a>
+</nav>
+{{< /example >}}
+
+{{< example >}}
+<nav class="navbar sticky-top navbar-light bg-light">
+  <a class="navbar-brand" href="#">Sticky top</a>
+</nav>
+{{< /example >}}
+
+## Scrolling
+
+Add `.navbar-nav-scroll` to a `.navbar-collapse` (or other navbar sub-component) to enable vertical scrolling within the toggleable contents of a collapsed navbar. By default, scrolling kicks in at `75vh` (or 75% of the viewport height), but you can override that with inline or custom styles. At larger viewports when the navbar is expanded, content will appear as it does in a default navbar.
+
+Please note that this behavior comes with a potential drawback of `overflow`—when setting `overflow-y: auto` (required to scroll the content here), `overflow-x` is the equivalent of `auto`, which will crop some horizontal content.
+
+Here's an example navbar using `.navbar-nav-scroll` with `style="max-height: 100px;"`, with some extra margin utilities for optimum spacing.
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar scroll</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarScroll" aria-controls="navbarScroll" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <div class="collapse navbar-collapse" id="navbarScroll">
+    <ul class="navbar-nav mr-auto my-2 my-lg-0 navbar-nav-scroll" style="max-height: 100px;">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item dropdown">
+        <a class="nav-link dropdown-toggle" href="#" id="navbarScrollingDropdown" role="button" data-toggle="dropdown" aria-expanded="false">
+          Link
+        </a>
+        <ul class="dropdown-menu" aria-labelledby="navbarScrollingDropdown">
+          <li><a class="dropdown-item" href="#">Action</a></li>
+          <li><a class="dropdown-item" href="#">Another action</a></li>
+          <li><hr class="dropdown-divider"></li>
+          <li><a class="dropdown-item" href="#">Something else here</a></li>
+        </ul>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Link</a>
+      </li>
+    </ul>
+    <form class="d-flex">
+      <input class="form-control mr-2" type="search" placeholder="Search" aria-label="Search">
+      <button class="btn btn-outline-success" type="submit">Search</button>
+    </form>
+  </div>
+</nav>
+{{< /example >}}
+
+## Responsive behaviors
+
+Navbars can use `.navbar-toggler`, `.navbar-collapse`, and `.navbar-expand{-sm|-md|-lg|-xl}` classes to determine when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.
+
+For navbars that never collapse, add the `.navbar-expand` class on the navbar. For navbars that always collapse, don't add any `.navbar-expand` class.
+
+### Toggler
+
+Navbar togglers are left-aligned by default, but should they follow a sibling element like a `.navbar-brand`, they'll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.
+
+With no `.navbar-brand` shown at the smallest breakpoint:
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
+    <a class="navbar-brand" href="#">Hidden brand</a>
+    <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+    <form class="form-inline my-2 my-lg-0">
+      <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
+      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
+    </form>
+  </div>
+</nav>
+{{< /example >}}
+
+With a brand name shown on the left and toggler on the right:
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <a class="navbar-brand" href="#">Navbar</a>
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+
+  <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
+    <ul class="navbar-nav mr-auto mt-2 mt-lg-0">

+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+    <form class="form-inline my-2 my-lg-0">

+      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
+    </form>
+  </div>
+</nav>
+{{< /example >}}
+
+With a toggler on the left and brand name on the right:
+
+{{< example >}}
+<nav class="navbar navbar-expand-lg navbar-light bg-light">
+  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo03" aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation">
+    <span class="navbar-toggler-icon"></span>
+  </button>
+  <a class="navbar-brand" href="#">Navbar</a>
+
+  <div class="collapse navbar-collapse" id="navbarTogglerDemo03">
+    <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
+      <li class="nav-item active">
+        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link" href="#">Link</a>
+      </li>
+      <li class="nav-item">
+        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+      </li>
+    </ul>
+    <form class="form-inline my-2 my-lg-0">
+      <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
+      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
+    </form>
+  </div>
+</nav>
+{{< /example >}}
+
+### External content
+
+Sometimes you want to use the collapse plugin to trigger a container element for content that structurally sits outside of the `.navbar` . Because our plugin works on the `id` and `data-target` matching, that's easily done!
+
+{{< example >}}
+<div class="fixed-top">
+  <div class="collapse" id="navbarToggleExternalContent">
+    <div class="bg-dark p-4">
+      <h5 class="text-white h4">Collapsed content</h5>
+      <span class="text-muted">Toggleable via the navbar brand.</span>
+    </div>
+  </div>
+  <nav class="navbar navbar-dark bg-dark">
+    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
+      <span class="navbar-toggler-icon"></span>
+    </button>
+  </nav>
+</div>
+{{< /example >}}
+
+When you do this, we recommend including additional JavaScript to move the focus programmatically to the container when it is opened. Otherwise, keyboard users and users of assistive technologies will likely have a hard time finding the newly revealed content - particularly if the container that was opened comes *before* the toggler in the document's structure. We also recommend making sure that the toggler has the `aria-controls` attribute, pointing to the `id` of the content container. In theory, this allows assistive technology users to jump directly from the toggler to the container it controls–but support for this is currently quite patchy.

+## Base nav
+
+Navigation available in Bootstrap share general markup and styles, from the base `.nav` class to the active and disabled states. Swap modifier classes to switch between each style.
+
+The base `.nav` component is built with flexbox and provide a strong foundation for building all types of navigation components. It includes some style overrides (for working with lists), some link padding for larger hit areas, and basic disabled styling.
+
+{{< callout info >}}
+The base `.nav` component does not include any `.active` state. The following examples include the class, mainly to demonstrate that this particular class does not trigger any special styling.
+{{< /callout >}}
+
+{{< example >}}
+<ul class="nav">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+Classes are used throughout, so your markup can be super flexible. Use `<ul>`s like above, `<ol>` if the order of your items is important, or roll your own with a `<nav>` element. Because the `.nav` uses `display: flex`, the nav links behave the same as nav items would, but without the extra markup.
+
+{{< example >}}
+<nav class="nav">
+  <a class="nav-link active" href="#">Active</a>
+  <a class="nav-link" href="#">Link</a>
+  <a class="nav-link" href="#">Link</a>
+  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+</nav>
+{{< /example >}}
+
+## Available styles
+
+Change the style of `.nav`s component with modifiers and utilities. Mix and match as needed, or build your own.
+
+### Horizontal alignment
+
+Change the horizontal alignment of your nav with [flexbox utilities]({{< docsref "/layout/grid#horizontal-alignment" >}}). By default, navs are left-aligned, but you can easily change them to center or right aligned.
+
+Centered with `.justify-content-center`:
+
+{{< example >}}
+<ul class="nav justify-content-center">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+Right-aligned with `.justify-content-end`:
+
+{{< example >}}
+<ul class="nav justify-content-end">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+### Vertical
+
+Stack your navigation by changing the flex item direction with the `.flex-column` utility. Need to stack them on some viewports but not others? Use the responsive versions (e.g., `.flex-sm-column`).
+
+{{< example >}}
+<ul class="nav flex-column">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+As always, vertical navigation is possible without `<ul>`s, too.
+
+{{< example >}}
+<nav class="nav flex-column">
+  <a class="nav-link active" href="#">Active</a>
+  <a class="nav-link" href="#">Link</a>
+  <a class="nav-link" href="#">Link</a>
+  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+</nav>
+{{< /example >}}
+
+### Tabs
+
+Takes the basic nav from above and adds the `.nav-tabs` class to generate a tabbed interface. Use them to create tabbable regions with our [tab JavaScript plugin](#javascript-behavior).
+
+{{< example >}}
+<ul class="nav nav-tabs">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+### Pills
+
+Take that same HTML, but use `.nav-pills` instead:
+
+{{< example >}}
+<ul class="nav nav-pills">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+### Fill and justify
+
+Force your `.nav`'s contents to extend the full available width one of two modifier classes. To proportionately fill all available space with your `.nav-item`s, use `.nav-fill`. Notice that all horizontal space is occupied, but not every nav item has the same width.
+
+{{< example >}}
+<ul class="nav nav-pills nav-fill">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Much longer nav link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+When using a `<nav>`-based navigation, you can safely omit `.nav-item` as only `.nav-link` is required for styling `<a>` elements.
+
+{{< example >}}
+<nav class="nav nav-pills nav-fill">
+  <a class="nav-link active" href="#">Active</a>
+  <a class="nav-link" href="#">Much longer nav link</a>
+  <a class="nav-link" href="#">Link</a>
+  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+</nav>
+{{< /example >}}
+
+For equal-width elements, use `.nav-justified`. All horizontal space will be occupied by nav links, but unlike the `.nav-fill` above, every nav item will be the same width.
+
+{{< example >}}
+<ul class="nav nav-pills nav-justified">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Much longer nav link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+Similar to the `.nav-fill` example using a `<nav>`-based navigation.
+
+{{< example >}}
+<nav class="nav nav-pills nav-justified">
+  <a class="nav-link active" href="#">Active</a>
+  <a class="nav-link" href="#">Much longer nav link</a>
+  <a class="nav-link" href="#">Link</a>
+  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+</nav>
+
+{{< /example >}}
+## Working with flex utilities
+
+If you need responsive nav variations, consider using a series of [flexbox utilities]({{< docsref "/utilities/flex" >}}). While more verbose, these utilities offer greater customization across responsive breakpoints. In the example below, our nav will be stacked on the lowest breakpoint, then adapt to a horizontal layout that fills the available width starting from the small breakpoint.
+
+{{< example >}}
+<nav class="nav nav-pills flex-column flex-sm-row">
+  <a class="flex-sm-fill text-sm-center nav-link active" href="#">Active</a>
+  <a class="flex-sm-fill text-sm-center nav-link" href="#">Longer nav link</a>
+  <a class="flex-sm-fill text-sm-center nav-link" href="#">Link</a>
+  <a class="flex-sm-fill text-sm-center nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+</nav>
+{{< /example >}}
+
+## Regarding accessibility
+
+If you're using navs to provide a navigation bar, be sure to add a `role="navigation"` to the most logical parent container of the `<ul>`, or wrap a `<nav>` element around the whole navigation. Do not add the role to the `<ul>` itself, as this would prevent it from being announced as an actual list by assistive technologies.
+
+Note that navigation bars, even if visually styled as tabs with the `.nav-tabs` class, should **not** be given `role="tablist"`, `role="tab"` or `role="tabpanel"` attributes. These are only appropriate for dynamic tabbed interfaces, as described in the [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr> Authoring Practices](https://www.w3.org/TR/wai-aria-practices/#tabpanel). See [JavaScript behavior](#javascript-behavior) for dynamic tabbed interfaces in this section for an example.
+
+## Using dropdowns
+
+Add dropdown menus with a little extra HTML and the [dropdowns JavaScript plugin]({{< docsref "/components/dropdowns#usage" >}}).
+
+### Tabs with dropdowns
+
+{{< example >}}
+<ul class="nav nav-tabs">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item dropdown">
+    <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
+    <div class="dropdown-menu">
+      <a class="dropdown-item" href="#">Action</a>
+      <a class="dropdown-item" href="#">Another action</a>
+      <a class="dropdown-item" href="#">Something else here</a>
+      <div class="dropdown-divider"></div>
+      <a class="dropdown-item" href="#">Separated link</a>
+    </div>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+### Pills with dropdowns
+
+{{< example >}}
+<ul class="nav nav-pills">
+  <li class="nav-item">
+    <a class="nav-link active" href="#">Active</a>
+  </li>
+  <li class="nav-item dropdown">
+    <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
+    <div class="dropdown-menu">
+      <a class="dropdown-item" href="#">Action</a>
+      <a class="dropdown-item" href="#">Another action</a>
+      <a class="dropdown-item" href="#">Something else here</a>
+      <div class="dropdown-divider"></div>
+      <a class="dropdown-item" href="#">Separated link</a>
+    </div>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link" href="#">Link</a>
+  </li>
+  <li class="nav-item">
+    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
+  </li>
+</ul>
+{{< /example >}}
+
+## JavaScript behavior
+
+Use the tab JavaScript plugin—include it individually or through the compiled `bootstrap.js` file—to extend our navigational tabs and pills to create tabbable panes of local content.
+
+If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+
+Dynamic tabbed interfaces, as described in the [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr> Authoring Practices](https://www.w3.org/TR/wai-aria-practices/#tabpanel), require `role="tablist"`, `role="tab"`, `role="tabpanel"`, and additional `aria-` attributes in order to convey their structure, functionality and current state to users of assistive technologies (such as screen readers).
+
+Note that dynamic tabbed interfaces should <em>not</em> contain dropdown menus, as this causes both usability and accessibility issues. From a usability perspective, the fact that the currently displayed tab's trigger element is not immediately visible (as it's inside the closed dropdown menu) can cause confusion. From an accessibility point of view, there is currently no sensible way to map this sort of construct to a standard WAI ARIA pattern, meaning that it cannot be easily made understandable to users of assistive technologies.

+
+To help fit your needs, this works with `<ul>`-based markup, as shown above, or with any arbitrary "roll your own" markup. Note that if you're using `<nav>`, you shouldn't add `role="tablist"` directly to it, as this would override the element's native role as a navigation landmark. Instead, switch to an alternative element (in the example below, a simple `<div>`) and wrap the `<nav>` around it.

+
+### Using data attributes
+
+You can activate a tab or pill navigation without writing any JavaScript by simply specifying `data-toggle="tab"` or `data-toggle="pill"` on an element. Use these data attributes on `.nav-tabs` or `.nav-pills`.
+
+```html
+<!-- Nav tabs -->
+<ul class="nav nav-tabs" id="myTab" role="tablist">
+  <li class="nav-item" role="presentation">
+    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
+  </li>
+  <li class="nav-item" role="presentation">
+    <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
+  </li>
+  <li class="nav-item" role="presentation">
+    <a class="nav-link" id="messages-tab" data-toggle="tab" href="#messages" role="tab" aria-controls="messages" aria-selected="false">Messages</a>
+  </li>
+  <li class="nav-item" role="presentation">
+    <a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
+  </li>
+</ul>
+
+<!-- Tab panes -->
+<div class="tab-content">
+  <div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
+  <div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
+  <div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
+  <div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
+</div>
+```
+
+### Via JavaScript
+
+Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
+
+```js
+$('#myTab a').on('click', function (event) {
+  event.preventDefault()
+  $(this).tab('show')
+})
+```
+
+You can activate individual tabs in several ways:
+
+```js
+$('#myTab a[href="#profile"]').tab('show') // Select tab by name
+$('#myTab li:first-child a').tab('show') // Select first tab
+$('#myTab li:last-child a').tab('show') // Select last tab
+$('#myTab li:nth-child(3) a').tab('show') // Select third tab
+```
+
+### Fade effect
+
+To make tabs fade in, add `.fade` to each `.tab-pane`. The first tab pane must also have `.show` to make the initial content visible.
+
+```html
+<div class="tab-content">
+  <div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
+  <div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
+  <div class="tab-pane fade" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
+  <div class="tab-pane fade" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
+</div>
+```
+
+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### $().tab
+
+Activates a tab element and content container. Tab should have either a `data-target` or an `href` targeting a container node in the DOM.
+
+```html
+<ul class="nav nav-tabs" id="myTab" role="tablist">
+  <li class="nav-item" role="presentation">
+    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
+  </li>
+  <li class="nav-item" role="presentation">

+
+#### .tab('show')
+
+Selects the given tab and shows its associated pane. Any other tab that was previously selected becomes unselected and its associated pane is hidden. **Returns to the caller before the tab pane has actually been shown** (i.e. before the `shown.bs.tab` event occurs).
+
+```js

+#### .tab('dispose')
+
+Destroys an element's tab.
+
+### Events
+
+When showing a new tab, the events fire in the following order:
+
+1. `hide.bs.tab` (on the current active tab)
+2. `show.bs.tab` (on the to-be-shown tab)
+3. `hidden.bs.tab` (on the previous active tab, the same one as for the `hide.bs.tab` event)
+4. `shown.bs.tab` (on the newly-active just-shown tab, the same one as for the `show.bs.tab` event)
+
+If no tab was already active, then the `hide.bs.tab` and `hidden.bs.tab` events will not be fired.

+title: Pagination
+description: Documentation and examples for showing pagination to indicate a series of related content exists across multiple pages.
+group: components
+toc: true
+---
+
+## Overview
+
+We use a large block of connected links for our pagination, making links hard to miss and easily scalable—all while providing large hit areas. Pagination is built with list HTML elements so screen readers can announce the number of available links. Use a wrapping `<nav>` element to identify it as a navigation section to screen readers and other assistive technologies.
+
+In addition, as pages likely have more than one such navigation section, it's advisable to provide a descriptive `aria-label` for the `<nav>` to reflect its purpose. For example, if the pagination component is used to navigate between a set of search results, an appropriate label could be `aria-label="Search results pages"`.
+
+{{< example >}}
+<nav aria-label="Page navigation example">
+  <ul class="pagination">
+    <li class="page-item"><a class="page-link" href="#">Previous</a></li>
+    <li class="page-item"><a class="page-link" href="#">1</a></li>
+    <li class="page-item"><a class="page-link" href="#">2</a></li>
+    <li class="page-item"><a class="page-link" href="#">3</a></li>
+    <li class="page-item"><a class="page-link" href="#">Next</a></li>
+  </ul>
+</nav>
+{{< /example >}}
+
+## Working with icons
+
+Looking to use an icon or symbol in place of text for some pagination links? Be sure to provide proper screen reader support with `aria` attributes.
+
+{{< example >}}
+<nav aria-label="Page navigation example">
+  <ul class="pagination">
+    <li class="page-item">
+      <a class="page-link" href="#" aria-label="Previous">
+        <span aria-hidden="true">&laquo;</span>
+      </a>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">1</a></li>
+    <li class="page-item"><a class="page-link" href="#">2</a></li>
+    <li class="page-item"><a class="page-link" href="#">3</a></li>
+    <li class="page-item">
+      <a class="page-link" href="#" aria-label="Next">
+        <span aria-hidden="true">&raquo;</span>
+      </a>
+    </li>
+  </ul>
+</nav>
+{{< /example >}}
+
+## Disabled and active states
+
+Pagination links are customizable for different circumstances. Use `.disabled` for links that appear un-clickable and `.active` to indicate the current page.
+
+While the `.disabled` class uses `pointer-events: none` to _try_ to disable the link functionality of `<a>`s, that CSS property is not yet standardized and doesn't account for keyboard navigation. As such, you should always add `tabindex="-1"` on disabled links and use custom JavaScript to fully disable their functionality.
+
+{{< example >}}
+<nav aria-label="...">
+  <ul class="pagination">
+    <li class="page-item disabled">
+      <a class="page-link" href="#" tabindex="-1" aria-disabled="true">Previous</a>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">1</a></li>
+    <li class="page-item active" aria-current="page">
+      <a class="page-link" href="#">2</a>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">3</a></li>
+    <li class="page-item">
+      <a class="page-link" href="#">Next</a>
+    </li>
+  </ul>
+</nav>
+{{< /example >}}
+
+You can optionally swap out active or disabled anchors for `<span>`, or omit the anchor in the case of the prev/next arrows, to remove click functionality and prevent keyboard focus while retaining intended styles.
+
+{{< example >}}
+<nav aria-label="...">
+  <ul class="pagination">
+    <li class="page-item disabled">
+      <span class="page-link">Previous</span>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">1</a></li>
+    <li class="page-item active" aria-current="page">
+      <span class="page-link">2</span>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">3</a></li>
+    <li class="page-item">
+      <a class="page-link" href="#">Next</a>
+    </li>
+  </ul>
+</nav>
+{{< /example >}}
+
+## Sizing
+
+Fancy larger or smaller pagination? Add `.pagination-lg` or `.pagination-sm` for additional sizes.
+
+{{< example >}}
+<nav aria-label="...">
+  <ul class="pagination pagination-lg">
+    <li class="page-item active" aria-current="page">
+      <span class="page-link">1</span>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">2</a></li>
+    <li class="page-item"><a class="page-link" href="#">3</a></li>
+  </ul>
+</nav>
+{{< /example >}}
+
+{{< example >}}
+<nav aria-label="...">
+  <ul class="pagination pagination-sm">
+    <li class="page-item active" aria-current="page">
+      <span class="page-link">1</span>
+    </li>
+    <li class="page-item"><a class="page-link" href="#">2</a></li>
+    <li class="page-item"><a class="page-link" href="#">3</a></li>
+  </ul>
+</nav>
+{{< /example >}}
+
+## Alignment
+
+Change the alignment of pagination components with [flexbox utilities]({{< docsref "/utilities/flex" >}}).
+
+{{< example >}}
+<nav aria-label="Page navigation example">
+  <ul class="pagination justify-content-center">
+    <li class="page-item disabled">
+      <a class="page-link" href="#" tabindex="-1" aria-disabled="true">Previous</a>

+    </li>
+  </ul>
+</nav>
+{{< /example >}}

+title: Popovers
+description: Documentation and examples for adding Bootstrap popovers, like those found in iOS, to any element on your site.
+group: components
+toc: true
+---
+
+## Overview
+
+Things to know when using the popover plugin:
+
+- Popovers rely on the 3rd party library [Popper](https://popper.js.org/) for positioning. You must include [popper.min.js]({{< param "cdn.popper" >}}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper in order for popovers to work!
+- Popovers require the [tooltip plugin]({{< docsref "/components/tooltips" >}}) as a dependency.
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+- Popovers are opt-in for performance reasons, so **you must initialize them yourself**.
+- Zero-length `title` and `content` values will never show a popover.
+- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
+- Triggering popovers on hidden elements will not work.
+- Popovers for `.disabled` or `disabled` elements must be triggered on a wrapper element.
+- When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors' overall width. Use `.text-nowrap` on your `<a>`s to avoid this behavior.
+- Popovers must be hidden before their corresponding elements have been removed from the DOM.
+- Popovers can be triggered thanks to an element inside a shadow DOM.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+Keep reading to see how popovers work with some examples.
+
+## Example: Enable popovers everywhere
+
+One way to initialize all popovers on a page would be to select them by their `data-toggle` attribute:
+
+```js
+$(function () {
+  $('[data-toggle="popover"]').popover()
+})
+```
+
+## Example: Using the `container` option
+
+When you have some styles on a parent element that interfere with a popover, you'll want to specify a custom `container` so that the popover's HTML appears within that element instead.
+
+```js
+$(function () {
+  $('.example-popover').popover({
+    container: 'body'
+  })
+})
+```
+
+## Example
+
+{{< example >}}
+<button type="button" class="btn btn-lg btn-danger" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>
+{{< /example >}}
+
+### Four directions
+
+Four options are available: top, right, bottom, and left aligned.
+
+{{< example >}}
+<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Top popover">
+  Popover on top
+</button>
+<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Right popover">
+  Popover on right
+</button>
+<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Bottom popover">
+  Popover on bottom
+</button>
+<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Left popover">
+  Popover on left
+</button>
+{{< /example >}}
+
+### Dismiss on next click
+
+Use the `focus` trigger to dismiss popovers on the user's next click of a different element than the toggle element.
+
+{{< callout danger >}}
+#### Specific markup required for dismiss-on-next-click
+
+For proper cross-browser and cross-platform behavior, you must use the `<a>` tag, _not_ the `<button>` tag, and you also must include a [`tabindex`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex) attribute.
+{{< /callout >}}
+
+{{< example >}}
+<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here's some amazing content. It's very engaging. Right?">Dismissible popover</a>
+{{< /example >}}
+
+```js
+$('.popover-dismiss').popover({
+  trigger: 'focus'
+})
+```
+
+### Disabled elements
+
+Elements with the `disabled` attribute aren't interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you'll want to trigger the popover from a wrapper `<div>` or `<span>` and override the `pointer-events` on the disabled element.
+
+For disabled popover triggers, you may also prefer `data-trigger="hover"` so that the popover appears as immediate visual feedback to your users as they may not expect to _click_ on a disabled element.
+
+{{< example >}}
+<span class="d-inline-block" data-toggle="popover" data-content="Disabled popover">
+  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
+</span>
+{{< /example >}}
+
+## Usage
+
+Enable popovers via JavaScript:
+
+```js
+$('#example').popover(options)
+```
+
+{{< callout warning >}}
+##### GPU acceleration
+
+Popovers sometimes appear blurry on Windows 10 devices due to GPU acceleration and a modified system DPI. The workaround for this in v4 is to disable GPU acceleration as needed on your popovers.
+
+Suggested fix:
+
+```js
+Popper.Defaults.modifiers.computeStyle.gpuAcceleration = !(window.devicePixelRatio < 1.5 && /Win/.test(navigator.platform))
+```
+{{< /callout >}}
+
+{{< callout warning >}}
+### Making popovers work for keyboard and assistive technology users
+
+To allow keyboard users to activate your popovers, you should only add them to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as `<span>`s) can be made focusable by adding the `tabindex="0"` attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users, and most assistive technologies currently do not announce the popover's content in this situation. Additionally, do not rely solely on `hover` as the trigger for your popovers, as this will make them impossible to trigger for keyboard users.
+
+While you can insert rich, structured HTML in popovers with the `html` option, we strongly recommend that you avoid adding an excessive amount of content. The way popovers currently work is that, once displayed, their content is tied to the trigger element with the `aria-describedby` attribute. As a result, the entirety of the popover's content will be announced to assistive technology users as one long, uninterrupted stream.
+
+Additionally, while it is possible to also include interactive controls (such as form elements or links) in your popover (by adding these elements to the `whiteList` or allowed attributes and tags), be aware that currently the popover does not manage keyboard focus order. When a keyboard user opens a popover, focus remains on the triggering element, and as the popover usually does not immediately follow the trigger in the document's structure, there is no guarantee that moving forward/pressing <kbd>TAB</kbd> will move a keyboard user into the popover itself. In short, simply adding interactive controls to a popover is likely to make these controls unreachable/unusable for keyboard users and users of assistive technologies, or at the very least make for an illogical overall focus order. In these cases, consider using a modal dialog instead.
+{{< /callout >}}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.
+
+{{< callout warning >}}
+Note that for security reasons the `sanitize`, `sanitizeFn` and `whiteList` options cannot be supplied using data attributes.

+#### Data attributes for individual popovers
+
+Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.
+{{< /callout >}}
+
+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### `$().popover(options)`
+
+Initializes popovers for an element collection.
+
+#### `.popover('show')`
+
+Reveals an element's popover. **Returns to the caller before the popover has actually been shown** (i.e. before the `shown.bs.popover` event occurs). This is considered a "manual" triggering of the popover. Popovers whose title and content are both zero-length are never displayed.
+
+```js
+$('#element').popover('show')
+```
+
+#### `.popover('hide')`
+
+Hides an element's popover. **Returns to the caller before the popover has actually been hidden** (i.e. before the `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.
+
+```js
+$('#element').popover('hide')
+```
+
+#### `.popover('toggle')`
+
+Toggles an element's popover. **Returns to the caller before the popover has actually been shown or hidden** (i.e. before the `shown.bs.popover` or `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.
+
+```js
+$('#element').popover('toggle')
+```
+
+#### `.popover('dispose')`
+
+Hides and destroys an element's popover. Popovers that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.
+
+```js
+$('#element').popover('dispose')
+```
+
+#### `.popover('enable')`
+
+Gives an element's popover the ability to be shown. **Popovers are enabled by default.**
+
+```js
+$('#element').popover('enable')
+```
+
+#### `.popover('disable')`
+
+Removes the ability for an element's popover to be shown. The popover will only be able to be shown if it is re-enabled.
+
+```js
+$('#element').popover('disable')
+```
+
+#### `.popover('toggleEnabled')`
+
+Toggles the ability for an element's popover to be shown or hidden.
+
+```js
+$('#element').popover('toggleEnabled')
+```
+
+#### `.popover('update')`
+
+Updates the position of an element's popover.
+
+```js
+$('#element').popover('update')
+```
+

+title: Progress
+description: Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels.
+group: components
+toc: true
+---
+
+## How it works
+
+Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don't use [the HTML5 `<progress>` element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress), ensuring you can stack progress bars, animate them, and place text labels over them.
+
+- We use the `.progress` as a wrapper to indicate the max value of the progress bar.
+- We use the inner `.progress-bar` to indicate the progress so far.
+- The `.progress-bar` requires an inline style, utility class, or custom CSS to set their width.
+- The `.progress-bar` also requires some `role` and `aria` attributes to make it accessible.
+
+Put that all together, and you have the following examples.
+
+{{< example >}}
+<div class="progress">
+  <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+{{< /example >}}
+
+Bootstrap provides a handful of [utilities for setting width]({{< docsref "/utilities/sizing" >}}). Depending on your needs, these may help with quickly configuring progress.
+
+{{< example >}}
+<div class="progress">
+  <div class="progress-bar w-75" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+{{< /example >}}
+
+## Labels
+
+Add labels to your progress bars by placing text within the `.progress-bar`.
+
+{{< example >}}
+<div class="progress">
+  <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
+</div>
+{{< /example >}}
+
+## Height
+
+We only set a `height` value on the `.progress`, so if you change that value the inner `.progress-bar` will automatically resize accordingly.
+
+{{< example >}}
+<div class="progress" style="height: 1px;">
+  <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress" style="height: 20px;">
+  <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+{{< /example >}}
+
+## Backgrounds
+
+Use background utility classes to change the appearance of individual progress bars.
+
+{{< example >}}
+<div class="progress">
+  <div class="progress-bar bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+{{< /example >}}
+
+## Multiple bars
+
+Include multiple progress bars in a progress component if you need.
+
+{{< example >}}
+<div class="progress">
+  <div class="progress-bar" role="progressbar" style="width: 15%" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100"></div>
+  <div class="progress-bar bg-success" role="progressbar" style="width: 30%" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100"></div>
+  <div class="progress-bar bg-info" role="progressbar" style="width: 20%" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+{{< /example >}}
+
+## Striped
+
+Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar's background color.
+
+{{< example >}}
+<div class="progress">
+  <div class="progress-bar progress-bar-striped" role="progressbar" style="width: 10%" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar progress-bar-striped bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar progress-bar-striped bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar progress-bar-striped bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+<div class="progress">
+  <div class="progress-bar progress-bar-striped bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
+</div>
+{{< /example >}}
+
+## Animated stripes
+
+The striped gradient can also be animated. Add `.progress-bar-animated` to `.progress-bar` to animate the stripes right to left via CSS3 animations.
+
+<div class="bd-example">
+  <div class="progress">
+    <div class="progress-bar progress-bar-striped" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
+  </div>
+  <button type="button" class="btn btn-secondary bd-toggle-animated-progress" data-toggle="button" aria-pressed="false">
+    Toggle animation
+  </button>
+</div>
+
+```html
+<div class="progress">
+  <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
+</div>

+title: Scrollspy
+description: Automatically update Bootstrap navigation or list group components based on scroll position to indicate which link is currently active in the viewport.
+group: components
+toc: true
+---
+
+## How it works
+
+Scrollspy has a few requirements to function properly:
+
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+- It must be used on a Bootstrap [nav component]({{< docsref "/components/navs" >}}) or [list group]({{< docsref "/components/list-group" >}}).
+- Scrollspy requires `position: relative;` on the element you're spying on, usually the `<body>`.
+- When spying on elements other than the `<body>`, be sure to have a `height` set and `overflow-y: scroll;` applied.
+- Anchors (`<a>`) are required and must point to an element with that `id`.
+
+When successfully implemented, your nav or list group will update accordingly, moving the `.active` class from one item to the next based on their associated targets.
+
+## Example in navbar
+
+Scroll the area below the navbar and watch the active class change. The dropdown items will be highlighted as well.
+
+<div class="bd-example">
+  <nav id="navbar-example2" class="navbar navbar-light bg-light">
+    <a class="navbar-brand" href="#">Navbar</a>
+    <ul class="nav nav-pills">
+      <li class="nav-item">
+        <a class="nav-link" href="#fat">@fat</a>

+      <li class="nav-item">
+        <a class="nav-link" href="#mdo">@mdo</a>
+      </li>
+      <li class="nav-item dropdown">
+        <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
+        <div class="dropdown-menu">
+          <a class="dropdown-item" href="#one">one</a>
+          <a class="dropdown-item" href="#two">two</a>

+          <a class="dropdown-item" href="#three">three</a>
+        </div>
+      </li>
+    </ul>
+  </nav>
+  <div data-spy="scroll" data-target="#navbar-example2" data-offset="0" class="scrollspy-example">

Oh, no. In another life I would make you stay. ‘Cause I, I’m capable of anything. Suiting up for my crowning battle. Used to steal your parents' liquor and climb to the roof. Tone, tan fit and ready, turn it up cause its gettin' heavy. Her love is like a drug. I guess that I forgot I had a choice.</p>
+    <h4 id="two">two</h4>
+    <p>Placeholder content for the scrollspy example. It's time to bring out the big balloons. I'm walking, I'm walking on air (tonight). Yeah, we maxed our credit cards and got kicked out of the bar. Yo, shout out to all you kids, buying bottle service, with your rent money. I'm ma get your heart racing in my skin-tight jeans.

+## Example with nested nav
+
+Scrollspy also works with nested `.nav`s. If a nested `.nav` is `.active`, its parents will also be `.active`. Scroll the area next to the navbar and watch the active class change.

+        <h4 id="list-item-3">Item 3</h4>
+        <p>Placeholder content for the scrollspy list-group example. This one relates to item 3. We go higher and higher. Never one without the other, we made a pact. I'm walking on air. Someone said you had your tattoo removed. Now I’m floating like a butterfly. Tone, tan fit and ready, turn it up cause its gettin' heavy. Cause once you’re mine, once you’re mine. You just gotta ignite the light and let it shine! So we hit the boulevard. Do you ever feel, feel so paper thin. I see it all, I see it now.</p>

+  <p>...</p>
+</div>
+```
+
+## Usage
+
+### Via data attributes
+
+To easily add scrollspy behavior to your topbar navigation, add `data-spy="scroll"` to the element you want to spy on (most typically this would be the `<body>`). Then add the `data-target` attribute with the ID or class of the parent element of any Bootstrap `.nav` component.
+
+```css
+body {
+  position: relative;
+}
+```
+
+```html
+<body data-spy="scroll" data-target="#navbar-example">
+  ...
+  <div id="navbar-example">
+    <ul class="nav nav-tabs" role="tablist">
+      ...
+    </ul>
+  </div>
+  ...
+</body>
+```
+
+### Via JavaScript
+
+After adding `position: relative;` in your CSS, call the scrollspy via JavaScript:
+
+```js
+$('body').scrollspy({ target: '#navbar-example' })
+```
+
+{{< callout danger >}}
+#### Resolvable ID targets required
+
+Navbar links must have resolvable id targets. For example, a `<a href="#home">home</a>` must correspond to something in the DOM like `<div id="home"></div>`.
+{{< /callout >}}
+
+{{< callout info >}}
+#### Non-`:visible` target elements ignored
+
+Target elements that are not [`:visible` according to jQuery](https://api.jquery.com/visible-selector/) will be ignored and their corresponding nav items will never be highlighted.
+{{< /callout >}}
+
+### Methods
+
+#### `.scrollspy('refresh')`
+
+When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:
+
+```js
+$('[data-spy="scroll"]').each(function () {
+  var $spy = $(this).scrollspy('refresh')
+})
+```
+
+#### `.scrollspy('dispose')`
+
+Destroys an element's scrollspy.
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-offset=""`.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 100px;">Type</th>
+      <th style="width: 50px;">Default</th>
+      <th>Description</th>
+    </tr>

+      <td>method</td>
+      <td>string</td>
+      <td>auto</td>
+      <td>Finds which section the spied element is in. <code>auto</code> will choose the best method to get scroll coordinates. <code>offset</code> will use jQuery offset method to get scroll coordinates. <code>position</code> will use jQuery position method to get scroll coordinates.</td>
+    </tr>
+    <tr>
+      <td>target</td>
+      <td>string | jQuery object | DOM element</td>
+      <td></td>

+title: Spinners
+description: Indicate the loading state of a component or page with Bootstrap spinners, built entirely with HTML, CSS, and no JavaScript.
+group: components
+toc: true
+---
+
+## About
+
+Bootstrap "spinners" can be used to show the loading state in your projects. They're built only with HTML and CSS, meaning you don't need any JavaScript to create them. You will, however, need some custom JavaScript to toggle their visibility. Their appearance, alignment, and sizing can be easily customized with our amazing utility classes.
+
+For accessibility purposes, each loader here includes `role="status"` and a nested `<span class="sr-only">Loading...</span>`.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+## Border spinner
+
+Use the border spinners for a lightweight loading indicator.
+
+{{< example >}}
+<div class="spinner-border" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{< /example >}}
+
+### Colors
+
+The border spinner uses `currentColor` for its `border-color`, meaning you can customize the color with [text color utilities][color]. You can use any of our text color utilities on the standard spinner.
+
+{{< example >}}
+{{< spinner.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="spinner-border text-{{ .name }}" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{- end -}}
+{{< /spinner.inline >}}
+{{< /example >}}
+
+{{< callout info >}}
+**Why not use `border-color` utilities?** Each border spinner specifies a `transparent` border for at least one side, so `.border-{color}` utilities would override that.
+{{< /callout >}}
+
+## Growing spinner
+
+If you don't fancy a border spinner, switch to the grow spinner. While it doesn't technically spin, it does repeatedly grow!
+
+{{< example >}}
+<div class="spinner-grow" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{< /example >}}
+
+Once again, this spinner is built with `currentColor`, so you can easily change its appearance with [text color utilities][color]. Here it is in blue, along with the supported variants.
+
+{{< example >}}
+{{< spinner.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="spinner-grow text-{{ .name }}" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{- end -}}
+{{< /spinner.inline >}}
+{{< /example >}}
+
+## Alignment
+
+Spinners in Bootstrap are built with `rem`s, `currentColor`, and `display: inline-flex`. This means they can easily be resized, recolored, and quickly aligned.
+
+### Margin
+
+Use [margin utilities][margin] like `.m-5` for easy spacing.
+
+{{< example >}}
+<div class="spinner-border m-5" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{< /example >}}
+
+### Placement
+
+Use [flexbox utilities][flex], [float utilities][float], or [text alignment][text] utilities to place spinners exactly where you need them in any situation.
+
+#### Flex
+
+{{< example >}}
+<div class="d-flex justify-content-center">
+  <div class="spinner-border" role="status">
+    <span class="sr-only">Loading...</span>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="d-flex align-items-center">
+  <strong>Loading...</strong>
+  <div class="spinner-border ml-auto" role="status" aria-hidden="true"></div>
+</div>
+{{< /example >}}
+
+#### Floats
+
+{{< example >}}
+<div class="clearfix">
+  <div class="spinner-border float-right" role="status">
+    <span class="sr-only">Loading...</span>
+  </div>
+</div>
+{{< /example >}}
+
+#### Text align
+
+{{< example >}}
+<div class="text-center">
+  <div class="spinner-border" role="status">
+    <span class="sr-only">Loading...</span>
+  </div>
+</div>
+{{< /example >}}
+
+## Size
+
+Add `.spinner-border-sm` and `.spinner-grow-sm` to make a smaller spinner that can quickly be used within other components.
+
+{{< example >}}
+<div class="spinner-border spinner-border-sm" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+<div class="spinner-grow spinner-grow-sm" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{< /example >}}
+
+Or, use custom CSS or inline styles to change the dimensions as needed.
+
+{{< example >}}
+<div class="spinner-border" style="width: 3rem; height: 3rem;" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+<div class="spinner-grow" style="width: 3rem; height: 3rem;" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{{< /example >}}
+
+## Buttons
+
+Use spinners within buttons to indicate an action is currently processing or taking place. You may also swap the text out of the spinner element and utilize button text as needed.
+
+{{< example >}}
+<button class="btn btn-primary" type="button" disabled>
+  <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
+  <span class="sr-only">Loading...</span>
+</button>
+<button class="btn btn-primary" type="button" disabled>
+  <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
+  Loading...
+</button>
+{{< /example >}}
+
+{{< example >}}
+<button class="btn btn-primary" type="button" disabled>
+  <span class="spinner-grow spinner-grow-sm" role="status" aria-hidden="true"></span>
+  <span class="sr-only">Loading...</span>
+</button>
+<button class="btn btn-primary" type="button" disabled>
+  <span class="spinner-grow spinner-grow-sm" role="status" aria-hidden="true"></span>
+  Loading...
+</button>
+{{< /example >}}

+title: Toasts
+description: Push notifications to your visitors with a toast, a lightweight and easily customizable alert message.
+group: components
+toc: true
+---
+
+Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems. They're built with flexbox, so they're easy to align and position.
+
+## Overview
+
+Things to know when using the toast plugin:
+
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+- Toasts are opt-in for performance reasons, so **you must initialize them yourself**.
+- **Please note that you are responsible for positioning toasts.**
+- Toasts will automatically hide if you do not specify `autohide: false`.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+## Examples
+
+### Basic
+
+To encourage extensible and predictable toasts, we recommend a header and body. Toast headers use `display: flex`, allowing easy alignment of content thanks to our margin and flexbox utilities.
+
+Toasts are as flexible as you need and have very little required markup. At a minimum, we require a single element to contain your "toasted" content and strongly encourage a dismiss button.
+
+{{< example class="bg-light" >}}
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text=" " title=" " >}}
+    <strong class="mr-auto">Bootstrap</strong>
+    <small>11 mins ago</small>
+    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+      <span aria-hidden="true">&times;</span>
+    </button>
+  </div>
+  <div class="toast-body">
+    Hello, world! This is a toast message.
+  </div>
+</div>
+{{< /example >}}
+
+### Live
+
+Click the button the below to show as toast (positioning with our utilities in the lower right corner) that has been hidden by default with `.hide`.
+
+<div class="position-fixed bottom-0 right-0 p-3" style="z-index: 5; right: 0; bottom: 0;">
+  <div id="liveToast" class="toast hide" role="alert" aria-live="assertive" aria-atomic="true" data-delay="2000">
+    <div class="toast-header">
+      {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text="false" title="false" >}}
+      <strong class="mr-auto">Bootstrap</strong>
+      <small>11 mins ago</small>
+      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+        <span aria-hidden="true">&times;</span>
+      </button>
+    </div>
+    <div class="toast-body">
+      Hello, world! This is a toast message.
+    </div>
+  </div>
+</div>
+
+<div class="bd-example">
+  <button type="button" class="btn btn-primary" id="liveToastBtn">Show live toast</button>
+</div>
+
+```html
+<button type="button" class="btn btn-primary" id="liveToastBtn">Show live toast</button>
+
+<div class="position-fixed bottom-0 right-0 p-3" style="z-index: 5; right: 0; bottom: 0;">
+  <div id="liveToast" class="toast hide" role="alert" aria-live="assertive" aria-atomic="true" data-delay="2000">
+    <div class="toast-header">
+      <img src="..." class="rounded mr-2" alt="...">
+      <strong class="mr-auto">Bootstrap</strong>
+      <small>11 mins ago</small>
+      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+        <span aria-hidden="true">&times;</span>
+      </button>
+    </div>
+    <div class="toast-body">
+      Hello, world! This is a toast message.
+    </div>
+  </div>
+</div>
+```
+
+### Translucent
+
+Toasts are slightly translucent, too, so they blend over whatever they might appear over. For browsers that support the `backdrop-filter` CSS property, we'll also attempt to blur the elements under a toast.
+
+{{< example class="bg-dark" >}}
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text=" " title=" " >}}
+    <strong class="mr-auto">Bootstrap</strong>
+    <small class="text-muted">11 mins ago</small>
+    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+      <span aria-hidden="true">&times;</span>
+    </button>
+  </div>
+  <div class="toast-body">
+    Hello, world! This is a toast message.
+  </div>
+</div>
+{{< /example >}}
+
+### Stacking
+
+When you have multiple toasts, we default to vertically stacking them in a readable manner.
+
+{{< example class="bg-light" >}}
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text=" " title=" " >}}
+    <strong class="mr-auto">Bootstrap</strong>
+    <small class="text-muted">just now</small>
+    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+      <span aria-hidden="true">&times;</span>
+    </button>
+  </div>
+  <div class="toast-body">
+    See? Just like this.
+  </div>
+</div>
+
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text=" " title=" " >}}
+    <strong class="mr-auto">Bootstrap</strong>
+    <small class="text-muted">2 seconds ago</small>
+    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+      <span aria-hidden="true">&times;</span>
+    </button>
+  </div>
+  <div class="toast-body">
+    Heads up, toasts will stack automatically
+  </div>
+</div>
+{{< /example >}}
+
+## Placement
+
+Place toasts with custom CSS as you need them. The top right is often used for notifications, as is the top middle. If you're only ever going to show one toast at a time, put the positioning styles right on the `.toast`.
+
+{{< example class="bg-dark" >}}
+<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
+  <div class="toast" style="position: absolute; top: 0; right: 0;">
+    <div class="toast-header">
+      {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text=" " title=" " >}}
+      <strong class="mr-auto">Bootstrap</strong>
+      <small>11 mins ago</small>
+      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+        <span aria-hidden="true">&times;</span>
+      </button>

+
+For systems that generate more notifications, consider using a wrapping element so they can easily stack.
+
+{{< example class="bg-dark" >}}
+<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
+  <!-- Position it -->
+  <div style="position: absolute; top: 0; right: 0;">

+
+## Accessibility
+
+Toasts are intended to be small interruptions to your visitors or users, so to help those with screen readers and similar assistive technologies, you should wrap your toasts in an [`aria-live` region](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Live_Regions). Changes to live regions (such as injecting/updating a toast component) are automatically announced by screen readers without needing to move the user's focus or otherwise interrupt the user. Additionally, include `aria-atomic="true"` to ensure that the entire toast is always announced as a single (atomic) unit, rather than announcing what was changed (which could lead to problems if you only update part of the toast's content, or if displaying the same toast content at a later point in time). If the information needed is important for the process, e.g. for a list of errors in a form, then use the [alert component]({{< docsref "/components/alerts" >}}) instead of toast.
+
+Note that the live region needs to be present in the markup *before* the toast is generated or updated. If you dynamically generate both at the same time and inject them into the page, they will generally not be announced by assistive technologies.
+
+You also need to adapt the `role` and `aria-live` level depending on the content. If it's an important message like an error, use `role="alert" aria-live="assertive"`, otherwise use `role="status" aria-live="polite"` attributes.
+
+As the content you're displaying changes, be sure to update the [`delay` timeout](#options) to ensure people have enough time to read the toast.
+
+```html
+<div class="toast" role="alert" aria-live="polite" aria-atomic="true" data-delay="10000">
+  <div role="alert" aria-live="assertive" aria-atomic="true">...</div>
+</div>
+```
+
+When using `autohide: false`, you must add a close button to allow users to dismiss the toast.
+
+{{< example class="bg-light" >}}
+<div role="alert" aria-live="assertive" aria-atomic="true" class="toast" data-autohide="false">
+  <div class="toast-header">
+    {{< placeholder width="20" height="20" background="#007aff" class="rounded mr-2" text=" " title=" " >}}
+    <strong class="mr-auto">Bootstrap</strong>
+    <small>11 mins ago</small>
+    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
+      <span aria-hidden="true">&times;</span>
+    </button>
+  </div>
+  <div class="toast-body">
+    Hello, world! This is a toast message.
+  </div>
+</div>
+{{< /example >}}
+
+## JavaScript behavior
+
+### Usage
+
+Initialize toasts via JavaScript:
+
+```js
+$('.toast').toast(option)
+```
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 100px;">Name</th>
+      <th style="width: 100px;">Type</th>
+      <th style="width: 50px;">Default</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>animation</td>
+      <td>boolean</td>
+      <td>true</td>
+      <td>Apply a CSS fade transition to the toast</td>
+    </tr>
+    <tr>
+      <td>autohide</td>
+      <td>boolean</td>
+      <td>true</td>
+      <td>Auto hide the toast</td>
+    </tr>
+    <tr>
+      <td>delay</td>
+      <td>number</td>
+      <td>
+        <code>500</code>

+
+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### `$().toast(options)`
+
+Attaches a toast handler to an element collection.
+
+#### `.toast('show')`
+
+Reveals an element's toast. **Returns to the caller before the toast has actually been shown** (i.e. before the `shown.bs.toast` event occurs).
+You have to manually call this method, instead your toast won't show.
+
+```js
+$('#element').toast('show')
+```
+
+#### `.toast('hide')`
+
+Hides an element's toast. **Returns to the caller before the toast has actually been hidden** (i.e. before the `hidden.bs.toast` event occurs). You have to manually call this method if you made `autohide` to `false`.
+
+```js
+$('#element').toast('hide')
+```
+
+#### `.toast('dispose')`
+
+Hides an element's toast. Your toast will remain on the DOM but won't show anymore.
+
+```js
+$('#element').toast('dispose')
+```
+
+### Events
+
+<table class="table table-bordered table-striped">
+  <thead>
+    <tr>
+      <th style="width: 150px;">Event Type</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>show.bs.toast</td>

+    </tr>
+    <tr>
+      <td>hide.bs.toast</td>
+      <td>This event is fired immediately when the <code>hide</code> instance method has been called.</td>
+    </tr>
+    <tr>
+      <td>hidden.bs.toast</td>

+
+## Overview
+
+Things to know when using the tooltip plugin:
+
+- Tooltips rely on the 3rd party library [Popper](https://popper.js.org/) for positioning. You must include [popper.min.js]({{< param "cdn.popper" >}}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper in order for tooltips to work!
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}).
+- Tooltips are opt-in for performance reasons, so **you must initialize them yourself**.
+- Tooltips with zero-length titles are never displayed.
+- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
+- Triggering tooltips on hidden elements will not work.
+- Tooltips for `.disabled` or `disabled` elements must be triggered on a wrapper element.
+- When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use `white-space: nowrap;` on your `<a>`s to avoid this behavior.
+- Tooltips must be hidden before their corresponding elements have been removed from the DOM.
+- Tooltips can be triggered thanks to an element inside a shadow DOM.
+
+{{< callout info >}}
+{{< partial "callout-info-prefersreducedmotion.md" >}}
+{{< /callout >}}
+
+Got all that? Great, let's see how they work with some examples.
+
+## Example: Enable tooltips everywhere
+
+One way to initialize all tooltips on a page would be to select them by their `data-toggle` attribute:
+
+```js
+$(function () {
+  $('[data-toggle="tooltip"]').tooltip()
+})
+```
+
+## Examples
+
+Hover over the links below to see tooltips:
+
+<div class="bd-example tooltip-demo">
+  <p class="muted">Placeholder text to demonstrate some <a href="#" data-toggle="tooltip" title="Default tooltip">inline links</a> with tooltips. This is now just filler, no killer. Content placed here just to mimic the presence of <a href="#" data-toggle="tooltip" title="Another tooltip">real text</a>. And all that just to give you an idea of how tooltips would look when used in real-world situations. So hopefully you've now seen how <a href="#" data-toggle="tooltip" title="Another one here too">these tooltips on links</a> can work in practice, once you use them on <a href="#" data-toggle="tooltip" title="The last tip!">your own</a> site or project.
+  </p>
+</div>
+
+Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left.
+
+<div class="bd-example tooltip-demo">
+  <div class="bd-example-tooltips">
+    <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>
+    <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>
+    <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">Tooltip on bottom</button>
+    <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>
+    <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">Tooltip with HTML</button>
+  </div>
+</div>
+
+```html
+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">
+  Tooltip on top
+</button>
+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">
+  Tooltip on right
+</button>
+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">
+  Tooltip on bottom
+</button>
+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">
+  Tooltip on left
+</button>
+```
+
+And with custom HTML added:
+
+```html
+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
+  Tooltip with HTML
+</button>
+```
+
+## Usage
+
+The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
+
+Trigger the tooltip via JavaScript:
+
+```js
+$('#example').tooltip(options)
+```
+
+{{< callout warning >}}
+##### Overflow `auto` and `scroll`
+
+Tooltip position attempts to automatically change when a parent container has `overflow: auto` or `overflow: scroll` like our `.table-responsive`, but still keeps the original placement's positioning. To resolve, set the `boundary` option to anything other than default value, `'scrollParent'`, such as `'window'`:
+
+```js
+$('#example').tooltip({ boundary: 'window' })
+```
+{{< /callout >}}
+
+### Markup
+
+The required markup for a tooltip is only a `data` attribute and `title` on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to `top` by the plugin).
+
+{{< callout warning >}}
+##### Making tooltips work for keyboard and assistive technology users
+
+You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as `<span>`s) can be made focusable by adding the `tabindex="0"` attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users, and most assistive technologies currently do not announce the tooltip in this situation. Additionally, do not rely solely on `hover` as the trigger for your tooltip, as this will make your tooltips impossible to trigger for keyboard users.
+{{< /callout >}}
+
+```html
+<!-- HTML to write -->
+<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
+
+<!-- Generated markup by the plugin -->
+<div class="tooltip bs-tooltip-top" role="tooltip">
+  <div class="arrow"></div>
+  <div class="tooltip-inner">
+    Some tooltip text!
+  </div>
+</div>
+```
+
+### Disabled elements
+
+Elements with the `disabled` attribute aren't interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you'll want to trigger the tooltip from a wrapper `<div>` or `<span>`, ideally made keyboard-focusable using `tabindex="0"`, and override the `pointer-events` on the disabled element.
+
+<div class="tooltip-demo">
+{{< example >}}
+<span class="d-inline-block" tabindex="0" data-toggle="tooltip" title="Disabled tooltip">
+  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
+</span>
+{{< /example >}}
+</div>
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.
+
+{{< callout warning >}}
+Note that for security reasons the `sanitize`, `sanitizeFn` and `whiteList` options cannot be supplied using data attributes.
+{{< /callout >}}

+### Methods
+
+{{< callout danger >}}
+{{< partial "callout-danger-async-methods.md" >}}
+{{< /callout >}}
+
+#### `$().tooltip(options)`
+
+Attaches a tooltip handler to an element collection.
+
+#### `.tooltip('show')`
+
+Reveals an element's tooltip. **Returns to the caller before the tooltip has actually been shown** (i.e. before the `shown.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.
+
+```js
+$('#element').tooltip('show')
+```
+
+#### `.tooltip('hide')`
+
+Hides an element's tooltip. **Returns to the caller before the tooltip has actually been hidden** (i.e. before the `hidden.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip.
+
+```js
+$('#element').tooltip('hide')
+```
+
+#### `.tooltip('toggle')`
+
+Toggles an element's tooltip. **Returns to the caller before the tooltip has actually been shown or hidden** (i.e. before the `shown.bs.tooltip` or `hidden.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip.
+
+```js
+$('#element').tooltip('toggle')
+```
+
+#### `.tooltip('dispose')`
+
+Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.
+
+```js
+$('#element').tooltip('dispose')
+```
+
+#### `.tooltip('enable')`
+
+Gives an element's tooltip the ability to be shown. **Tooltips are enabled by default.**
+
+```js
+$('#element').tooltip('enable')
+```
+
+#### `.tooltip('disable')`
+
+Removes the ability for an element's tooltip to be shown. The tooltip will only be able to be shown if it is re-enabled.
+
+```js
+$('#element').tooltip('disable')
+```
+
+#### `.tooltip('toggleEnabled')`
+
+Toggles the ability for an element's tooltip to be shown or hidden.
+
+```js
+$('#element').tooltip('toggleEnabled')
+```
+
+#### `.tooltip('update')`
+
+Updates the position of an element's tooltip.
+
+```js
+$('#element').tooltip('update')
+```

+
+## Inline code
+
+Wrap inline snippets of code with `<code>`. Be sure to escape HTML angle brackets.
+
+{{< example >}}
+For example, <code>&lt;section&gt;</code> should be wrapped as inline.
+{{< /example >}}
+
+## Code blocks
+
+Use `<pre>`s for multiple lines of code. Once again, be sure to escape any angle brackets in the code for proper rendering. You may optionally add the `.pre-scrollable` class, which will set a max-height of 340px and provide a y-axis scrollbar.
+
+{{< example >}}
+<pre><code>&lt;p&gt;Sample text here...&lt;/p&gt;
+&lt;p&gt;And another line of sample text here...&lt;/p&gt;
+</code></pre>
+{{< /example >}}
+
+## Variables
+
+For indicating variables use the `<var>` tag.
+
+{{< example >}}
+<var>y</var> = <var>m</var><var>x</var> + <var>b</var>
+{{< /example >}}
+
+## User input
+
+Use the `<kbd>` to indicate input that is typically entered via keyboard.
+
+{{< example >}}
+To switch directories, type <kbd>cd</kbd> followed by the name of the directory.<br>
+To edit settings, press <kbd><kbd>ctrl</kbd> + <kbd>,</kbd></kbd>
+{{< /example >}}
+
+## Sample output
+
+For indicating sample output from a program use the `<samp>` tag.
+
+{{< example >}}
+<samp>This text is meant to be treated as sample output from a computer program.</samp>
+{{< /example >}}

+description: Documentation and examples for displaying related images and text with the figure component in Bootstrap.
+group: content
+---
+
+Anytime you need to display a piece of content—like an image with an optional caption, consider using a `<figure>`.
+
+Use the included `.figure` , `.figure-img` and `.figure-caption` classes to provide some baseline styles for the HTML5 `<figure>` and `<figcaption>` elements. Images in figures have no explicit size, so be sure to add the `.img-fluid` class to your `<img>` to make it responsive.
+
+{{< example >}}
+<figure class="figure">
+  {{< placeholder width="400" height="300" class="figure-img img-fluid rounded" >}}
+  <figcaption class="figure-caption">A caption for the above image.</figcaption>
+</figure>
+{{< /example >}}
+
+Aligning the figure's caption is easy with our [text utilities]({{< docsref "/utilities/text#text-alignment" >}}).
+
+{{< example >}}
+<figure class="figure">
+  {{< placeholder width="400" height="300" class="figure-img img-fluid rounded" >}}

+title: Images
+description: Documentation and examples for opting images into responsive behavior (so they never become larger than their parent elements) and add lightweight styles to them—all via classes.
+group: content
+toc: true
+---
+
+## Responsive images
+
+Images in Bootstrap are made responsive with `.img-fluid`. `max-width: 100%;` and `height: auto;` are applied to the image so that it scales with the parent element.
+
+{{< example >}}
+{{< placeholder width="100%" height="250" class="bd-placeholder-img-lg img-fluid" text="Responsive image" >}}
+{{< /example >}}
+
+{{< callout warning >}}
+##### SVG images and Internet Explorer
+
+In Internet Explorer 10 and 11, SVG images with `.img-fluid` are disproportionately sized. To fix this, add `width: 100%;` or `.w-100` where necessary. This fix improperly sizes other image formats, so Bootstrap doesn't apply it automatically.
+{{< /callout >}}
+
+## Image thumbnails
+
+In addition to our [border-radius utilities]({{< docsref "/utilities/borders" >}}), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.
+
+{{< example >}}
+{{< placeholder width="200" height="200" class="img-thumbnail" title="A generic square placeholder image with a white border around it, making it resemble a photograph taken with an old instant camera" >}}
+{{< /example >}}
+
+## Aligning images
+
+Align images with the [helper float classes]({{< docsref "/utilities/float" >}}) or [text alignment classes]({{< docsref "/utilities/text#text-alignment" >}}). `block`-level images can be centered using [the `.mx-auto` margin utility class]({{< docsref "/utilities/spacing#horizontal-centering" >}}).
+
+{{< example >}}
+{{< placeholder width="200" height="200" class="rounded float-left" >}}
+{{< placeholder width="200" height="200" class="rounded float-right" >}}
+{{< /example >}}
+
+{{< example >}}
+{{< placeholder width="200" height="200" class="rounded mx-auto d-block" >}}
+{{< /example >}}
+
+{{< example >}}
+<div class="text-center">
+  {{< placeholder width="200" height="200" class="rounded" >}}
+</div>
+{{< /example >}}
+
+
+## Picture
+
+If you are using the `<picture>` element to specify multiple `<source>` elements for a specific `<img>`, make sure to add the `.img-*` classes to the `<img>` and not to the `<picture>` tag.
+
+```html
+​<picture>
+  <source srcset="..." type="image/svg+xml">
+  <img src="..." class="img-fluid img-thumbnail" alt="...">

+title: Reboot
+description: Reboot, a collection of element-specific CSS changes in a single file, kickstart Bootstrap to provide an elegant, consistent, and simple baseline to build upon.
+group: content
+aliases: "/docs/4.6/content/"
+toc: true
+---
+
+## Approach
+
+Reboot builds upon Normalize, providing many HTML elements with somewhat opinionated styles using only element selectors. Additional styling is done only with classes. For example, we reboot some `<table>` styles for a simpler baseline and later provide `.table`, `.table-bordered`, and more.
+
+Here are our guidelines and reasons for choosing what to override in Reboot:
+
+- Update some browser default values to use `rem`s instead of `em`s for scalable component spacing.
+- Avoid `margin-top`. Vertical margins can collapse, yielding unexpected results. More importantly though, a single direction of `margin` is a simpler mental model.
+- For easier scaling across device sizes, block elements should use `rem`s for `margin`s.
+- Keep declarations of `font`-related properties to a minimum, using `inherit` whenever possible.
+
+## Page defaults
+
+The `<html>` and `<body>` elements are updated to provide better page-wide defaults. More specifically:
+
+- The `box-sizing` is globally set on every element—including `*::before` and `*::after`, to `border-box`. This ensures that the declared width of element is never exceeded due to padding or border.
+- No base `font-size` is declared on the `<html>`, but `16px` is assumed (the browser default). `font-size: 1rem` is applied on the `<body>` for easy responsive type-scaling via media queries while respecting user preferences and ensuring a more accessible approach.
+- The `<body>` also sets a global `font-family`, `line-height`, and `text-align`. This is inherited later by some form elements to prevent font inconsistencies.
+- For safety, the `<body>` has a declared `background-color`, defaulting to `#fff`.
+
+## Native font stack
+
+The default web fonts (Helvetica Neue, Helvetica, and Arial) have been dropped in Bootstrap 4 and replaced with a "native font stack" for optimum text rendering on every device and OS. Read more about [native font stacks in this *Smashing Magazine* article](https://www.smashingmagazine.com/2015/11/using-system-ui-fonts-practical-guide/).
+
+```scss
+$font-family-sans-serif:
+  // Safari for macOS and iOS (San Francisco)
+  -apple-system,
+  // Chrome < 56 for macOS (San Francisco)
+  BlinkMacSystemFont,
+  // Windows
+  "Segoe UI",
+  // Android
+  Roboto,
+  // Basic web fallback
+  "Helvetica Neue", Arial,
+  // Linux
+  "Noto Sans",
+  "Liberation Sans",
+  // Sans serif fallback
+  sans-serif,
+  // Emoji fonts
+  "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji" !default;
+```
+
+Note that because the font stack includes emoji fonts, many common symbol/dingbat unicode characters will be rendered as multi-colored pictographs. Their appearance will vary, depending on the style used in the browser/platform's native emoji font, and they won't be affected by any CSS `color` styles.
+
+This `font-family` is applied to the `<body>` and automatically inherited globally throughout Bootstrap. To switch the global `font-family`, update `$font-family-base` and recompile Bootstrap.
+
+## Headings and paragraphs
+
+All heading elements—e.g., `<h1>`—and `<p>` are reset to have their `margin-top` removed. Headings have `margin-bottom: .5rem` added and paragraphs `margin-bottom: 1rem` for easy spacing.
+
+<table>
+  <thead>
+    <tr>
+      <th>Heading</th>
+      <th>Example</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>
+        {{< markdown >}}`<h1></h1>`{{< /markdown >}}
+      </td>
+      <td><span class="h1">h1. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h2></h2>`{{< /markdown >}}
+      </td>
+      <td><span class="h2">h2. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h3></h3>`{{< /markdown >}}
+      </td>
+      <td><span class="h3">h3. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h4></h4>`{{< /markdown >}}
+      </td>
+      <td><span class="h4">h4. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h5></h5>`{{< /markdown >}}
+      </td>
+      <td><span class="h5">h5. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h6></h6>`{{< /markdown >}}
+      </td>
+      <td><span class="h6">h6. Bootstrap heading</span></td>
+    </tr>
+  </tbody>
+</table>
+
+## Lists
+
+All lists—`<ul>`, `<ol>`, and `<dl>`—have their `margin-top` removed and a `margin-bottom: 1rem`. Nested lists have no `margin-bottom`.
+
+<div class="bd-example">
+{{< markdown >}}
+* All lists have their top margin removed
+* And their bottom margin normalized
+* Nested lists have no bottom margin
+  * This way they have a more even appearance
+  * Particularly when followed by more list items
+* The left padding has also been reset
+
+1. Here's an ordered list
+2. With a few list items
+3. It has the same overall look
+4. As the previous unordered list
+{{< /markdown >}}
+</div>
+
+For simpler styling, clear hierarchy, and better spacing, description lists have updated `margin`s. `<dd>`s reset `margin-left` to `0` and add `margin-bottom: .5rem`. `<dt>`s are **bolded**.
+
+<div class="bd-example">
+  <dl>
+    <dt>Description lists</dt>
+    <dd>A description list is perfect for defining terms.</dd>
+    <dt>Term</dt>
+    <dd>Definition for the term.</dd>
+    <dd>A second definition for the same term.</dd>
+    <dt>Another term</dt>
+    <dd>Definition for this other term.</dd>
+  </dl>
+</div>
+
+## Preformatted text
+
+The `<pre>` element is reset to remove its `margin-top` and use `rem` units for its `margin-bottom`.
+
+<div class="bd-example">
+<pre>
+.example-element {
+  margin-bottom: 1rem;
+}
+</pre>
+</div>
+
+## Tables
+
+Tables are slightly adjusted to style `<caption>`s, collapse borders, and ensure consistent `text-align` throughout. Additional changes for borders, padding, and more come with [the `.table` class]({{< docsref "/content/tables" >}}).
+
+<div class="bd-example">
+  <table>
+    <caption>
+      This is an example table, and this is its caption to describe the contents.
+    </caption>
+    <thead>
+      <tr>
+        <th>Table heading</th>
+        <th>Table heading</th>
+        <th>Table heading</th>
+        <th>Table heading</th>
+      </tr>
+    </thead>
+    <tbody>
+      <tr>
+        <td>Table cell</td>
+        <td>Table cell</td>
+        <td>Table cell</td>
+        <td>Table cell</td>
+      </tr>
+      <tr>
+        <td>Table cell</td>
+        <td>Table cell</td>
+        <td>Table cell</td>
+        <td>Table cell</td>
+      </tr>
+      <tr>
+        <td>Table cell</td>
+        <td>Table cell</td>
+        <td>Table cell</td>
+        <td>Table cell</td>
+      </tr>
+    </tbody>
+  </table>
+</div>
+
+## Forms
+
+Various form elements have been rebooted for simpler base styles. Here are some of the most notable changes:
+
+- `<fieldset>`s have no borders, padding, or margin so they can be easily used as wrappers for individual inputs or groups of inputs.
+- `<legend>`s, like fieldsets, have also been restyled to be displayed as a heading of sorts.
+- `<label>`s are set to `display: inline-block` to allow `margin` to be applied.
+- `<input>`s, `<select>`s, `<textarea>`s, and `<button>`s are mostly addressed by Normalize, but Reboot removes their `margin` and sets `line-height: inherit`, too.
+- `<textarea>`s are modified to only be resizable vertically as horizontal resizing often "breaks" page layout.
+- `<button>`s and `<input>` button elements have `cursor: pointer` when `:not(:disabled)`.
+
+These changes, and more, are demonstrated below.
+
+<form class="bd-example">
+  <fieldset>
+    <legend>Example legend</legend>
+    <p>
+      <label for="input">Example input</label>
+      <input type="text" id="input" placeholder="Example input">

+      </label>
+      <label>
+        <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
+        Option two is something else that's also super long to demonstrate the wrapping of these fancy form controls.

+      <input type="button" value="Input button" disabled>
+    </p>
+  </fieldset>
+</form>
+
+### Pointers on buttons
+
+Reboot includes an enhancement for `role="button"` to change the default cursor to `pointer`. Add this attribute to elements to help indicate elements are interactive. This role isn't necessary for `<button>` elements, which get their own `cursor` change.
+
+{{< example >}}
+<span role="button" tabindex="0">Non-button element button</span>
+{{< /example >}}
+
+## Misc elements
+
+### Address
+
+The `<address>` element is updated to reset the browser default `font-style` from `italic` to `normal`. `line-height` is also now inherited, and `margin-bottom: 1rem` has been added. `<address>`s are for presenting contact information for the nearest ancestor (or an entire body of work). Preserve formatting by ending lines with `<br>`.
+
+<div class="bd-example">
+  <address>
+    <strong>Twitter, Inc.</strong><br>
+    1355 Market St, Suite 900<br>
+    San Francisco, CA 94103<br>
+    <abbr title="Phone">P:</abbr> (123) 456-7890
+  </address>
+
+  <address>
+    <strong>Full Name</strong><br>
+    <a href="mailto:first.last@example.com">first.last@example.com</a>
+  </address>
+</div>
+
+### Blockquote
+
+The default `margin` on blockquotes is `1em 40px`, so we reset that to `0 0 1rem` for something more consistent with other elements.
+
+<div class="bd-example">
+  <blockquote class="blockquote">
+    <p>A well-known quote, contained in a blockquote element.</p>
+    <footer>Someone famous in <cite title="Source Title">Source Title</cite></footer>
+  </blockquote>
+</div>
+
+### Inline elements
+
+The `<abbr>` element receives basic styling to make it stand out amongst paragraph text.
+
+<div class="bd-example">
+  Nulla <abbr title="attribute">attr</abbr> vitae elit libero, a pharetra augue.
+</div>
+
+### Summary
+
+The default `cursor` on summary is `text`, so we reset that to `pointer` to convey that the element can be interacted with by clicking on it.
+
+<div class="bd-example">
+  <details>
+    <summary>Some details</summary>
+    <p>More info about the details.</p>
+  </details>

+## HTML5 `[hidden]` attribute
+
+HTML5 adds [a new global attribute named `[hidden]`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden), which is styled as `display: none` by default. Borrowing an idea from [PureCSS](https://purecss.io/), we improve upon this default by making `[hidden] { display: none !important; }` to help prevent its `display` from getting accidentally overridden. While `[hidden]` isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem.
+
+```html
+<input type="text" hidden>
+```
+
+{{< callout warning >}}
+##### jQuery incompatibility
+
+`[hidden]` is not compatible with jQuery's `$(...).hide()` and `$(...).show()` methods. Therefore, we don't currently especially endorse `[hidden]` over other techniques for managing the `display` of elements.
+{{< /callout >}}
+
+To merely toggle the visibility of an element, meaning its `display` is not modified and the element can still affect the flow of the document, use [the `.invisible` class]({{< docsref "/utilities/visibility" >}}) instead.

+title: Tables
+description: Documentation and examples for opt-in styling of tables (given their prevalent use in JavaScript plugins) with Bootstrap.
+group: content
+toc: true
+---
+
+## Examples
+
+Due to the widespread use of tables across third-party widgets like calendars and date pickers, we've designed our tables to be **opt-in**. Just add the base class `.table` to any `<table>`, then extend with custom styles or our various included modifier classes.
+
+Using the most basic table markup, here's how `.table`-based tables look in Bootstrap. **All table styles are inherited in Bootstrap 4**, meaning any nested tables will be styled in the same manner as the parent.
+
+{{< example >}}
+<table class="table">
+  <thead>
+    <tr>
+      <th scope="col">#</th>
+      <th scope="col">First</th>
+      <th scope="col">Last</th>
+      <th scope="col">Handle</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <th scope="row">1</th>
+      <td>Mark</td>
+      <td>Otto</td>
+      <td>@mdo</td>
+    </tr>
+    <tr>
+      <th scope="row">2</th>
+      <td>Jacob</td>
+      <td>Thornton</td>
+      <td>@fat</td>
+    </tr>
+    <tr>
+      <th scope="row">3</th>
+      <td>Larry</td>
+      <td>the Bird</td>
+      <td>@twitter</td>
+    </tr>
+  </tbody>
+</table>
+{{< /example >}}
+
+You can also invert the colors—with light text on dark backgrounds—with `.table-dark`.
+
+{{< example >}}
+<table class="table table-dark">
+  <thead>
+    <tr>
+      <th scope="col">#</th>
+      <th scope="col">First</th>
+      <th scope="col">Last</th>
+      <th scope="col">Handle</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <th scope="row">1</th>
+      <td>Mark</td>
+      <td>Otto</td>
+      <td>@mdo</td>
+    </tr>
+    <tr>
+      <th scope="row">2</th>
+      <td>Jacob</td>
+      <td>Thornton</td>
+      <td>@fat</td>
+    </tr>
+    <tr>
+      <th scope="row">3</th>
+      <td>Larry</td>
+      <td>the Bird</td>
+      <td>@twitter</td>
+    </tr>
+  </tbody>
+</table>
+{{< /example >}}
+
+## Table head options
+
+Similar to tables and dark tables, use the modifier classes `.thead-light` or `.thead-dark` to make `<thead>`s appear light or dark gray.
+
+{{< example >}}
+<table class="table">
+  <thead class="thead-dark">
+    <tr>
+      <th scope="col">#</th>
+      <th scope="col">First</th>
+      <th scope="col">Last</th>
+      <th scope="col">Handle</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <th scope="row">1</th>
+      <td>Mark</td>
+      <td>Otto</td>
+      <td>@mdo</td>
+    </tr>
+    <tr>
+      <th scope="row">2</th>
+      <td>Jacob</td>
+      <td>Thornton</td>
+      <td>@fat</td>
+    </tr>
+    <tr>
+      <th scope="row">3</th>
+      <td>Larry</td>
+      <td>the Bird</td>
+      <td>@twitter</td>
+    </tr>
+  </tbody>
+</table>
+
+<table class="table">
+  <thead class="thead-light">
+    <tr>
+      <th scope="col">#</th>
+      <th scope="col">First</th>

+      <th scope="col">Handle</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <th scope="row">1</th>

+A `<caption>` functions like a heading for a table. It helps users with screen readers to find a table and understand what it's about and decide if they want to read it.

+## Responsive tables
+
+Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a `.table` with `.table-responsive`. Or, pick a maximum breakpoint with which to have a responsive table up to by using `.table-responsive{-sm|-md|-lg|-xl}`.
+
+{{< callout warning >}}
+##### Vertical clipping/truncation
+
+Responsive tables make use of `overflow-y: hidden`, which clips off any content that goes beyond the bottom or top edges of the table. In particular, this can clip off dropdown menus and other third-party widgets.
+{{< /callout >}}
+
+### Always responsive
+
+Across every breakpoint, use `.table-responsive` for horizontally scrolling tables.

+title: Typography
+description: Documentation and examples for Bootstrap typography, including global settings, headings, body text, lists, and more.
+group: content
+toc: true
+---
+
+## Global settings
+
+Bootstrap sets basic global display, typography, and link styles. When more control is needed, check out the [textual utility classes]({{< docsref "/utilities/text" >}}).
+
+- Use a [native font stack]({{< docsref "/content/reboot#native-font-stack" >}}) that selects the best `font-family` for each OS and device.
+- For a more inclusive and accessible type scale, we use the browser's default root `font-size` (typically 16px) so visitors can customize their browser defaults as needed.
+- Use the `$font-family-base`, `$font-size-base`, and `$line-height-base` attributes as our typographic base applied to the `<body>`.
+- Set the global link color via `$link-color` and apply link underlines only on `:hover`.
+- Use `$body-bg` to set a `background-color` on the `<body>` (`#fff` by default).
+
+These styles can be found within `_reboot.scss`, and the global variables are defined in `_variables.scss`. Make sure to set `$font-size-base` in `rem`.
+
+## Headings
+
+All HTML headings, `<h1>` through `<h6>`, are available.
+
+<table>
+  <thead>
+    <tr>
+      <th>Heading</th>
+      <th>Example</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>
+        {{< markdown >}}`<h1></h1>`{{< /markdown >}}
+      </td>
+      <td><span class="h1">h1. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h2></h2>`{{< /markdown >}}
+      </td>
+      <td><span class="h2">h2. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h3></h3>`{{< /markdown >}}
+      </td>
+      <td><span class="h3">h3. Bootstrap heading</span></td>
+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h4></h4>`{{< /markdown >}}
+      </td>
+      <td><span class="h4">h4. Bootstrap heading</span></td>

+      </td>

+    </tr>
+    <tr>
+      <td>
+        {{< markdown >}}`<h6></h6>`{{< /markdown >}}
+      </td>
+      <td><span class="h6">h6. Bootstrap heading</span></td>
+    </tr>
+  </tbody>
+</table>
+
+```html
+<h1>h1. Bootstrap heading</h1>
+<h2>h2. Bootstrap heading</h2>
+<h3>h3. Bootstrap heading</h3>
+<h4>h4. Bootstrap heading</h4>
+<h5>h5. Bootstrap heading</h5>
+<h6>h6. Bootstrap heading</h6>
+```
+
+`.h1` through `.h6` classes are also available, for when you want to match the font styling of a heading but cannot use the associated HTML element.
+
+{{< example >}}
+<p class="h1">h1. Bootstrap heading</p>
+<p class="h2">h2. Bootstrap heading</p>
+<p class="h3">h3. Bootstrap heading</p>
+<p class="h4">h4. Bootstrap heading</p>
+<p class="h5">h5. Bootstrap heading</p>
+<p class="h6">h6. Bootstrap heading</p>
+{{< /example >}}
+
+### Customizing headings
+
+Use the included utility classes to recreate the small secondary heading text from Bootstrap 3.
+
+{{< example >}}
+<h3>
+  Fancy display heading
+  <small class="text-muted">With faded secondary text</small>
+</h3>
+{{< /example >}}
+
+## Display headings
+
+Traditional heading elements are designed to work best in the meat of your page content. When you need a heading to stand out, consider using a **display heading**—a larger, slightly more opinionated heading style. Keep in mind these headings are not responsive by default, but it's possible to enable [responsive font sizes](#responsive-font-sizes).
+
+<div class="bd-example bd-example-type">
+  <table class="table">
+    <tbody>
+      <tr>
+        <td><span class="display-1">Display 1</span></td>
+      </tr>
+      <tr>
+      <td><span class="display-2">Display 2</span></td>
+      </tr>
+      <tr>
+      <td><span class="display-3">Display 3</span></td>
+      </tr>
+      <tr>
+      <td><span class="display-4">Display 4</span></td>
+      </tr>
+    </tbody>
+  </table>
+</div>
+
+```html
+<h1 class="display-1">Display 1</h1>
+<h1 class="display-2">Display 2</h1>
+<h1 class="display-3">Display 3</h1>
+<h1 class="display-4">Display 4</h1>
+```
+
+## Lead
+
+Make a paragraph stand out by adding `.lead`.
+
+{{< example >}}
+<p class="lead">
+  This is a lead paragraph. It stands out from regular paragraphs.
+</p>
+{{< /example >}}
+
+## Inline text elements
+
+Styling for common inline HTML5 elements.
+
+{{< example >}}
+<p>You can use the mark tag to <mark>highlight</mark> text.</p>
+<p><del>This line of text is meant to be treated as deleted text.</del></p>
+<p><s>This line of text is meant to be treated as no longer accurate.</s></p>
+<p><ins>This line of text is meant to be treated as an addition to the document.</ins></p>
+<p><u>This line of text will render as underlined</u></p>
+<p><small>This line of text is meant to be treated as fine print.</small></p>
+<p><strong>This line rendered as bold text.</strong></p>
+<p><em>This line rendered as italicized text.</em></p>
+{{< /example >}}
+
+`.mark` and `.small` classes are also available to apply the same styles as `<mark>` and `<small>` while avoiding any unwanted semantic implications that the tags would bring.
+
+While not shown above, feel free to use `<b>` and `<i>` in HTML5. `<b>` is meant to highlight words or phrases without conveying additional importance while `<i>` is mostly for voice, technical terms, etc.
+
+## Text utilities
+
+Change text alignment, transform, style, weight, and color with our [text utilities]({{< docsref "/utilities/text" >}}) and [color utilities]({{< docsref "/utilities/colors" >}}).
+
+## Abbreviations
+
+Stylized implementation of HTML's `<abbr>` element for abbreviations and acronyms to show the expanded version on hover. Abbreviations have a default underline and gain a help cursor to provide additional context on hover and to users of assistive technologies.
+
+Add `.initialism` to an abbreviation for a slightly smaller font-size.
+
+{{< example >}}
+<p><abbr title="attribute">attr</abbr></p>
+<p><abbr title="HyperText Markup Language" class="initialism">HTML</abbr></p>
+{{< /example >}}
+
+## Blockquotes
+
+For quoting blocks of content from another source within your document. Wrap `<blockquote class="blockquote">` around any <abbr title="HyperText Markup Language">HTML</abbr> as the quote.
+
+{{< example >}}
+<blockquote class="blockquote">
+  <p class="mb-0">A well-known quote, contained in a blockquote element.</p>
+</blockquote>
+{{< /example >}}
+
+### Naming a source
+
+Add a `<footer class="blockquote-footer">` for identifying the source. Wrap the name of the source work in `<cite>`.
+
+{{< example >}}
+<blockquote class="blockquote">
+  <p class="mb-0">A well-known quote, contained in a blockquote element.</p>
+  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
+</blockquote>
+{{< /example >}}
+
+### Alignment
+
+Use text utilities as needed to change the alignment of your blockquote.
+
+{{< example >}}
+<blockquote class="blockquote text-center">
+  <p class="mb-0">>A well-known quote, contained in a blockquote element.</p>
+  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
+</blockquote>
+{{< /example >}}
+
+{{< example >}}
+<blockquote class="blockquote text-right">
+  <p class="mb-0">A well-known quote, contained in a blockquote element.</p>
+  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
+</blockquote>
+{{< /example >}}
+
+## Lists
+
+### Unstyled
+
+Remove the default `list-style` and left margin on list items (immediate children only). **This only applies to immediate children list items**, meaning you will need to add the class for any nested lists as well.
+
+{{< example >}}
+<ul class="list-unstyled">
+  <li>This is a list.</li>
+  <li>It appears completely unstyled.</li>
+  <li>Structurally, it's still a list.</li>
+  <li>However, this style only applies to immediate child elements.</li>
+  <li>Nested lists:
+    <ul>
+      <li>are unaffected by this style</li>
+      <li>will still show a bullet</li>
+      <li>and have appropriate left margin</li>
+    </ul>
+  </li>
+  <li>This may still come in handy in some situations.</li>
+</ul>
+{{< /example >}}
+
+### Inline
+
+Remove a list's bullets and apply some light `margin` with a combination of two classes, `.list-inline` and `.list-inline-item`.
+
+{{< example >}}
+<ul class="list-inline">
+  <li class="list-inline-item">This is a list item.</li>
+  <li class="list-inline-item">And another one.</li>
+  <li class="list-inline-item">But they're displayed inline.</li>
+</ul>
+{{< /example >}}
+
+### Description list alignment
+
+Align terms and descriptions horizontally by using our grid system's predefined classes (or semantic mixins). For longer terms, you can optionally add a `.text-truncate` class to truncate the text with an ellipsis.
+
+{{< example >}}
+<dl class="row">
+  <dt class="col-sm-3">Description lists</dt>
+  <dd class="col-sm-9">A description list is perfect for defining terms.</dd>
+
+  <dt class="col-sm-3">Term</dt>
+  <dd class="col-sm-9">
+    <p>Definition for the term.</p>
+    <p>And some more placeholder definition text.</p>
+  </dd>
+
+  <dt class="col-sm-3">Another term</dt>
+  <dd class="col-sm-9">This definition is short, so no extra paragraphs or anything.</dd>
+
+  <dt class="col-sm-3 text-truncate">Truncated term is truncated</dt>
+  <dd class="col-sm-9">This can be useful when space is tight. Adds an ellipsis at the end.</dd>
+
+  <dt class="col-sm-3">Nesting</dt>
+  <dd class="col-sm-9">
+    <dl class="row">
+      <dt class="col-sm-4">Nested definition list</dt>
+      <dd class="col-sm-8">I heard you like definition lists. Let me put a definition list inside your definition list.</dd>
+    </dl>
+  </dd>
+</dl>
+{{< /example >}}
+
+## Responsive font sizes
+
+As of v4.3.0, Bootstrap ships with the option to enable responsive font sizes, allowing text to scale more naturally across device and viewport sizes. <abbr title="Responsive font sizes">RFS</abbr> can be enabled by changing the `$enable-responsive-font-sizes` Sass variable to `true` and recompiling Bootstrap.
+
+To support <abbr title="Responsive font sizes">RFS</abbr>, we use a Sass mixin to replace our normal `font-size` properties. Responsive font sizes will be compiled into `calc()` functions with a mix of `rem` and viewport units to enable the responsive scaling behavior. More about <abbr title="Responsive font sizes">RFS</abbr> and its configuration can be found on its [GitHub repository](https://github.com/twbs/rfs/tree/v8.0.4).

+  <p>Per the documentation, nesting is easy—just put a row of columns within an existing column. This gives you two columns <strong>starting at desktops and scaling to large desktops</strong>, with another two (equal widths) within the larger column.</p>
+  <p>At mobile device sizes, tablets and down, these columns and their nested columns will stack.</p>

+  <p>The Bootstrap v4 grid system has five tiers of classes: xs (extra small, this class infix is not used), sm (small), md (medium), lg (large), and xl (extra large). You can use nearly any combination of these classes to create more dynamic and flexible layouts.</p>
+  <p>Each tier of classes scales up, meaning if you plan on setting the same widths for md, lg and xl, you only need to specify md.</p>

For positioning of navbars, checkout the <a href="{{< docsref "/examples/navbar-static" >}}">top</a> and <a href="{{< docsref "/examples/navbar-fixed" >}}">fixed top</a> examples.</p>
+        <p>At the smallest breakpoint, the collapse plugin is used to hide the links and show a menu button to toggle the collapsed content.</p>

+title: Accessibility
+description: A brief overview of Bootstrap's features and limitations for the creation of accessible content.
+group: getting-started
+toc: true
+---
+
+Bootstrap provides an easy-to-use framework of ready-made styles, layout tools, and interactive components, allowing developers to create websites and applications that are visually appealing, functionally rich, and accessible out of the box.
+
+## Overview and Limitations
+
+The overall accessibility of any project built with Bootstrap depends in large part on the author's markup, additional styling, and scripting they've included. However, provided that these have been implemented correctly, it should be perfectly possible to create websites and applications with Bootstrap that fulfill [<abbr title="Web Content Accessibility Guidelines">WCAG</abbr> 2.0](https://www.w3.org/TR/WCAG20/) (A/AA/AAA), [Section 508](https://www.section508.gov/) and similar accessibility standards and requirements.
+
+### Structural markup
+
+Bootstrap's styling and layout can be applied to a wide range of markup structures. This documentation aims to provide developers with best practice examples to demonstrate the use of Bootstrap itself and illustrate appropriate semantic markup, including ways in which potential accessibility concerns can be addressed.
+
+### Interactive components
+
+Bootstrap's interactive components—such as modal dialogs, dropdown menus and custom tooltips—are designed to work for touch, mouse and keyboard users. Through the use of relevant [<abbr title="Web Accessibility Initiative">WAI</abbr>-<abbr title="Accessible Rich Internet Applications">ARIA</abbr>](https://www.w3.org/WAI/standards-guidelines/aria/) roles and attributes, these components should also be understandable and operable using assistive technologies (such as screen readers).
+
+Because Bootstrap's components are purposely designed to be fairly generic, authors may need to include further <abbr title="Accessible Rich Internet Applications">ARIA</abbr> roles and attributes, as well as JavaScript behavior, to more accurately convey the precise nature and functionality of their component. This is usually noted in the documentation.
+
+### Color contrast
+
+Most colors that currently make up Bootstrap's default palette—used throughout the framework for things such as button variations, alert variations, form validation indicators—lead to *insufficient* color contrast (below the recommended [WCAG 2.0 color contrast ratio of 4.5:1](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html)) when used against a light background. Authors will need to manually modify/extend these default colors to ensure adequate color contrast ratios.
+
+### Visually hidden content
+
+Content which should be visually hidden, but remain accessible to assistive technologies such as screen readers, can be styled using the `.sr-only` class. This can be useful in situations where additional visual information or cues (such as meaning denoted through the use of color) need to also be conveyed to non-visual users.
+
+```html
+<p class="text-danger">
+  <span class="sr-only">Danger: </span>
+  This action is not reversible
+</p>
+```
+
+For visually hidden interactive controls, such as traditional "skip" links, `.sr-only` can be combined with the `.sr-only-focusable` class. This will ensure that the control becomes visible once focused (for sighted keyboard users).
+
+```html
+<a class="sr-only sr-only-focusable" href="#content">Skip to main content</a>
+```
+
+### Reduced motion
+
+Bootstrap includes support for the [`prefers-reduced-motion` media feature](https://drafts.csswg.org/mediaqueries-5/#prefers-reduced-motion). In browsers/environments that allow the user to specify their preference for reduced motion, most CSS transition effects in Bootstrap (for instance, when a modal dialog is opened or closed, or the sliding animation in carousels) will be disabled, and meaningful animations (such as spinners) will be slowed down.

+title: Browsers and devices
+description: Learn about the browsers and devices, from modern to old, that are supported by Bootstrap, including known quirks and bugs for each.
+group: getting-started
+toc: true
+---
+
+## Supported browsers
+
+Bootstrap supports the **latest, stable releases** of all major browsers and platforms. On Windows, **we support Internet Explorer 10-11 / Microsoft Edge**.
+
+Alternative browsers which use the latest version of WebKit, Blink, or Gecko, whether directly or via the platform's web view API, are not explicitly supported. However, Bootstrap should (in most cases) display and function correctly in these browsers as well. More specific support information is provided below.
+
+You can find our supported range of browsers and their versions [in our `.browserslistrc file`]({{< param repo >}}/blob/v{{< param current_version >}}/.browserslistrc):
+
+```text
+{{< rf.inline >}}
+{{- readFile ".browserslistrc" | chomp | htmlEscape -}}
+{{< /rf.inline >}}
+```
+
+We use [Autoprefixer](https://github.com/postcss/autoprefixer) to handle intended browser support via CSS prefixes, which uses [Browserslist](https://github.com/browserslist/browserslist) to manage these browser versions. Consult their documentation for how to integrate these tools into your projects.
+
+### Mobile devices
+
+Generally speaking, Bootstrap supports the latest versions of each major platform's default browsers. Note that proxy browsers (such as Opera Mini, Opera Mobile's Turbo mode, UC Browser Mini, Amazon Silk) are not supported.

+      <td class="text-success">Supported</td>
+      <td class="text-danger">Not supported</td>
+    </tr>
+  </tbody>
+</table>
+
+For Firefox, in addition to the latest normal stable release, we also support the latest [Extended Support Release (ESR)](https://www.mozilla.org/en-US/firefox/enterprise/) version of Firefox.
+
+Unofficially, Bootstrap should look and behave well enough in Chromium and Chrome for Linux, Firefox for Linux, and Internet Explorer 9, though they are not officially supported.
+
+For a list of some of the browser bugs that Bootstrap has to grapple with, see our [Wall of browser bugs]({{< docsref "/browser-bugs" >}}).
+
+## Internet Explorer
+
+Internet Explorer 10+ is supported; IE9 and down is not. Please be aware that some CSS3 properties and HTML5 elements are not fully supported in IE10, or require prefixed properties for full functionality. Visit [Can I use...](https://caniuse.com/) for details on browser support of CSS3 and HTML5 features. **If you require IE8-9 support, use Bootstrap 3.**
+
+## Modals and dropdowns on mobile
+
+### Overflow and scrolling
+
+Support for `overflow: hidden;` on the `<body>` element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices' browsers, the `<body>` content will begin to scroll. See [Chrome bug #175502](https://bugs.chromium.org/p/chromium/issues/detail?id=175502) (fixed in Chrome v40) and [WebKit bug #153852](https://bugs.webkit.org/show_bug.cgi?id=153852).
+
+### iOS text fields and scrolling
+
+As of iOS 9.2, while a modal is open, if the initial touch of a scroll gesture is within the boundary of a textual `<input>` or a `<textarea>`, the `<body>` content underneath the modal will be scrolled instead of the modal itself. See [WebKit bug #153856](https://bugs.webkit.org/show_bug.cgi?id=153856).
+
+### Navbar Dropdowns
+
+The `.dropdown-backdrop` element isn't used on iOS in the nav because of the complexity of z-indexing. Thus, to close dropdowns in navbars, you must directly click the dropdown element (or [any other element which will fire a click event in iOS](https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event#Safari_Mobile)).
+
+## Browser zooming
+
+Page zooming inevitably presents rendering artifacts in some components, both in Bootstrap and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.
+
+## Sticky `:hover`/`:focus` on iOS
+
+While `:hover` isn't possible on most touch devices, iOS emulates this behavior, resulting in "sticky" hover styles that persist after tapping one element. These hover styles are only removed when users tap another element. This behavior is considered largely undesirable and appears to not be an issue on Android or Windows devices.
+
+Throughout our v4 alpha and beta releases, we included incomplete and commented out code for opting into a media query shim that would disable hover styles in touch device browsers that emulate hovering. This work was never fully completed or enabled, but to avoid complete breakage, we've opted to deprecate [this shim](https://github.com/twbs/mq4-hover-shim) and keep the mixins as shortcuts for the pseudo-classes.
+
+## Printing
+
+Even in some modern browsers, printing can be quirky.
+
+As of Safari v8.0, use of the fixed-width `.container` class can cause Safari to use an unusually small font size when printing. See [issue #14868]({{< param repo >}}/issues/14868) and [WebKit bug #138192](https://bugs.webkit.org/show_bug.cgi?id=138192) for more details. One potential workaround is the following CSS:
+
+```css
+@media print {
+  .container {
+    width: auto;
+  }
+}
+```
+
+## Android stock browser
+
+Out of the box, Android 4.1 (and even some newer releases apparently) ship with the Browser app as the default web browser of choice (as opposed to Chrome). Unfortunately, the Browser app has lots of bugs and inconsistencies with CSS in general.
+
+### Select menu
+
+On `<select>` elements, the Android stock browser will not display the side controls if there is a `border-radius` and/or `border` applied. (See [this StackOverflow question](https://stackoverflow.com/questions/14744437/html-select-box-not-showing-drop-down-arrow-on-android-version-4-0-when-set-with) for details.) Use the snippet of code below to remove the offending CSS and render the `<select>` as an unstyled element on the Android stock browser. The user agent sniffing avoids interference with Chrome, Safari, and Mozilla browsers.
+
+```html
+<script>
+$(function () {
+  var nua = navigator.userAgent
+  var isAndroid = (nua.indexOf('Mozilla/5.0') > -1 && nua.indexOf('Android ') > -1 && nua.indexOf('AppleWebKit') > -1 && nua.indexOf('Chrome') === -1)
+  if (isAndroid) {
+    $('select.form-control').removeClass('form-control').css('width', '100%')
+  }
+})
+</script>
+```
+
+Want to see an example? [Check out this JS Bin demo](http://jsbin.com/OyaqoDO/2).
+
+## Validators
+
+In order to provide the best possible experience to old and buggy browsers, Bootstrap uses [CSS browser hacks](http://browserhacks.com/) in several places to target special CSS to certain browser versions in order to work around bugs in the browsers themselves. These hacks understandably cause CSS validators to complain that they are invalid. In a couple places, we also use bleeding-edge CSS features that aren't yet fully standardized, but these are used purely for progressive enhancement.
+
+These validation warnings don't matter in practice since the non-hacky portion of our CSS does fully validate and the hacky portions don't interfere with the proper functioning of the non-hacky portion, hence why we deliberately ignore these particular warnings.
+
+Our HTML docs likewise have some trivial and inconsequential HTML validation warnings due to our inclusion of a workaround for [a certain Firefox bug](https://bugzilla.mozilla.org/show_bug.cgi?id=654072).

+title: Build tools
+description: Learn how to use Bootstrap's included npm scripts to build our documentation, compile source code, run tests, and more.
+group: getting-started
+toc: true
+---
+
+## Tooling setup
+
+Bootstrap uses [npm scripts](https://docs.npmjs.com/misc/scripts/) for its build system. Our [package.json]({{< param repo >}}/blob/v{{< param current_version >}}/package.json) includes convenient methods for working with the framework, including compiling code, running tests, and more.
+
+To use our build system and run our documentation locally, you'll need a copy of Bootstrap's source files and Node. Follow these steps and you should be ready to rock:
+
+1. [Download and install Node.js](https://nodejs.org/en/download/), which we use to manage our dependencies.
+2. Either [download Bootstrap's sources]({{< param "download.source" >}}) or fork [Bootstrap's repository]({{< param repo >}}).
+3. Navigate to the root `/bootstrap` directory and run `npm install` to install our local dependencies listed in [package.json]({{< param repo >}}/blob/v{{< param current_version >}}/package.json).
+
+When completed, you'll be able to run the various commands provided from the command line.
+
+## Using npm scripts
+
+Our [package.json]({{< param repo >}}/blob/v{{< param current_version >}}/package.json) includes the following commands and tasks:
+
+| Task | Description |
+| --- | --- |
+| `npm run dist` | `npm run dist` creates the `/dist/` directory with compiled files. **Uses [Sass](https://sass-lang.com/), [Autoprefixer][autoprefixer], and [terser](https://github.com/terser/terser).** |
+| `npm test` | Runs tests locally after running `npm run dist` |
+| `npm run docs-serve` | Builds and runs the documentation locally. |
+
+Run `npm run` to see all the npm scripts.
+
+{{< callout info >}}
+{{< partial "callout-info-npm-starter.md" >}}
+{{< /callout >}}
+
+## Sass
+
+Bootstrap v4 uses [Node Sass](https://github.com/sass/node-sass) for compiling our Sass source files into CSS files (included in our build process). In order to end up with the same generated CSS when compiling Sass using your own asset pipeline, you'll need to use a Sass compiler that supports at least the features that Node Sass does. This is important to note because as of October 26, 2020, LibSass and packages built on top of it—including Node Sass—are [deprecated](https://sass-lang.com/blog/libsass-is-deprecated).
+
+If you require newer Sass features or compatibility with newer CSS standards, [Dart Sass](https://sass-lang.com/dart-sass) is now the primary implementation of Sass and supports a JavaScript API that's fully compatible with Node Sass (with a few exceptions listed on Dart Sass's [GitHub page](https://github.com/sass/dart-sass)).
+
+We increase the Sass rounding precision to 6 (by default, it's 5 in Node Sass) to prevent issues with browser rounding. If you use Dart Sass this won't be something you need to adjust, as that compiler uses a rounding precision of 10 and for efficiency reasons does not allow it to be adjusted.
+
+## Autoprefixer
+
+Bootstrap uses [Autoprefixer][autoprefixer] (included in our build process) to automatically add vendor prefixes to some CSS properties at build time. Doing so saves us time and code by allowing us to write key parts of our CSS a single time while eliminating the need for vendor mixins like those found in v3.
+
+We maintain the list of browsers supported through Autoprefixer in a separate file within our GitHub repository. See [.browserslistrc]({{< param repo >}}/blob/v{{< param current_version >}}/.browserslistrc) for details.
+
+## Local documentation
+
+Running our documentation locally requires the use of Hugo, which gets installed via the [hugo-bin](https://www.npmjs.com/package/hugo-bin) npm package. Hugo is a blazingly fast and quite extensible static site generator that provides us: basic includes, Markdown-based files, templates, and more. Here's how to get it started:
+
+1. Run through the [tooling setup](#tooling-setup) above to install all dependencies.
+2. From the root `/bootstrap` directory, run `npm run docs-serve` in the command line.
+3. Open `http://localhost:9001/` in your browser, and voilà.
+
+Learn more about using Hugo by reading its [documentation](https://gohugo.io/documentation/).
+
+## Troubleshooting
+
+Should you encounter problems with installing dependencies, uninstall all previous dependency versions (global and local). Then, rerun `npm install`.

+```
+
+This is the most basic form of Bootstrap: precompiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (`bootstrap.*`), as well as compiled and minified CSS and JS (`bootstrap.min.*`). [source maps](https://developers.google.com/web/tools/chrome-devtools/javascript/source-maps) (`bootstrap.*.map`) are available for use with certain browsers' developer tools. Bundled JS files (`bootstrap.bundle.js` and minified `bootstrap.bundle.min.js`) include [Popper](https://popper.js.org/), but not [jQuery](https://jquery.com/).
+
+## CSS files
+
+Bootstrap includes a handful of options for including some or all of our compiled CSS.
+
+<table class="table table-bordered">

+      <td class="bg-light text-muted">Not included</td>
+    </tr>
+  </tbody>
+</table>
+
+## JS files
+
+Similarly, we have options for including some or all of our compiled JavaScript.
+
+<table class="table table-bordered">
+  <thead>
+    <tr>
+      <th scope="col">JS files</th>
+      <th scope="col">Popper</th>
+      <th scope="col">jQuery</th>

+      <td class="bg-light text-muted">Not included</td>
+      <td class="bg-light text-muted">Not included</td>
+    </tr>
+  </tbody>
+</table>
+
+## Bootstrap source code
+
+The Bootstrap source code download includes the precompiled CSS and JavaScript assets, along with source Sass, JavaScript, and documentation. More specifically, it includes the following and more:
+
+```text
+bootstrap/
+├── dist/
+│   ├── css/
+│   └── js/
+├── site/
+│   └──content/
+|      └──docs/
+|         └── 4.6/
+|             └── examples/
+├── js/
+└── scss/
+```
+
+The `scss/` and `js/` are the source code for our CSS and JavaScript. The `dist/` folder includes everything listed in the precompiled download section above. The `site/docs/` folder includes the source code for our documentation, and `examples/` of Bootstrap usage. Beyond that, any other included file provides support for packages, license information, and development.

+
+## Compiled CSS and JS
+
+Download ready-to-use compiled code for **Bootstrap v{{< param current_version >}}** to easily drop into your project, which includes:
+
+- Compiled and minified CSS bundles (see [CSS files comparison]({{< docsref "/getting-started/contents#css-files" >}}))
+- Compiled and minified JavaScript plugins (see [JS files comparison]({{< docsref "/getting-started/contents#js-files" >}}))
+
+This doesn't include documentation, source files, or any optional JavaScript dependencies (jQuery and Popper).
+
+<a href="{{< param "download.dist" >}}" class="btn btn-bd-primary" onclick="ga('send', 'event', 'Getting started', 'Download', 'Download Bootstrap');">Download</a>
+
+## Source files
+
+Compile Bootstrap with your own asset pipeline by downloading our source Sass, JavaScript, and documentation files. This option requires some additional tooling:
+
+- [Sass compiler]({{< docsref "/getting-started/build-tools#sass" >}}) for compiling Sass source files into CSS files
+- [Autoprefixer](https://github.com/postcss/autoprefixer) for CSS vendor prefixing
+
+Should you require our full set of [build tools]({{< docsref "/getting-started/build-tools#tooling-setup" >}}), they are included for developing Bootstrap and its docs, but they're likely unsuitable for your own purposes.
+
+<a href="{{< param "download.source" >}}" class="btn btn-bd-primary" onclick="ga('send', 'event', 'Getting started', 'Download', 'Download source');">Download source</a>
+
+## Examples
+
+If you want to download and examine our [examples]({{< docsref "/examples" >}}), you can grab the already built examples:
+
+<a href="{{< param "download.dist_examples" >}}" class="btn btn-bd-primary" onclick="ga('send', 'event', 'Getting started', 'Download', 'Download Examples');">Download Examples</a>
+
+## jsDelivr
+
+Skip the download with [jsDelivr](https://www.jsdelivr.com/) to deliver cached version of Bootstrap's compiled CSS and JS to your project.
+
+```html
+<link rel="stylesheet" href="{{< param "cdn.css" >}}" integrity="{{< param "cdn.css_hash" >}}" crossorigin="anonymous">
+<script src="{{< param "cdn.js_bundle" >}}" integrity="{{< param "cdn.js_bundle_hash" >}}" crossorigin="anonymous"></script>
+```
+
+If you're using our compiled JavaScript and prefer to include Popper separately, add Popper before our JS, via a CDN preferably.
+
+```html
+<script src="{{< param "cdn.jquery" >}}" integrity="{{< param "cdn.jquery_hash" >}}" crossorigin="anonymous"></script>
+<script src="{{< param "cdn.popper" >}}" integrity="{{< param "cdn.popper_hash" >}}" crossorigin="anonymous"></script>
+<script src="{{< param "cdn.js" >}}" integrity="{{< param "cdn.js_hash" >}}" crossorigin="anonymous"></script>
+```
+
+## Package managers
+
+Pull in Bootstrap's **source files** into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will **require a [Sass compiler]({{< docsref "/getting-started/build-tools#sass" >}}) and [Autoprefixer](https://github.com/postcss/autoprefixer)** for a setup that matches our official compiled versions.
+
+### npm
+
+Install Bootstrap in your Node.js powered apps with [the npm package](https://www.npmjs.com/package/bootstrap):
+
+```sh
+npm install bootstrap
+```
+
+`require('bootstrap')` will load all of Bootstrap's jQuery plugins onto the jQuery object. The `bootstrap` module itself does not export anything. You can manually load Bootstrap's jQuery plugins individually by loading the `/js/*.js` files under the package's top-level directory.
+
+Bootstrap's `package.json` contains some additional metadata under the following keys:
+
+- `sass` - path to Bootstrap's main [Sass](https://sass-lang.com/) source file
+- `style` - path to Bootstrap's non-minified CSS that's been precompiled using the default settings (no customization)
+
+{{< callout info >}}
+{{< partial "callout-info-npm-starter.md" >}}
+{{< /callout >}}
+
+### yarn
+
+Install Bootstrap in your Node.js powered apps with [the yarn package](https://yarnpkg.com/en/package/bootstrap):
+
+```sh
+yarn add bootstrap
+```
+
+### RubyGems
+
+Install Bootstrap in your Ruby apps using [Bundler](https://bundler.io/) (**recommended**) and [RubyGems](https://rubygems.org/) by adding the following line to your [`Gemfile`](https://bundler.io/gemfile.html):
+
+```ruby
+gem 'bootstrap', '~> {{< param current_ruby_version >}}'
+```
+
+Alternatively, if you're not using Bundler, you can install the gem by running this command:
+
+```sh
+gem install bootstrap -v {{< param current_ruby_version >}}
+```
+
+[See the gem's README](https://github.com/twbs/bootstrap-rubygem/blob/master/README.md) for further details.
+
+### Composer
+
+You can also install and manage Bootstrap's Sass and JavaScript using [Composer](https://getcomposer.org/):
+
+```sh
+composer require twbs/bootstrap:{{< param current_version >}}
+```
+
+### NuGet
+
+If you develop in .NET, you can also install and manage Bootstrap's [CSS](https://www.nuget.org/packages/bootstrap/) or [Sass](https://www.nuget.org/packages/bootstrap.sass/) and JavaScript using [NuGet](https://www.nuget.org/):
+
+```powershell
+Install-Package bootstrap
+```
+
+```powershell
+Install-Package bootstrap.sass
+```

+group: getting-started

+  - "/docs/4.6/getting-started/"
+  - "/docs/getting-started/"
+  - "/getting-started/"
+toc: true
+---
+
+## Quick start
+
+Looking to quickly add Bootstrap to your project? Use jsDelivr, a free open source CDN. Using a package manager or need to download the source files? [Head to the downloads page]({{< docsref "/getting-started/download" >}}).
+
+### CSS
+
+Copy-paste the stylesheet `<link>` into your `<head>` before all other stylesheets to load our CSS.
+
+```html
+<link rel="stylesheet" href="{{< param "cdn.css" >}}" integrity="{{< param "cdn.css_hash" >}}" crossorigin="anonymous">
+```
+
+### JS
+
+Many of our components require the use of JavaScript to function. Specifically, they require [jQuery](https://jquery.com/), [Popper](https://popper.js.org/), and our own JavaScript plugins. We use [jQuery's slim build](https://blog.jquery.com/2016/06/09/jquery-3-0-final-released/), but the full version is also supported.
+
+Place **one of the following `<script>`s** near the end of your pages, right before the closing `</body>` tag, to enable them. jQuery must come first, then Popper, and then our JavaScript plugins.
+
+#### Bundle
+
+Include every Bootstrap JavaScript plugin with one of our two bundles. Both `bootstrap.bundle.js` and `bootstrap.bundle.min.js` include [Popper](https://popper.js.org/) for our tooltips and popovers, but not [jQuery](https://jquery.com/). Include jQuery first, then a Bootstrap JavaScript bundle. For more information about what's included in Bootstrap, please see our [contents]({{< docsref "/getting-started/contents#precompiled-bootstrap" >}}) section.
+
+```html
+<script src="{{< param "cdn.jquery" >}}" integrity="{{< param "cdn.jquery_hash" >}}" crossorigin="anonymous"></script>
+<script src="{{< param "cdn.js_bundle" >}}" integrity="{{< param "cdn.js_bundle_hash" >}}" crossorigin="anonymous"></script>
+```
+
+#### Separate
+
+If you decide to go with the separate scripts solution, Popper must come first (if you're using tooltips or popovers), and then our JavaScript plugins.
+
+```html
+<script src="{{< param "cdn.jquery" >}}" integrity="{{< param "cdn.jquery_hash" >}}" crossorigin="anonymous"></script>
+<script src="{{< param "cdn.popper" >}}" integrity="{{< param "cdn.popper_hash" >}}" crossorigin="anonymous"></script>
+<script src="{{< param "cdn.js" >}}" integrity="{{< param "cdn.js_hash" >}}" crossorigin="anonymous"></script>
+```
+
+#### Components
+
+Curious which components explicitly require jQuery, our JavaScript, and Popper? Click the show components link below. If you're unsure about the page structure, keep reading for an example page template.
+
+<details>
+<summary class="text-primary mb-3">Show components requiring JavaScript</summary>
+{{< markdown >}}
+- Alerts for dismissing
+- Buttons for toggling states and checkbox/radio functionality
+- Carousel for all slide behaviors, controls, and indicators
+- Collapse for toggling visibility of content
+- Dropdowns for displaying and positioning (also requires [Popper](https://popper.js.org/))
+- Modals for displaying, positioning, and scroll behavior
+- Navbar for extending our Collapse plugin to implement responsive behavior
+- Tooltips and popovers for displaying and positioning (also requires [Popper](https://popper.js.org/))
+- Scrollspy for scroll behavior and navigation updates
+{{< /markdown >}}
+</details>
+
+## Starter template
+
+Be sure to have your pages set up with the latest design and development standards. That means using an HTML5 doctype and including a viewport meta tag for proper responsive behaviors. Put it all together and your pages should look like this:
+
+```html
+<!doctype html>
+<html lang="en">
+  <head>
+    <!-- Required meta tags -->
+    <meta charset="utf-8">
+    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
+
+    <!-- Bootstrap CSS -->
+    <link rel="stylesheet" href="{{< param "cdn.css" >}}" integrity="{{< param "cdn.css_hash" >}}" crossorigin="anonymous">
+
+    <title>Hello, world!</title>
+  </head>
+  <body>
+    <h1>Hello, world!</h1>
+
+    <!-- Optional JavaScript; choose one of the two! -->
+
+    <!-- Option 1: jQuery and Bootstrap Bundle (includes Popper) -->
+    <script src="{{< param "cdn.jquery" >}}" integrity="{{< param "cdn.jquery_hash" >}}" crossorigin="anonymous"></script>
+    <script src="{{< param "cdn.js_bundle" >}}" integrity="{{< param "cdn.js_bundle_hash" >}}" crossorigin="anonymous"></script>
+
+    <!-- Option 2: Separate Popper and Bootstrap JS -->
+    <!--
+    <script src="{{< param "cdn.jquery" >}}" integrity="{{< param "cdn.jquery_hash" >}}" crossorigin="anonymous"></script>
+    <script src="{{< param "cdn.popper" >}}" integrity="{{< param "cdn.popper_hash" >}}" crossorigin="anonymous"></script>
+    <script src="{{< param "cdn.js" >}}" integrity="{{< param "cdn.js_hash" >}}" crossorigin="anonymous"></script>
+    -->
+  </body>
+</html>

+
+## Important globals
+
+Bootstrap employs a handful of important global styles and settings that you'll need to be aware of when using it, all of which are almost exclusively geared towards the *normalization* of cross browser styles. Let's dive in.
+
+### HTML5 doctype
+
+Bootstrap requires the use of the HTML5 doctype. Without it, you'll see some funky incomplete styling, but including it shouldn't cause any considerable hiccups.
+
+```html
+<!doctype html>
+<html lang="en">
+  ...
+</html>
+```
+
+### Responsive meta tag
+
+Bootstrap is developed *mobile first*, a strategy in which we optimize code for mobile devices first and then scale up components as necessary using CSS media queries. To ensure proper rendering and touch zooming for all devices, **add the responsive viewport meta tag** to your `<head>`.
+
+```html
+<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
+```
+
+You can see an example of this in action in the [starter template](#starter-template).
+
+### Box-sizing
+
+For more straightforward sizing in CSS, we switch the global `box-sizing` value from `content-box` to `border-box`. This ensures `padding` does not affect the final computed width of an element, but it can cause problems with some third party software like Google Maps and Google Custom Search Engine.
+
+On the rare occasion you need to override it, use something like the following:
+
+```css
+.selector-for-some-widget {
+  box-sizing: content-box;
+}
+```
+
+With the above snippet, nested elements—including generated content via `::before` and `::after`—will all inherit the specified `box-sizing` for that `.selector-for-some-widget`.
+
+Learn more about [box model and sizing at CSS Tricks](https://css-tricks.com/box-sizing/).
+
+### Reboot
+
+For improved cross-browser rendering, we use [Reboot]({{< docsref "/content/reboot" >}}) to correct inconsistencies across browsers and devices while providing slightly more opinionated resets to common HTML elements.

+
+## CSPs and embedded SVGs
+
+Several Bootstrap components include embedded SVGs in our CSS to style components consistently and easily across browsers and devices. **For organizations with more strict <abbr title="Content Security Policy">CSP</abbr> configurations**, we've documented all instances of our embedded SVGs (all of which are applied via `background-image`) so you can more thoroughly review your options.

+
+Based on [community conversation](https://github.com/twbs/bootstrap/issues/25394), some options for addressing this in your own codebase include replacing the URLs with locally hosted assets, removing the images and using inline images (not possible in all components), and modifying your CSP. Our recommendation is to carefully review your own security policies and decide on a best path forward, if necessary.

+title: JavaScript
+description: Bring Bootstrap to life with our optional JavaScript plugins built on jQuery. Learn about each plugin, our data and programmatic API options, and more.
+group: getting-started
+toc: true
+---
+
+## Individual or compiled
+
+Plugins can be included individually (using Bootstrap's individual `js/dist/*.js`), or all at once using `bootstrap.js` or the minified `bootstrap.min.js` (don't include both).
+
+If you use a bundler (Webpack, Rollup...), you can use `/js/dist/*.js` files which are UMD ready.
+
+## Dependencies
+
+Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that **all plugins depend on jQuery** (this means jQuery must be included **before** the plugin files). [Consult our `package.json`]({{< param repo >}}/blob/v{{< param current_version >}}/package.json) to see which versions of jQuery are supported.
+
+Our dropdowns, popovers and tooltips also depend on [Popper.js](https://popper.js.org/).
+
+## Data attributes
+
+Nearly all Bootstrap plugins can be enabled and configured through HTML alone with data attributes (our preferred way of using JavaScript functionality). Be sure to **only use one set of data attributes on a single element** (e.g., you cannot trigger a tooltip and modal from the same button.)
+
+However, in some situations it may be desirable to disable this functionality. To disable the data attribute API, unbind all events on the document namespaced with `data-api` like so:
+
+```js
+$(document).off('.data-api')
+```
+
+Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:
+
+```js
+$(document).off('.alert.data-api')
+```
+
+{{< callout warning >}}
+## Selectors
+
+Currently to query DOM elements we use the native methods `querySelector` and `querySelectorAll` for performance reasons, so you have to use [valid selectors](https://www.w3.org/TR/CSS21/syndata.html#value-def-identifier).
+If you use special selectors, for example: `collapse:Example` be sure to escape them.
+{{< /callout >}}
+
+## Events
+
+Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. `show`) is triggered at the start of an event, and its past participle form (ex. `shown`) is triggered on the completion of an action.
+
+All infinitive events provide [`preventDefault()`](https://developer.mozilla.org/en-US/docs/Web/API/Event/preventDefault) functionality. This provides the ability to stop the execution of an action before it starts. Returning false from an event handler will also automatically call `preventDefault()`.
+
+```js
+$('#myModal').on('show.bs.modal', function (event) {
+  if (!data) {
+    return event.preventDefault() // stops modal from being shown
+  }
+})
+```
+
+## Programmatic API
+
+We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
+
+```js
+$('.btn.danger').button('toggle').addClass('fat')
+```
+
+All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
+
+```js
+$('#myModal').modal() // initialized with defaults
+$('#myModal').modal({ keyboard: false }) // initialized with no keyboard
+$('#myModal').modal('show') // initializes and invokes show immediately
+```
+
+Each plugin also exposes its raw constructor on a `Constructor` property: `$.fn.popover.Constructor`. If you'd like to get a particular plugin instance, retrieve it directly from an element: `$('[rel="popover"]').data('popover')`.
+
+### Asynchronous functions and transitions
+
+All programmatic API methods are **asynchronous** and return to the caller once the transition is started but **before it ends**.
+
+In order to execute an action once the transition is complete, you can listen to the corresponding event.
+
+```js
+$('#myCollapse').on('shown.bs.collapse', function (event) {
+  // Action to execute once the collapsible area is expanded
+})
+```
+
+In addition a method call on a **transitioning component will be ignored**.
+
+```js
+$('#myCarousel').on('slid.bs.carousel', function (event) {
+  $('#myCarousel').carousel('2') // Will slide to the slide 2 as soon as the transition to slide 1 is finished
+})
+
+$('#myCarousel').carousel('1') // Will start sliding to the slide 1 and returns to the caller
+$('#myCarousel').carousel('2') // !! Will be ignored, as the transition to the slide 1 is not finished !!
+```
+
+### Default settings
+
+You can change the default settings for a plugin by modifying the plugin's `Constructor.Default` object:
+
+```js
+// changes default for the modal plugin's `keyboard` option to false
+$.fn.modal.Constructor.Default.keyboard = false
+```
+
+## No conflict
+
+Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call `.noConflict` on the plugin you wish to revert the value of.
+
+```js
+var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
+$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality
+```
+
+## Version numbers
+
+The version of each of Bootstrap's jQuery plugins can be accessed via the `VERSION` property of the plugin's constructor. For example, for the tooltip plugin:
+
+```js
+$.fn.tooltip.Constructor.VERSION // => "{{< param current_version >}}"
+```
+
+## No special fallbacks when JavaScript is disabled
+
+Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user experience in this case, use [`<noscript>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/noscript) to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.
+
+{{< callout warning >}}
+##### Third-party libraries
+
+**Bootstrap does not officially support third-party JavaScript libraries** like Prototype or jQuery UI. Despite `.noConflict` and namespaced events, there may be compatibility problems that you need to fix on your own.
+{{< /callout >}}
+
+## Util
+
+All Bootstrap's JavaScript files depend on `util.js` and it has to be included alongside the other JavaScript files. If you're using the compiled (or minified) `bootstrap.js`, there is no need to include this—it's already there.
+
+`util.js` includes utility functions and a basic helper for `transitionEnd` events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.
+
+## Sanitizer
+
+Tooltips and Popovers use our built-in sanitizer to sanitize options which accept HTML.
+
+The default `whiteList` value is the following:
+
+```js
+var ARIA_ATTRIBUTE_PATTERN = /^aria-[\w-]*$/i
+var DefaultWhitelist = {
+  // Global attributes allowed on any supplied element below.
+  '*': ['class', 'dir', 'id', 'lang', 'role', ARIA_ATTRIBUTE_PATTERN],
+  a: ['target', 'href', 'title', 'rel'],
+  area: [],
+  b: [],
+  br: [],
+  col: [],
+  code: [],
+  div: [],
+  em: [],
+  hr: [],
+  h1: [],
+  h2: [],
+  h3: [],
+  h4: [],
+  h5: [],
+  h6: [],
+  i: [],
+  img: ['src', 'srcset', 'alt', 'title', 'width', 'height'],
+  li: [],
+  ol: [],
+  p: [],
+  pre: [],
+  s: [],
+  small: [],
+  span: [],
+  sub: [],
+  sup: [],
+  strong: [],
+  u: [],
+  ul: []
+}
+```
+
+If you want to add new values to this default `whiteList` you can do the following:
+
+```js
+var myDefaultWhiteList = $.fn.tooltip.Constructor.Default.whiteList
+
+// To allow table elements
+myDefaultWhiteList.table = []
+
+// To allow td elements and data-option attributes on td elements
+myDefaultWhiteList.td = ['data-option']
+
+// You can push your custom regex to validate your attributes.
+// Be careful about your regular expressions being too lax
+var myCustomRegex = /^data-my-app-[\w-]+/
+myDefaultWhiteList['*'].push(myCustomRegex)
+```
+
+If you want to bypass our sanitizer because you prefer to use a dedicated library, for example [DOMPurify](https://www.npmjs.com/package/dompurify), you should do the following:
+
+```js
+$('#yourTooltip').tooltip({
+  sanitizeFn: function (content) {
+    return DOMPurify.sanitize(content)
+  }
+})
+```

+title: Theming Bootstrap
+description: Customize Bootstrap 4 with our new built-in Sass variables for global style preferences for easy theming and component changes.
+group: getting-started
+toc: true
+---
+
+## Introduction
+
+In Bootstrap 3, theming was largely driven by variable overrides in LESS, custom CSS, and a separate theme stylesheet that we included in our `dist` files. With some effort, one could completely redesign the look of Bootstrap 3 without touching the core files. Bootstrap 4 provides a familiar, but slightly different approach.
+
+Now, theming is accomplished by Sass variables, Sass maps, and custom CSS. There's no more dedicated theme stylesheet; instead, you can enable the built-in theme to add gradients, shadows, and more.
+
+## Sass
+
+Utilize our source Sass files to take advantage of variables, maps, mixins, and more when [compiling Sass]({{< docsref "/getting-started/build-tools#sass" >}}) using your own asset pipeline.
+
+### File structure
+
+Whenever possible, avoid modifying Bootstrap's core files. For Sass, that means creating your own stylesheet that imports Bootstrap so you can modify and extend it. Assuming you're using a package manager like npm, you'll have a file structure that looks like this:
+
+```text
+your-project/
+├── scss
+│   └── custom.scss
+└── node_modules/
+    └── bootstrap
+        ├── js
+        └── scss
+```
+
+If you've downloaded our source files and aren't using a package manager, you'll want to manually setup something similar to that structure, keeping Bootstrap's source files separate from your own.
+
+```text
+your-project/
+├── scss
+│   └── custom.scss
+└── bootstrap/
+    ├── js
+    └── scss
+```
+
+### Importing
+
+In your `custom.scss`, you'll import Bootstrap's source Sass files. You have two options: include all of Bootstrap, or pick the parts you need. We encourage the latter, though be aware there are some requirements and dependencies across our components. You also will need to include some JavaScript for our plugins.
+
+```scss
+// Custom.scss
+// Option A: Include all of Bootstrap
+
+@import "../node_modules/bootstrap/scss/bootstrap";
+
+// Add custom code after this
+```
+
+```scss
+// Custom.scss
+// Option B: Include parts of Bootstrap
+
+// Required
+@import "../node_modules/bootstrap/scss/functions";
+@import "../node_modules/bootstrap/scss/variables";
+@import "../node_modules/bootstrap/scss/mixins";
+
+// Include custom variable default overrides here
+
+// Optional
+@import "../node_modules/bootstrap/scss/reboot";
+@import "../node_modules/bootstrap/scss/type";
+@import "../node_modules/bootstrap/scss/images";
+@import "../node_modules/bootstrap/scss/code";
+@import "../node_modules/bootstrap/scss/grid";
+```
+
+With that setup in place, you can begin to modify any of the Sass variables and maps in your `custom.scss`. You can also start to add parts of Bootstrap under the `// Optional` section as needed. We suggest using the full import stack from our `bootstrap.scss` file as your starting point.
+
+### Variable defaults
+
+Every Sass variable in Bootstrap includes the `!default` flag allowing you to override the variable's default value in your own Sass without modifying Bootstrap's source code. Copy and paste variables as needed, modify their values, and remove the `!default` flag. If a variable has already been assigned, then it won't be re-assigned by the default values in Bootstrap.
+
+You will find the complete list of Bootstrap's variables in `scss/_variables.scss`. Some variables are set to `null`, these variables don't output the property unless they are overridden in your configuration.
+
+Variable overrides must come after our functions, variables, and mixins are imported, but before the rest of the imports.
+
+Here's an example that changes the `background-color` and `color` for the `<body>` when importing and compiling Bootstrap via npm:
+
+```scss
+// Required
+@import "../node_modules/bootstrap/scss/functions";
+@import "../node_modules/bootstrap/scss/variables";
+@import "../node_modules/bootstrap/scss/mixins";
+
+// Your variable overrides
+$body-bg: #000;
+$body-color: #111;
+
+// Bootstrap and its default variables
+
+// Optional
+@import "../node_modules/bootstrap/scss/root";
+@import "../node_modules/bootstrap/scss/reboot";
+@import "../node_modules/bootstrap/scss/type";
+// etc
+```
+
+Repeat as necessary for any variable in Bootstrap, including the global options below.
+
+{{< callout info >}}
+{{< partial "callout-info-npm-starter.md" >}}
+{{< /callout >}}
+
+### Maps and loops
+
+Bootstrap 4 includes a handful of Sass maps, key value pairs that make it easier to generate families of related CSS. We use Sass maps for our colors, grid breakpoints, and more. Just like Sass variables, all Sass maps include the `!default` flag and can be overridden and extended.
+
+Some of our Sass maps are merged into empty ones by default. This is done to allow easy expansion of a given Sass map, but comes at the cost of making _removing_ items from a map slightly more difficult.
+
+#### Modify map
+
+To modify an existing color in our `$theme-colors` map, add the following to your custom Sass file:
+
+```scss
+$theme-colors: (
+  "primary": #0074d9,
+  "danger": #ff4136
+);
+```
+
+#### Add to map
+
+To add a new color to `$theme-colors`, add the new key and value:
+
+```scss
+$theme-colors: (
+  "custom-color": #900
+);
+```
+
+#### Remove from map
+
+To remove colors from `$theme-colors`, or any other map, use `map-remove`. Be aware you must insert it between our requirements and options:
+
+```scss
+// Required
+@import "../node_modules/bootstrap/scss/functions";
+@import "../node_modules/bootstrap/scss/variables";
+@import "../node_modules/bootstrap/scss/mixins";
+
+$theme-colors: map-remove($theme-colors, "info", "light", "dark");
+
+// Optional
+@import "../node_modules/bootstrap/scss/root";
+@import "../node_modules/bootstrap/scss/reboot";
+@import "../node_modules/bootstrap/scss/type";
+...
+```
+
+#### Required keys
+
+Bootstrap assumes the presence of some specific keys within Sass maps as we used and extend these ourselves. As you customize the included maps, you may encounter errors where a specific Sass map's key is being used.
+
+For example, we use the `primary`, `success`, and `danger` keys from `$theme-colors` for links, buttons, and form states. Replacing the values of these keys should present no issues, but removing them may cause Sass compilation issues. In these instances, you'll need to modify the Sass code that makes use of those values.
+
+### Functions
+
+Bootstrap utilizes several Sass functions, but only a subset are applicable to general theming. We've included three functions for getting values from the color maps:
+
+```scss
+@function color($key: "blue") {
+  @return map-get($colors, $key);
+}
+
+@function theme-color($key: "primary") {
+  @return map-get($theme-colors, $key);
+}
+
+@function gray($key: "100") {
+  @return map-get($grays, $key);
+}
+```
+
+These allow you to pick one color from a Sass map much like how you'd use a color variable from v3.
+
+```scss
+.custom-element {
+  color: gray("100");
+  background-color: theme-color("dark");
+}
+```
+
+We also have another function for getting a particular _level_ of color from the `$theme-colors` map. Negative level values will lighten the color, while higher levels will darken.
+
+```scss
+@function theme-color-level($color-name: "primary", $level: 0) {
+  $color: theme-color($color-name);
+  $color-base: if($level > 0, #000, #fff);
+  $level: abs($level);
+
+  @return mix($color-base, $color, $level * $theme-color-interval);
+}
+```
+
+In practice, you'd call the function and pass in two parameters: the name of the color from `$theme-colors` (e.g., primary or danger) and a numeric level.
+
+```scss
+.custom-element {
+  color: theme-color-level(primary, -10);
+}
+```
+
+Additional functions could be added in the future or your own custom Sass to create level functions for additional Sass maps, or even a generic one if you wanted to be more verbose.
+
+#### Color contrast
+
+An additional function we include in Bootstrap is the color contrast function, `color-yiq`. It utilizes the [YIQ color space](https://en.wikipedia.org/wiki/YIQ) to automatically return a light (`#fff`) or dark (`#111`) contrast color based on the specified base color. This function is especially useful for mixins or loops where you're generating multiple classes.
+
+For example, to generate color swatches from our `$theme-colors` map:
+
+```scss
+@each $color, $value in $theme-colors {
+  .swatch-#{$color} {
+    color: color-yiq($value);
+  }
+}
+```
+
+It can also be used for one-off contrast needs:
+
+```scss
+.custom-element {
+  color: color-yiq(#000); // returns `color: #fff`
+}
+```
+
+You can also specify a base color with our color map functions:
+
+```scss
+.custom-element {
+  color: color-yiq(theme-color("dark")); // returns `color: #fff`
+}
+```
+
+#### Escape SVG
+
+We use the `escape-svg` function to escape the `<`, `>` and `#` characters for SVG background images. These characters need to be escaped to properly render the background images in IE. When using the `escape-svg` function, data URIs must be quoted.
+
+#### Add and Subtract functions
+
+We use the `add` and `subtract` functions to wrap the CSS `calc` function. The primary purpose of these functions is to avoid errors when a "unitless" `0` value is passed into a `calc` expression. Expressions like `calc(10px - 0)` will return an error in all browsers, despite being mathematically correct.
+
+Example where the calc is valid:
+
+```scss
+$border-radius: .25rem;
+$border-width: 1px;
+
+.element {
+  // Output calc(.25rem - 1px) is valid
+  border-radius: calc($border-radius - $border-width);
+}
+
+.element {
+  // Output the same calc(.25rem - 1px) as above
+  border-radius: subtract($border-radius, $border-width);
+}
+```
+
+Example where the calc is invalid:
+
+```scss
+$border-radius: .25rem;
+$border-width: 0;
+
+.element {
+  // Output calc(.25rem - 0) is invalid
+  border-radius: calc($border-radius - $border-width);
+}
+
+.element {
+  // Output .25rem
+  border-radius: subtract($border-radius, $border-width);
+}
+```
+
+## Sass options
+
+Customize Bootstrap 4 with our built-in custom variables file and easily toggle global CSS preferences with new `$enable-*` Sass variables. Override a variable's value and recompile with `npm run test` as needed.
+
+You can find and customize these variables for key global options in Bootstrap's `scss/_variables.scss` file.
+
+| Variable                                     | Values                             | Description                                                                            |
+| -------------------------------------------- | ---------------------------------- | -------------------------------------------------------------------------------------- |
+| `$spacer`                                    | `1rem` (default), or any value > 0 | Specifies the default spacer value to programmatically generate our [spacer utilities]({{< docsref "/utilities/spacing" >}}). |
+| `$enable-rounded`                            | `true` (default) or `false`        | Enables predefined `border-radius` styles on various components. |
+| `$enable-shadows`                            | `true` or `false` (default)        | Enables predefined decorative `box-shadow` styles on various components. Does not affect `box-shadow`s used for focus states. |
+| `$enable-gradients`                          | `true` or `false` (default)        | Enables predefined gradients via `background-image` styles on various components. |
+| `$enable-transitions`                        | `true` (default) or `false`        | Enables predefined `transition`s on various components. |

+
+## Color
+
+Many of Bootstrap's various components and utilities are built through a series of colors defined in a Sass map. This map can be looped over in Sass to quickly generate a series of rulesets.
+
+### All colors
+
+All colors available in Bootstrap 4, are available as Sass variables and a Sass map in `scss/_variables.scss` file. This will be expanded upon in subsequent minor releases to add additional shades, much like the [grayscale palette](#grays) we already include.
+
+<div class="row">
+  {{< theme-colors.inline >}}
+  {{- range $.Site.Data.colors }}
+    {{- if (and (not (eq .name "white")) (not (eq .name "gray")) (not (eq .name "gray-dark"))) }}
+    <div class="col-md-4">
+      <div class="p-3 mb-3 text-monospace swatch-{{ .name }}">
+        <strong class="d-block">${{ .name }}</strong>
+        <small>{{ .hex }}</small>
+      </div>
+    </div>
+    {{ end -}}
+  {{ end -}}
+  {{< /theme-colors.inline >}}
+</div>
+
+Here's how you can use these in your Sass:
+
+```scss
+// With variable
+.alpha { color: $purple; }
+
+// From the Sass map with our `color()` function
+.beta { color: color("purple"); }
+```
+
+[Color utility classes]({{< docsref "/utilities/colors" >}}) are also available for setting `color` and `background-color`.
+
+{{< callout info >}}
+In the future, we'll aim to provide Sass maps and variables for shades of each color as we've done with the grayscale colors below.
+{{< /callout >}}
+
+### Theme colors
+
+We use a subset of all colors to create a smaller color palette for generating color schemes, also available as Sass variables and a Sass map in Bootstrap's `scss/_variables.scss` file.
+
+<div class="row">
+  {{< theme-colors.inline >}}
+  {{- range (index $.Site.Data "theme-colors") }}
+    <div class="col-md-4">
+      <div class="p-3 mb-3 text-monospace bg-{{ .name }} {{ if (or (eq .name "light") (eq .name "warning")) }}text-dark{{ else }}text-white{{ end }}">
+        <strong class="d-block">${{ .name }}</strong>
+        <small>{{ .hex }}</small>
+      </div>
+    </div>
+  {{ end -}}
+  {{< /theme-colors.inline >}}
+</div>
+
+### Grays
+
+An expansive set of gray variables and a Sass map in `scss/_variables.scss` for consistent shades of gray across your project. Note that these are "cool grays", which tend towards a subtle blue tone, rather than neutral grays.
+
+<div class="row mb-3">
+  <div class="col-md-4">
+    {{< theme-colors.inline >}}
+    {{- range $.Site.Data.grays }}
+      <div class="p-3 text-monospace swatch-{{ .name }}">
+        <strong class="d-block">$gray-{{ .name }}</strong>
+        <small>{{ .hex }}</small>
+      </div>
+    {{ end -}}
+  {{< /theme-colors.inline >}}
+  </div>
+</div>
+
+Within `scss/_variables.scss`, you'll find Bootstrap's color variables and Sass map. Here's an example of the `$colors` Sass map:
+
+```scss
+$colors: (
+  "blue": $blue,
+  "indigo": $indigo,
+  "purple": $purple,
+  "pink": $pink,
+  "red": $red,
+  "orange": $orange,
+  "yellow": $yellow,
+  "green": $green,
+  "teal": $teal,
+  "cyan": $cyan,
+  "white": $white,
+  "gray": $gray-600,
+  "gray-dark": $gray-800
+) !default;
+```
+
+Add, remove, or modify values within the map to update how they're used in many other components. Unfortunately at this time, not _every_ component utilizes this Sass map. Future updates will strive to improve upon this. Until then, plan on making use of the `${color}` variables and this Sass map.
+
+## Components
+
+Many of Bootstrap's components and utilities are built with `@each` loops that iterate over a Sass map. This is especially helpful for generating variants of a component by our `$theme-colors` and creating responsive variants for each breakpoint. As you customize these Sass maps and recompile, you'll automatically see your changes reflected in these loops.
+
+### Modifiers
+
+Many of Bootstrap's components are built with a base-modifier class approach. This means the bulk of the styling is contained to a base class (e.g., `.btn`) while style variations are confined to modifier classes (e.g., `.btn-danger`). These modifier classes are built from the `$theme-colors` map to make customizing the number and name of our modifier classes.
+
+Here are two examples of how we loop over the `$theme-colors` map to generate modifiers to the `.alert` component and all our `.bg-*` background utilities.
+
+```scss
+// Generate alert modifier classes
+@each $color, $value in $theme-colors {
+  .alert-#{$color} {
+    @include alert-variant(theme-color-level($color, -10), theme-color-level($color, -9), theme-color-level($color, 6));
+  }
+}
+
+// Generate `.bg-*` color utilities
+@each $color, $value in $theme-colors {
+  @include bg-variant('.bg-#{$color}', $value);
+}
+```
+
+### Responsive
+
+These Sass loops aren't limited to color maps, either. You can also generate responsive variations of your components or utilities. Take for example our responsive text alignment utilities where we mix an `@each` loop for the `$grid-breakpoints` Sass map with a media query include.
+
+```scss
+@each $breakpoint in map-keys($grid-breakpoints) {
+  @include media-breakpoint-up($breakpoint) {
+    $infix: breakpoint-infix($breakpoint, $grid-breakpoints);
+
+    .text#{$infix}-left   { text-align: left !important; }
+    .text#{$infix}-right  { text-align: right !important; }
+    .text#{$infix}-center { text-align: center !important; }
+  }
+}
+```
+
+Should you need to modify your `$grid-breakpoints`, your changes will apply to all the loops iterating over that map.
+
+## CSS variables
+
+Bootstrap 4 includes around two dozen [CSS custom properties (variables)](https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties) in its compiled CSS. These provide easy access to commonly used values like our theme colors, breakpoints, and primary font stacks when working in your browser's Inspector, a code sandbox, or general prototyping.
+
+### Available variables
+
+Here are the variables we include (note that the `:root` is required). They're located in our `_root.scss` file.
+
+```css
+{{< root.inline >}}
+{{- $css := readFile "dist/css/bootstrap.css" -}}
+{{- $match := findRE ":root {([^}]*)}" $css 1 -}}
+
+{{- if (eq (len $match) 0) -}}
+{{- errorf "Got no matches for :root in %q!" $.Page.Path -}}
+{{- end -}}
+
+{{- index $match 0 -}}
+
+{{< /root.inline >}}
+```
+
+### Examples
+
+CSS variables offer similar flexibility to Sass's variables, but without the need for compilation before being served to the browser. For example, here we're resetting our page's font and link styles with CSS variables.
+
+```css
+body {
+  font: 1rem/1.5 var(--font-family-sans-serif);
+}
+a {
+  color: var(--blue);
+}
+```
+
+### Breakpoint variables
+
+While we originally included breakpoints in our CSS variables (e.g., `--breakpoint-md`), **these are not supported in media queries**, but they can still be used _within_ rulesets in media queries. These breakpoint variables remain in the compiled CSS for backward compatibility given they can be utilized by JavaScript. [Learn more in the spec](https://www.w3.org/TR/css-variables-1/#using-variables).
+
+Here's an example of **what's not supported:**
+
+```css
+@media (min-width: var(--breakpoint-sm)) {
+  ...
+}
+```
+
+And here's an example of **what is supported:**
+
+```css
+@media (min-width: 768px) {
+  .custom-element {
+    color: var(--primary);
+  }
+}
+```

+title: Webpack
+description: Learn how to include Bootstrap in your project using Webpack.
+group: getting-started
+toc: true
+---
+
+## Installing Bootstrap
+
+[Install bootstrap]({{< docsref "/getting-started/download#npm" >}}) as a Node.js module using npm.
+
+## Importing JavaScript
+
+Import [Bootstrap's JavaScript]({{< docsref "/getting-started/javascript" >}}) by adding this line to your app's entry point (usually `index.js` or `app.js`):
+
+```js
+import 'bootstrap';
+```
+
+Alternatively, you may **import plugins individually** as needed:
+
+```js
+import 'bootstrap/js/dist/util';
+import 'bootstrap/js/dist/alert';
+...
+```
+
+Bootstrap depends on [jQuery](https://jquery.com/) and [Popper](https://popper.js.org/),
+which are specified in the `peerDependencies` property; this means that you will have to make sure to add both of them
+to your `package.json` using `npm install --save jquery popper.js`.
+
+## Importing Styles
+
+### Importing Precompiled Sass
+
+To enjoy the full potential of Bootstrap and customize it to your needs, use the source files as a part of your project's bundling process.
+
+First, create your own `_custom.scss` and use it to override the [built-in custom variables]({{< docsref "/getting-started/theming" >}}). Then, use your main Sass file to import your custom variables, followed by Bootstrap:
+
+```scss
+@import "custom";
+@import "~bootstrap/scss/bootstrap";
+```
+
+For Bootstrap to compile, make sure you install and use the required loaders: [sass-loader](https://github.com/webpack-contrib/sass-loader), [postcss-loader](https://github.com/webpack-contrib/postcss-loader) with [Autoprefixer](https://github.com/postcss/autoprefixer#webpack). With minimal setup, your webpack config should include this rule or similar:
+
+```js
+...
+{
+  test: /\.(scss)$/,
+  use: [{
+    loader: 'style-loader', // inject CSS to page
+  }, {
+    loader: 'css-loader', // translates CSS into CommonJS modules
+  }, {
+    loader: 'postcss-loader', // Run postcss actions
+    options: {
+      plugins: function () { // postcss plugins, can be exported to postcss.config.js
+        return [
+          require('autoprefixer')
+        ];
+      }
+    }
+  }, {
+    loader: 'sass-loader' // compiles Sass to CSS
+  }]
+},
+...
+```
+
+### Importing Compiled CSS
+
+Alternatively, you may use Bootstrap's ready-to-use CSS by simply adding this line to your project's entry point:
+
+```js
+import 'bootstrap/dist/css/bootstrap.min.css';
+```
+
+In this case you may use your existing rule for `css` without any special modifications to webpack config, except you don't need `sass-loader` just [style-loader](https://github.com/webpack-contrib/style-loader) and [css-loader](https://github.com/webpack-contrib/css-loader).
+
+```js
+...
+module: {
+  rules: [
+    {
+      test: /\.css$/,
+      use: ['style-loader', 'css-loader']
+    }
+  ]
+}
+...
+```

+title: Grid system
+description: Use our powerful mobile-first flexbox grid to build layouts of all shapes and sizes thanks to a twelve column system, five default responsive tiers, Sass variables and mixins, and dozens of predefined classes.
+group: layout
+toc: true
+---
+
+## How it works
+
+Bootstrap's grid system uses a series of containers, rows, and columns to layout and align content. It's built with [flexbox](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Basic_Concepts_of_Flexbox) and is fully responsive. Below is an example and an in-depth look at how the grid comes together.
+
+**New to or unfamiliar with flexbox?** [Read this CSS Tricks flexbox guide](https://css-tricks.com/snippets/css/a-guide-to-flexbox/#flexbox-background) for background, terminology, guidelines, and code snippets.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-sm">
+      One of three columns
+    </div>
+    <div class="col-sm">
+      One of three columns
+    </div>
+    <div class="col-sm">
+      One of three columns
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+The above example creates three equal-width columns on small, medium, large, and extra large devices using our predefined grid classes. Those columns are centered in the page with the parent `.container`.
+
+Breaking it down, here's how it works:
+
+- Containers provide a means to center and horizontally pad your site's contents. Use `.container` for a responsive pixel width or `.container-fluid` for `width: 100%` across all viewport and device sizes.
+- Rows are wrappers for columns. Each column has horizontal `padding` (called a gutter) for controlling the space between them. This `padding` is then counteracted on the rows with negative margins. This way, all the content in your columns is visually aligned down the left side.
+- In a grid layout, content must be placed within columns and only columns may be immediate children of rows.
+- Thanks to flexbox, grid columns without a specified `width` will automatically layout as equal width columns. For example, four instances of `.col-sm` will each automatically be 25% wide from the small breakpoint and up. See the [auto-layout columns](#auto-layout-columns) section for more examples.
+- Column classes indicate the number of columns you'd like to use out of the possible 12 per row. So, if you want three equal-width columns across, you can use `.col-4`.
+- Column `width`s are set in percentages, so they're always fluid and sized relative to their parent element.
+- Columns have horizontal `padding` to create the gutters between individual columns, however, you can remove the `margin` from rows and `padding` from columns with `.no-gutters` on the `.row`.
+- To make the grid responsive, there are five grid breakpoints, one for each [responsive breakpoint]({{< docsref "/layout/overview#responsive-breakpoints" >}}): all breakpoints (extra small), small, medium, large, and extra large.
+- Grid breakpoints are based on minimum width media queries, meaning **they apply to that one breakpoint and all those above it** (e.g., `.col-sm-4` applies to small, medium, large, and extra large devices, but not the first `xs` breakpoint).
+- You can use predefined grid classes (like `.col-4`) or [Sass mixins](#sass-mixins) for more semantic markup.
+
+Be aware of the limitations and [bugs around flexbox](https://github.com/philipwalton/flexbugs), like the [inability to use some HTML elements as flex containers](https://github.com/philipwalton/flexbugs#flexbug-9).
+
+## Grid options
+
+While Bootstrap uses `em`s or `rem`s for defining most sizes, `px`s are used for grid breakpoints and container widths. This is because the viewport width is in pixels and does not change with the [font size](https://drafts.csswg.org/mediaqueries-3/#units).
+
+See how aspects of the Bootstrap grid system work across multiple devices with a handy table.
+
+<table class="table table-bordered table-striped">

+    </tr>
+  </tbody>
+</table>
+
+## Auto-layout columns
+
+Utilize breakpoint-specific column classes for easy column sizing without an explicit numbered class like `.col-sm-6`.
+
+### Equal-width
+
+For example, here are two grid layouts that apply to every device and viewport, from `xs` to `xl`. Add any number of unit-less classes for each breakpoint you need and every column will be the same width.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col">
+      1 of 2
+    </div>
+    <div class="col">
+      2 of 2
+    </div>
+  </div>
+  <div class="row">
+    <div class="col">
+      1 of 3
+    </div>
+    <div class="col">
+      2 of 3
+    </div>
+    <div class="col">
+      3 of 3
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### Equal-width multi-line
+
+Create equal-width columns that span multiple lines by inserting a `.w-100` where you want the columns to break to a new line. Make the breaks responsive by mixing `.w-100` with some [responsive display utilities]({{< docsref "/utilities/display" >}}).
+
+There was a [Safari flexbox bug](https://github.com/philipwalton/flexbugs#flexbug-11) that prevented this from working without an explicit `flex-basis` or `border`. There are workarounds for older browser versions, but they shouldn't be necessary if your target browsers don't fall into the buggy versions.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col">col</div>
+    <div class="col">col</div>
+    <div class="w-100"></div>
+    <div class="col">col</div>
+    <div class="col">col</div>
+  </div>
+</div>
+{{< /example >}}
+
+### Setting one column width
+
+Auto-layout for flexbox grid columns also means you can set the width of one column and have the sibling columns automatically resize around it. You may use predefined grid classes (as shown below), grid mixins, or inline widths. Note that the other columns will resize no matter the width of the center column.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col">
+      1 of 3
+    </div>
+    <div class="col-6">
+      2 of 3 (wider)
+    </div>
+    <div class="col">
+      3 of 3
+    </div>
+  </div>
+  <div class="row">
+    <div class="col">
+      1 of 3
+    </div>
+    <div class="col-5">
+      2 of 3 (wider)
+    </div>
+    <div class="col">
+      3 of 3
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### Variable width content
+
+Use `col-{breakpoint}-auto` classes to size columns based on the natural width of their content.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row justify-content-md-center">
+    <div class="col col-lg-2">
+      1 of 3
+    </div>
+    <div class="col-md-auto">
+      Variable width content
+    </div>
+    <div class="col col-lg-2">
+      3 of 3
+    </div>
+  </div>
+  <div class="row">
+    <div class="col">
+      1 of 3
+    </div>
+    <div class="col-md-auto">
+      Variable width content
+    </div>
+    <div class="col col-lg-2">
+      3 of 3
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+## Responsive classes
+
+Bootstrap's grid includes five tiers of predefined classes for building complex responsive layouts. Customize the size of your columns on extra small, small, medium, large, or extra large devices however you see fit.
+
+### All breakpoints
+
+For grids that are the same from the smallest of devices to the largest, use the `.col` and `.col-*` classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to `.col`.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col">col</div>
+    <div class="col">col</div>
+    <div class="col">col</div>
+    <div class="col">col</div>
+  </div>
+  <div class="row">
+    <div class="col-8">col-8</div>
+    <div class="col-4">col-4</div>
+  </div>
+</div>
+{{< /example >}}
+
+### Stacked to horizontal
+
+Using a single set of `.col-sm-*` classes, you can create a basic grid system that starts out stacked and becomes horizontal at the small breakpoint (`sm`).
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-sm-8">col-sm-8</div>
+    <div class="col-sm-4">col-sm-4</div>
+  </div>
+  <div class="row">
+    <div class="col-sm">col-sm</div>
+    <div class="col-sm">col-sm</div>
+    <div class="col-sm">col-sm</div>
+  </div>
+</div>
+{{< /example >}}
+
+### Mix and match
+
+Don't want your columns to simply stack in some grid tiers? Use a combination of different classes for each tier as needed. See the example below for a better idea of how it all works.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <!-- Stack the columns on mobile by making one full-width and the other half-width -->
+  <div class="row">
+    <div class="col-md-8">.col-md-8</div>
+    <div class="col-6 col-md-4">.col-6 .col-md-4</div>
+  </div>
+
+  <!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
+  <div class="row">
+    <div class="col-6 col-md-4">.col-6 .col-md-4</div>
+    <div class="col-6 col-md-4">.col-6 .col-md-4</div>
+    <div class="col-6 col-md-4">.col-6 .col-md-4</div>
+  </div>
+
+  <!-- Columns are always 50% wide, on mobile and desktop -->
+  <div class="row">
+    <div class="col-6">.col-6</div>
+    <div class="col-6">.col-6</div>
+  </div>
+</div>
+{{< /example >}}
+
+### Gutters
+
+Gutters can be responsively adjusted by breakpoint-specific padding and negative margin utility classes. To change the gutters in a given row, pair a negative margin utility on the `.row` and matching padding utilities on the `.col`s. The `.container` or `.container-fluid` parent may need to be adjusted too to avoid unwanted overflow, using again matching padding utility.
+
+Here's an example of customizing the Bootstrap grid at the large (`lg`) breakpoint and above. We've increased the `.col` padding with `.px-lg-5`, counteracted that with `.mx-lg-n5` on the parent `.row` and then adjusted the `.container` wrapper with `.px-lg-5`.
+
+{{< example >}}
+<div class="container px-lg-5">
+  <div class="row mx-lg-n5">
+    <div class="col py-3 px-lg-5 border bg-light">Custom column padding</div>
+    <div class="col py-3 px-lg-5 border bg-light">Custom column padding</div>
+  </div>
+</div>
+{{< /example >}}
+
+### Row columns
+
+Use the responsive `.row-cols-*` classes to quickly set the number of columns that best render your content and layout. Whereas normal `.col-*` classes apply to the individual columns (e.g., `.col-md-4`), the row columns classes are set on the parent `.row` as a shortcut.
+
+Use these row columns classes to quickly create basic grid layouts or to control your card layouts.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row row-cols-2">
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row row-cols-3">
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row row-cols-4">
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row row-cols-4">
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col-6">Column</div>
+    <div class="col">Column</div>
+  </div>
+</div>
+{{< /example >}}
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row row-cols-1 row-cols-sm-2 row-cols-md-4">
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+    <div class="col">Column</div>
+  </div>
+</div>
+{{< /example >}}
+
+You can also use the accompanying Sass mixin, `row-cols()`:
+
+```scss
+.element {
+  // Three columns to start
+  @include row-cols(3);
+
+  // Five columns from medium breakpoint up
+  @include media-breakpoint-up(md) {
+    @include row-cols(5);
+  }
+}
+```
+
+## Alignment
+
+Use flexbox alignment utilities to vertically and horizontally align columns. **Internet Explorer 10-11 do not support vertical alignment of flex items when the flex container has a `min-height` as shown below.** [See Flexbugs #3 for more details.](https://github.com/philipwalton/flexbugs#flexbug-3)
+
+### Vertical alignment
+
+{{< example class="bd-example-row bd-example-row-flex-cols" >}}
+<div class="container">
+  <div class="row align-items-start">
+    <div class="col">
+      One of three columns
+    </div>
+    <div class="col">
+      One of three columns
+    </div>
+    <div class="col">
+      One of three columns
+    </div>
+  </div>
+  <div class="row align-items-center">
+    <div class="col">

+    <div class="col">

+  </div>
+</div>
+{{< /example >}}
+
+{{< example class="bd-example-row bd-example-row-flex-cols" >}}
+<div class="container">
+  <div class="row">
+    <div class="col align-self-start">

+    </div>
+    <div class="col align-self-center">

+    <div class="col align-self-end">
+      One of three columns
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### Horizontal alignment
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row justify-content-start">
+    <div class="col-4">
+      One of two columns
+    </div>
+    <div class="col-4">
+      One of two columns
+    </div>
+  </div>
+  <div class="row justify-content-center">
+    <div class="col-4">
+      One of two columns
+    </div>
+    <div class="col-4">
+      One of two columns
+    </div>
+  </div>
+  <div class="row justify-content-end">
+    <div class="col-4">

+    </div>
+  </div>
+  <div class="row justify-content-around">
+    <div class="col-4">
+      One of two columns
+    </div>
+    <div class="col-4">

+      One of two columns
+    </div>
+    <div class="col-4">
+      One of two columns
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### No gutters
+
+The gutters between columns in our predefined grid classes can be removed with `.no-gutters`. This removes the negative `margin`s from `.row` and the horizontal `padding` from all immediate children columns.
+
+Here's the source code for creating these styles. Note that column overrides are scoped to only the first children columns and are targeted via [attribute selector](https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors). While this generates a more specific selector, column padding can still be further customized with [spacing utilities]({{< docsref "/utilities/spacing" >}}).
+
+**Need an edge-to-edge design?** Drop the parent `.container` or `.container-fluid`.
+
+```scss
+.no-gutters {
+  margin-right: 0;
+  margin-left: 0;
+
+  > .col,
+  > [class*="col-"] {
+    padding-right: 0;
+    padding-left: 0;
+  }
+}
+```
+
+In practice, here's how it looks. Note you can continue to use this with all other predefined grid classes (including column widths, responsive tiers, reorders, and more).
+
+{{< example class="bd-example-row" >}}
+<div class="row no-gutters">
+  <div class="col-sm-6 col-md-8">.col-sm-6 .col-md-8</div>
+  <div class="col-6 col-md-4">.col-6 .col-md-4</div>
+</div>
+{{< /example >}}
+
+### Column wrapping
+
+If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-9">.col-9</div>
+    <div class="col-4">.col-4<br>Since 9 + 4 = 13 &gt; 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.</div>
+    <div class="col-6">.col-6<br>Subsequent columns continue along the new line.</div>
+  </div>
+</div>
+{{< /example >}}
+
+### Column breaks
+
+Breaking columns to a new line in flexbox requires a small hack: add an element with `width: 100%` wherever you want to wrap your columns to a new line. Normally this is accomplished with multiple `.row`s, but not every implementation method can account for this.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
+    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
+
+    <!-- Force next columns to break to new line -->
+    <div class="w-100"></div>
+
+    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
+    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
+  </div>
+</div>
+{{< /example >}}
+
+You may also apply this break at specific breakpoints with our [responsive display utilities]({{< docsref "/utilities/display" >}}).
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
+    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
+
+    <!-- Force next columns to break to new line at md breakpoint and up -->
+    <div class="w-100 d-none d-md-block"></div>
+
+    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
+    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
+  </div>
+</div>
+{{< /example >}}
+
+## Reordering
+
+### Order classes
+
+Use `.order-` classes for controlling the **visual order** of your content. These classes are responsive, so you can set the `order` by breakpoint (e.g., `.order-1.order-md-2`). Includes support for `1` through `12` across all five grid tiers.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col">
+      First in DOM, no order applied
+    </div>
+    <div class="col order-12">
+      Second in DOM, with a larger order
+    </div>
+    <div class="col order-1">
+      Third in DOM, with an order of 1
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+There are also responsive `.order-first` and `.order-last` classes that change the `order` of an element by applying `order: -1` and `order: 13` (`order: $columns + 1`), respectively. These classes can also be intermixed with the numbered `.order-*` classes as needed.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col order-last">
+      First in DOM, ordered last
+    </div>
+    <div class="col">
+      Second in DOM, unordered
+    </div>
+    <div class="col order-first">
+      Third in DOM, ordered first
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+### Offsetting columns
+
+You can offset grid columns in two ways: our responsive `.offset-` grid classes and our [margin utilities]({{< docsref "/utilities/spacing" >}}). Grid classes are sized to match columns while margins are more useful for quick layouts where the width of the offset is variable.
+
+#### Offset classes
+
+Move columns to the right using `.offset-md-*` classes. These classes increase the left margin of a column by `*` columns. For example, `.offset-md-4` moves `.col-md-4` over four columns.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-md-4">.col-md-4</div>
+    <div class="col-md-4 offset-md-4">.col-md-4 .offset-md-4</div>
+  </div>
+  <div class="row">
+    <div class="col-md-3 offset-md-3">.col-md-3 .offset-md-3</div>
+    <div class="col-md-3 offset-md-3">.col-md-3 .offset-md-3</div>
+  </div>
+  <div class="row">
+    <div class="col-md-6 offset-md-3">.col-md-6 .offset-md-3</div>
+  </div>
+</div>
+{{< /example >}}
+
+In addition to column clearing at responsive breakpoints, you may need to reset offsets. See this in action in [the grid example]({{< docsref "/examples/grid" >}}).
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
+    <div class="col-sm-5 offset-sm-2 col-md-6 offset-md-0">.col-sm-5 .offset-sm-2 .col-md-6 .offset-md-0</div>
+  </div>
+  <div class="row">
+    <div class="col-sm-6 col-md-5 col-lg-6">.col-sm-6 .col-md-5 .col-lg-6</div>
+    <div class="col-sm-6 col-md-5 offset-md-2 col-lg-6 offset-lg-0">.col-sm-6 .col-md-5 .offset-md-2 .col-lg-6 .offset-lg-0</div>
+  </div>
+</div>
+{{< /example >}}
+
+#### Margin utilities
+
+With the move to flexbox in v4, you can use margin utilities like `.mr-auto` to force sibling columns away from one another.
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-md-4">.col-md-4</div>
+    <div class="col-md-4 ml-auto">.col-md-4 .ml-auto</div>
+  </div>
+  <div class="row">
+    <div class="col-md-3 ml-md-auto">.col-md-3 .ml-md-auto</div>
+    <div class="col-md-3 ml-md-auto">.col-md-3 .ml-md-auto</div>
+  </div>
+  <div class="row">
+    <div class="col-auto mr-auto">.col-auto .mr-auto</div>
+    <div class="col-auto">.col-auto</div>
+  </div>
+</div>
+{{< /example >}}
+
+## Nesting
+
+To nest your content with the default grid, add a new `.row` and set of `.col-sm-*` columns within an existing `.col-sm-*` column. Nested rows should include a set of columns that add up to 12 or fewer (it is not required that you use all 12 available columns).
+
+{{< example class="bd-example-row" >}}
+<div class="container">
+  <div class="row">
+    <div class="col-sm-9">
+      Level 1: .col-sm-9
+      <div class="row">
+        <div class="col-8 col-sm-6">
+          Level 2: .col-8 .col-sm-6
+        </div>
+        <div class="col-4 col-sm-6">
+          Level 2: .col-4 .col-sm-6
+        </div>
+      </div>
+    </div>
+  </div>
+</div>
+{{< /example >}}
+
+## Sass mixins
+
+When using Bootstrap's source Sass files, you have the option of using Sass variables and mixins to create custom, semantic, and responsive page layouts. Our predefined grid classes use these same variables and mixins to provide a whole suite of ready-to-use classes for fast responsive layouts.
+
+### Variables
+
+Variables and maps determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.
+
+```scss
+$grid-columns:      12;
+$grid-gutter-width: 30px;
+
+$grid-breakpoints: (
+  // Extra small screen / phone
+  xs: 0,
+  // Small screen / phone
+  sm: 576px,
+  // Medium screen / tablet
+  md: 768px,
+  // Large screen / desktop
+  lg: 992px,
+  // Extra large screen / wide desktop
+  xl: 1200px
+);
+
+$container-max-widths: (
+  sm: 540px,
+  md: 720px,
+  lg: 960px,
+  xl: 1140px
+);
+```
+
+### Mixins
+
+Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.
+
+```scss
+// Creates a wrapper for a series of columns
+@include make-row();
+
+// Make the element grid-ready (applying everything but the width)
+@include make-col-ready();
+@include make-col($size, $columns: $grid-columns);
+
+// Get fancy by offsetting, or changing the sort order
+@include make-col-offset($size, $columns: $grid-columns);
+```
+
+### Example usage
+
+You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.
+
+```scss
+.example-container {
+  @include make-container();
+  // Make sure to define this width after the mixin to override
+  // `width: 100%` generated by `make-container()`
+  width: 800px;
+}
+
+.example-row {
+  @include make-row();
+}
+
+.example-content-main {
+  @include make-col-ready();
+
+  @include media-breakpoint-up(sm) {
+    @include make-col(6);
+  }
+  @include media-breakpoint-up(lg) {
+    @include make-col(8);
+  }
+}
+
+.example-content-secondary {
+  @include make-col-ready();
+
+  @include media-breakpoint-up(sm) {
+    @include make-col(6);
+  }
+  @include media-breakpoint-up(lg) {
+    @include make-col(4);
+  }
+}
+```
+
+{{< example >}}
+<div class="example-container">
+  <div class="example-row">
+    <div class="example-content-main">Main content</div>
+    <div class="example-content-secondary">Secondary content</div>
+  </div>
+</div>
+{{< /example >}}
+
+## Customizing the grid
+
+Using our built-in grid Sass variables and maps, it's possible to completely customize the predefined grid classes. Change the number of tiers, the media query dimensions, and the container widths—then recompile.
+
+### Columns and gutters
+
+The number of grid columns can be modified via Sass variables. `$grid-columns` is used to generate the widths (in percent) of each individual column while `$grid-gutter-width` sets the width for the column gutters.
+
+```scss
+$grid-columns: 12 !default;
+$grid-gutter-width: 30px !default;
+```
+
+### Grid tiers
+
+Moving beyond the columns themselves, you may also customize the number of grid tiers. If you wanted just four grid tiers, you'd update the `$grid-breakpoints` and `$container-max-widths` to something like this:
+
+```scss
+$grid-breakpoints: (
+  xs: 0,
+  sm: 480px,
+  md: 768px,
+  lg: 1024px
+);
+
+$container-max-widths: (
+  sm: 420px,
+  md: 720px,
+  lg: 960px
+);
+```
+
+When making any changes to the Sass variables or maps, you'll need to save your changes and recompile. Doing so will output a brand new set of predefined grid classes for column widths, offsets, and ordering. Responsive visibility utilities will also be updated to use the custom breakpoints. Make sure to set grid values in `px` (not `rem`, `em`, or `%`).

+
+## Containers
+
+Containers are the most basic layout element in Bootstrap and are **required when using our default grid system**. Containers are used to contain, pad, and (sometimes) center the content within them. While containers *can* be nested, most layouts do not require a nested container.
+
+Bootstrap comes with three different containers:
+
+- `.container`, which sets a `max-width` at each responsive breakpoint
+- `.container-fluid`, which is `width: 100%` at all breakpoints
+- `.container-{breakpoint}`, which is `width: 100%` until the specified breakpoint
+
+The table below illustrates how each container's `max-width` compares to the original `.container` and `.container-fluid` across each breakpoint.
+
+See them in action and compare them in our [Grid example]({{< docsref "/examples/grid#containers" >}}).
+
+<table class="table">
+  <thead>
+    <tr>
+      <th></th>
+      <th>
+        Extra small<br>
+        <span class="font-weight-normal">&lt;576px</span>
+      </th>
+      <th>

+
+### All-in-one
+
+Our default `.container` class is a responsive, fixed-width container, meaning its `max-width` changes at each breakpoint.
+
+```html
+<div class="container">
+  <!-- Content here -->
+</div>
+```
+
+### Fluid
+
+Use `.container-fluid` for a full width container, spanning the entire width of the viewport.
+
+```html
+<div class="container-fluid">
+  ...
+</div>
+```
+
+### Responsive
+
+Responsive containers are new in Bootstrap v4.4. They allow you to specify a class that is 100% wide until the specified breakpoint is reached, after which we apply `max-width`s for each of the higher breakpoints. For example, `.container-sm` is 100% wide to start until the `sm` breakpoint is reached, where it will scale up with `md`, `lg`, and `xl`.
+
+```html
+<div class="container-sm">100% wide until small breakpoint</div>
+<div class="container-md">100% wide until medium breakpoint</div>
+<div class="container-lg">100% wide until large breakpoint</div>
+<div class="container-xl">100% wide until extra large breakpoint</div>
+```
+
+## Responsive breakpoints
+
+Since Bootstrap is developed to be mobile first, we use a handful of [media queries](https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries) to create sensible breakpoints for our layouts and interfaces. These breakpoints are mostly based on minimum viewport widths and allow us to scale up elements as the viewport changes.
+
+Bootstrap primarily uses the following media query ranges—or breakpoints—in our source Sass files for our layout, grid system, and components.
+
+```scss
+// Extra small devices (portrait phones, less than 576px)
+// No media query for `xs` since this is the default in Bootstrap
+
+// Small devices (landscape phones, 576px and up)
+@media (min-width: 576px) { ... }
+
+// Medium devices (tablets, 768px and up)
+@media (min-width: 768px) { ... }
+
+// Large devices (desktops, 992px and up)
+@media (min-width: 992px) { ... }
+
+// Extra large devices (large desktops, 1200px and up)
+@media (min-width: 1200px) { ... }
+```
+
+Since we write our source CSS in Sass, all our media queries are available via Sass mixins:
+
+```scss
+// No media query necessary for xs breakpoint as it's effectively `@media (min-width: 0) { ... }`
+@include media-breakpoint-up(sm) { ... }
+@include media-breakpoint-up(md) { ... }
+@include media-breakpoint-up(lg) { ... }
+@include media-breakpoint-up(xl) { ... }
+
+// Example: Hide starting at `min-width: 0`, and then show at the `sm` breakpoint
+.custom-class {
+  display: none;
+}
+@include media-breakpoint-up(sm) {
+  .custom-class {
+    display: block;
+  }
+}
+```
+
+We occasionally use media queries that go in the other direction (the given screen size *or smaller*):
+
+```scss
+// Extra small devices (portrait phones, less than 576px)
+@media (max-width: 575.98px) { ... }
+
+// Small devices (landscape phones, less than 768px)
+@media (max-width: 767.98px) { ... }
+
+// Medium devices (tablets, less than 992px)
+@media (max-width: 991.98px) { ... }
+
+// Large devices (desktops, less than 1200px)
+@media (max-width: 1199.98px) { ... }
+
+// Extra large devices (large desktops)
+// No media query since the extra-large breakpoint has no upper bound on its width
+```
+
+{{< callout info >}}
+{{< partial "callout-info-mediaqueries-breakpoints.md" >}}
+{{< /callout >}}
+
+Once again, these media queries are also available via Sass mixins:
+
+```scss
+@include media-breakpoint-down(xs) { ... }
+@include media-breakpoint-down(sm) { ... }
+@include media-breakpoint-down(md) { ... }
+@include media-breakpoint-down(lg) { ... }
+// No media query necessary for xl breakpoint as it has no upper bound on its width
+
+// Example: Style from medium breakpoint and down
+@include media-breakpoint-down(md) {
+  .custom-class {
+    display: block;
+  }
+}
+```
+
+There are also media queries and mixins for targeting a single segment of screen sizes using the minimum and maximum breakpoint widths.
+
+```scss
+// Extra small devices (portrait phones, less than 576px)
+@media (max-width: 575.98px) { ... }
+
+// Small devices (landscape phones, 576px and up)
+@media (min-width: 576px) and (max-width: 767.98px) { ... }
+
+// Medium devices (tablets, 768px and up)
+@media (min-width: 768px) and (max-width: 991.98px) { ... }
+
+// Large devices (desktops, 992px and up)
+@media (min-width: 992px) and (max-width: 1199.98px) { ... }
+
+// Extra large devices (large desktops, 1200px and up)
+@media (min-width: 1200px) { ... }
+```
+
+These media queries are also available via Sass mixins:
+
+```scss
+@include media-breakpoint-only(xs) { ... }
+@include media-breakpoint-only(sm) { ... }
+@include media-breakpoint-only(md) { ... }
+@include media-breakpoint-only(lg) { ... }
+@include media-breakpoint-only(xl) { ... }
+```
+
+Similarly, media queries may span multiple breakpoint widths:
+
+```scss
+// Example
+// Apply styles starting from medium devices and up to extra large devices
+@media (min-width: 768px) and (max-width: 1199.98px) { ... }
+```
+
+The Sass mixin for targeting the same screen size range would be:
+
+```scss
+@include media-breakpoint-between(md, xl) { ... }
+```
+
+## Z-index
+
+Several Bootstrap components utilize `z-index`, the CSS property that helps control layout by providing a third axis to arrange content. We utilize a default z-index scale in Bootstrap that's been designed to properly layer navigation, tooltips and popovers, modals, and more.
+
+These higher values start at an arbitrary number, high and specific enough to ideally avoid conflicts. We need a standard set of these across our layered components—tooltips, popovers, navbars, dropdowns, modals—so we can be reasonably consistent in the behaviors. There's no reason we couldn't have used `100`+ or `500`+.
+
+We don't encourage customization of these individual values; should you change one, you likely need to change them all.
+
+```scss
+$zindex-dropdown:          1000 !default;
+$zindex-sticky:            1020 !default;
+$zindex-fixed:             1030 !default;
+$zindex-modal-backdrop:    1040 !default;
+$zindex-modal:             1050 !default;
+$zindex-popover:           1060 !default;
+$zindex-tooltip:           1070 !default;
+```
+
+To handle overlapping borders within components (e.g., buttons and inputs in input groups), we use low single digit `z-index` values of `1`, `2`, and `3` for default, hover, and active states. On hover/focus/active, we bring a particular element to the forefront with a higher `z-index` value to show their border over the sibling elements.

+title: Utilities for layout
+description: For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
+group: layout
+toc: true
+---
+
+## Changing `display`
+
+Use our [display utilities]({{< docsref "/utilities/display" >}}) for responsively toggling common values of the `display` property. Mix it with our grid system, content, or components to show or hide them across specific viewports.
+
+## Flexbox options
+
+Bootstrap 4 is built with flexbox, but not every element's `display` has been changed to `display: flex` as this would add many unnecessary overrides and unexpectedly change key browser behaviors. Most of [our components]({{< docsref "/components/alerts" >}}) are built with flexbox enabled.
+
+Should you need to add `display: flex` to an element, do so with `.d-flex` or one of the responsive variants (e.g., `.d-sm-flex`). You'll need this class or `display` value to allow the use of our extra [flexbox utilities]({{< docsref "/utilities/flex" >}}) for sizing, alignment, spacing, and more.
+
+## Margin and padding
+
+Use the `margin` and `padding` [spacing utilities]({{< docsref "/utilities/spacing" >}}) to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities, based on a `1rem` value default `$spacer` variable. Choose values for all viewports (e.g., `.mr-3` for `margin-right: 1rem`), or pick responsive variants to target specific viewports (e.g., `.mr-md-3` for `margin-right: 1rem` starting at the `md` breakpoint).
+
+## Toggle `visibility`
+
+When toggling `display` isn't needed, you can toggle the `visibility` of an element with our [visibility utilities]({{< docsref "/utilities/visibility" >}}). Invisible elements will still affect the layout of the page, but are visually hidden from visitors.

+title: Migrating to v4
+description: Bootstrap 4 is a major rewrite of the entire project. The most notable changes are summarized below, followed by more specific changes to relevant components.
+group: migration
+aliases: "/migration/"
+toc: true
+---
+
+## Stable changes
+
+Moving from Beta 3 to our stable v4.x release, there are no breaking changes, but there are some notable changes.
+
+### Printing
+- Fixed broken print utilities. Previously, using a `.d-print-*` class would unexpectedly overrule any other `.d-*` class. Now, they match our other display utilities and only apply to that media (`@media print`).
+
+- Expanded available print display utilities to match other utilities. Beta 3 and older only had `block`, `inline-block`, `inline`, and `none`. Stable v4 added `flex`, `inline-flex`, `table`, `table-row`, and `table-cell`.
+
+- Fixed print preview rendering across browsers with new print styles that specify `@page` `size`.
+
+## Beta 3 changes
+
+While Beta 2 saw the bulk of our breaking changes during the beta phase, but we still have a few that needed to be addressed in the Beta 3 release. These changes apply if you're updating to Beta 3 from Beta 2 or any older version of Bootstrap.
+
+### Miscellaneous
+
+- Removed the unused `$thumbnail-transition` variable. We weren't transitioning anything, so it was just extra code.
+- The npm package no longer includes any files other than our source and dist files; if you relied on them and were running our scripts via the `node_modules` folder, you should adapt your workflow.
+
+### Forms
+
+- Rewrote both custom and default checkboxes and radios. Now, both have matching HTML structure (outer `<div>` with sibling `<input>` and `<label>`) and the same layout styles (stacked default, inline with modifier class). This allows us to style the label based on the input's state, simplifying support for the `disabled` attribute (previously requiring a parent class) and better supporting our form validation.
+
+  As part of this, we've changed the CSS for managing multiple `background-image`s on custom form checkboxes and radios. Previously, the now removed `.custom-control-indicator` element had the background color, gradient, and SVG icon. Customizing the background gradient meant replacing all of those every time you needed to change just one. Now, we have `.custom-control-label::before` for the fill and gradient and `.custom-control-label::after` handles the icon.
+
+  To make a custom check inline, add `.custom-control-inline`.
+
+- Updated selector for input-based button groups. Instead of `[data-toggle="buttons"] { }` for style and behavior, we use the `data` attribute just for JS behaviors and rely on a new `.btn-group-toggle` class for styling.
+
+- Removed `.col-form-legend` in favor of a slightly improved `.col-form-label`. This way `.col-form-label-sm` and `.col-form-label-lg` can be used on `<legend>` elements with ease.
+
+- Custom file inputs received a change to their `$custom-file-text` Sass variable. It's no longer a nested Sass map and now only powers one string—the `Browse` button as that is now the only pseudo-element generated from our Sass. The `Choose file` text now comes from the `.custom-file-label`.
+
+### Input groups
+
+- Input group addons are now specific to their placement relative to an input. We've dropped `.input-group-addon` and `.input-group-btn` for two new classes, `.input-group-prepend` and `.input-group-append`. You must explicitly use an append or a prepend now, simplifying much of our CSS. Within an append or prepend, place your buttons as they would exist anywhere else, but wrap text in `.input-group-text`.
+
+- Validation styles are now supported, as are multiple inputs (though you can only validate one input per group).
+
+- Sizing classes must be on the parent `.input-group` and not the individual form elements.
+
+## Beta 2 changes
+
+While in beta, we aim to have no breaking changes. However, things don't always go as planned. Below are the breaking changes to bear in mind when moving from Beta 1 to Beta 2.
+
+### Breaking
+
+- Removed `$badge-color` variable and its usage on `.badge`. We use a color contrast function to pick a `color` based on the `background-color`, so the variable is unnecessary.
+- Renamed `grayscale()` function to `gray()` to avoid breaking conflict with the CSS native `grayscale` filter.
+- Renamed `.table-inverse`, `.thead-inverse`, and `.thead-default` to `.*-dark` and `.*-light`, matching our color schemes used elsewhere.
+- Responsive tables now generate classes for each grid breakpoint. This breaks from Beta 1 in that the `.table-responsive` you've been using is more like `.table-responsive-md`. You may now use `.table-responsive` or `.table-responsive-{sm,md,lg,xl}` as needed.
+- Dropped Bower support as the package manager has been deprecated for alternatives (e.g., Yarn or npm). [See bower/bower#2298](https://github.com/bower/bower/issues/2298) for details.
+- Bootstrap still requires jQuery 1.9.1 or higher, but you're advised to use version 3.x since v3.x's supported browsers are the ones Bootstrap supports plus v3.x has some security fixes.
+- Removed the unused `.form-control-label` class. If you did make use of this class, it was duplicate of the `.col-form-label` class that vertically centered a `<label>` with it's associated input in horizontal form layouts.
+- Changed the `color-yiq` from a mixin that included the `color` property to a function that returns a value, allowing you to use it for any CSS property. For example, instead of `color-yiq(#000)`, you'd write `color: color-yiq(#000);`.
+
+### Highlights
+
+- Introduced new `pointer-events` usage on modals. The outer `.modal-dialog` passes through events with `pointer-events: none` for custom click handling (making it possible to just listen on the `.modal-backdrop` for any clicks), and then counteracts it for the actual `.modal-content` with `pointer-events: auto`.
+
+
+## Summary
+
+Here are the big ticket items you'll want to be aware of when moving from v3 to v4.
+
+### Browser support
+
+- Dropped IE8, IE9, and iOS 6 support. v4 is now only IE10+ and iOS 7+. For sites needing either of those, use v3.
+- Added official support for Android v5.0 Lollipop's Browser and WebView. Earlier versions of the Android Browser and WebView remain only unofficially supported.
+
+### Global changes
+
+- **Flexbox is enabled by default.** In general this means a move away from floats and more across our components.
+- Switched from [Less](http://lesscss.org/) to [Sass](https://sass-lang.com/) for our source CSS files.
+- Switched from `px` to `rem` as our primary CSS unit, though pixels are still used for media queries and grid behavior as device viewports are not affected by type size.
+- Global font-size increased from `14px` to `16px`.
+- Revamped grid tiers to add a fifth option (addressing smaller devices at `576px` and below) and removed the `-xs` infix from those classes. Example: `.col-6.col-sm-4.col-md-3`.
+- Replaced the separate optional theme with configurable options via SCSS variables (e.g., `$enable-gradients: true`).
+- Build system overhauled to use a series of npm scripts instead of Grunt. See `package.json` for all scripts, or our project readme for local development needs.
+- Non-responsive usage of Bootstrap is no longer supported.
+- Dropped the online Customizer in favor of more extensive setup documentation and customized builds.
+- Added dozens of new [utility classes](/docs/{{< param docs_version >}}/utilities/) for common CSS property-value pairs and margin/padding spacing shortcuts.
+
+### Grid system
+
+- **Moved to flexbox.**
+  - Added support for flexbox in the grid mixins and predefined classes.
+  - As part of flexbox, included support for vertical and horizontal alignment classes.
+- **Updated grid class names and a new grid tier.**
+  - Added a new `sm` grid tier below `768px` for more granular control. We now have `xs`, `sm`, `md`, `lg`, and `xl`. This also means every tier has been bumped up one level (so `.col-md-6` in v3 is now `.col-lg-6` in v4).
+  - `xs` grid classes have been modified to not require the infix to more accurately represent that they start applying styles at `min-width: 0` and not a set pixel value. Instead of `.col-xs-6`, it's now `.col-6`. All other grid tiers require the infix (e.g., `sm`).
+- **Updated grid sizes, mixins, and variables.**
+  - Grid gutters now have a Sass map so you can specify specific gutter widths at each breakpoint.
+  - Updated grid mixins to utilize a `make-col-ready` prep mixin and a `make-col` to set the `flex` and `max-width` for individual column sizing.
+  - Changed grid system media query breakpoints and container widths to account for new grid tier and ensure columns are evenly divisible by `12` at their max width.
+  - Grid breakpoints and container widths are now handled via Sass maps (`$grid-breakpoints` and `$container-max-widths`) instead of a handful of separate variables. These replace the `@screen-*` variables entirely and allow you to fully customize the grid tiers.
+  - Media queries have also changed. Instead of repeating our media query declarations with the same value each time, we now have `@include media-breakpoint-up/down/only`. Now, instead of writing `@media (min-width: @screen-sm-min) { ... }`, you can write `@include media-breakpoint-up(sm) { ... }`.
+
+### Components
+
+- **Dropped panels, thumbnails, and wells** for a new all-encompassing component, [cards]({{< docsref "/components/card" >}}).
+- **Dropped the Glyphicons icon font.** If you need icons, some options are:
+  - the upstream version of [Glyphicons](https://www.glyphicons.com/)
+  - [Octicons](https://octicons.github.com/)
+  - [Font Awesome](https://fontawesome.com/)
+  - See the [Extend page]({{< docsref "/extend/icons" >}}) for a list of alternatives. Have additional suggestions? Please open an issue or PR.
+- **Dropped the Affix jQuery plugin.**
+  - We recommend using `position: sticky` instead. [See the HTML5 Please entry](https://html5please.com/#sticky) for details and specific polyfill recommendations. One suggestion is to use an `@supports` rule for implementing it (e.g., `@supports (position: sticky) { ... }`)
+  - If you were using Affix to apply additional, non-`position` styles, the polyfills might not support your use case. One option for such uses is the third-party [ScrollPos-Styler](https://github.com/acch/scrollpos-styler) library.
+- **Dropped the pager component** as it was essentially slightly customized buttons.
+- **Refactored nearly all components** to use more un-nested class selectors instead of over-specific children selectors.
+
+## By component
+
+This list highlights key changes by component between v3.x.x and v4.0.0.
+
+### Reboot
+
+New to Bootstrap 4 is the [Reboot]({{< docsref "/content/reboot" >}}), a new stylesheet that builds on Normalize with our own somewhat opinionated reset styles. Selectors appearing in this file only use elements—there are no classes here. This isolates our reset styles from our component styles for a more modular approach. Some of the most important resets this includes are the `box-sizing: border-box` change, moving from `em` to `rem` units on many elements, link styles, and many form element resets.
+
+### Typography
+
+- Moved all `.text-` utilities to the `_utilities.scss` file.
+- Dropped `.page-header` as its styles can be applied via utilities.
+- `.dl-horizontal` has been dropped. Instead, use `.row` on `<dl>` and use grid column classes (or mixins) on its `<dt>` and `<dd>` children.
+- Redesigned blockquotes, moving their styles from the `<blockquote>` element to a single class, `.blockquote`. Dropped the `.blockquote-reverse` modifier for text utilities.
+- `.list-inline` now requires that its children list items have the new `.list-inline-item` class applied to them.
+
+### Images
+
+- Renamed `.img-responsive` to `.img-fluid`.
+- Renamed `.img-rounded` to `.rounded`
+- Renamed `.img-circle` to `.rounded-circle`
+
+### Tables
+
+- Nearly all instances of the `>` selector have been removed, meaning nested tables will now automatically inherit styles from their parents. This greatly simplifies our selectors and potential customizations.
+- Renamed `.table-condensed` to `.table-sm` for consistency.
+- Added a new `.table-inverse` option.
+- Added table header modifiers: `.thead-default` and `.thead-inverse`.
+- Renamed contextual classes to have a `.table-`-prefix. Hence `.active`, `.success`, `.warning`, `.danger` and `.info` to `.table-active`, `.table-success`, `.table-warning`, `.table-danger` and `.table-info`.
+
+### Forms
+
+- Moved element resets to the `_reboot.scss` file.
+- Renamed `.control-label` to `.col-form-label`.
+- Renamed `.input-lg` and `.input-sm` to `.form-control-lg` and `.form-control-sm`, respectively.
+- Dropped `.form-group-*` classes for simplicity's sake. Use `.form-control-*` classes instead now.
+- Dropped `.help-block` and replaced it with `.form-text` for block-level help text. For inline help text and other flexible options, use utility classes like `.text-muted`.
+- Dropped `.radio-inline` and `.checkbox-inline`.
+- Consolidated `.checkbox` and `.radio` into `.form-check` and the various `.form-check-*` classes.
+- Horizontal forms overhauled:
+  - Dropped the `.form-horizontal` class requirement.
+  - `.form-group` no longer applies styles from the `.row` via mixin, so `.row` is now required for horizontal grid layouts (e.g., `<div class="form-group row">`).
+  - Added new `.col-form-label` class to vertically center labels with `.form-control`s.
+  - Added new `.form-row` for compact form layouts with the grid classes (swap your `.row` for a `.form-row` and go).
+- Added custom forms support (for checkboxes, radios, selects, and file inputs).
+- Replaced `.has-error`, `.has-warning`, and `.has-success` classes with HTML5 form validation via CSS's `:invalid` and `:valid` pseudo-classes.
+- Renamed `.form-control-static` to `.form-control-plaintext`.
+
+### Buttons
+
+- Renamed `.btn-default` to `.btn-secondary`.
+- Dropped the `.btn-xs` class entirely as `.btn-sm` is proportionally much smaller than v3's.
+- The [stateful button](https://getbootstrap.com/docs/3.3/javascript/#buttons-stateful) feature of the `button.js` jQuery plugin has been dropped. This includes the `$().button(string)` and `$().button('reset')` methods. We advise using a tiny bit of custom JavaScript instead, which will have the benefit of behaving exactly the way you want it to.
+  - Note that the other features of the plugin (button checkboxes, button radios, single-toggle buttons) have been retained in v4.
+- Change buttons' `[disabled]` to `:disabled` as IE9+ supports `:disabled`. However `fieldset[disabled]` is still necessary because [native disabled fieldsets are still buggy in IE11](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/fieldset#Browser_compatibility).
+
+### Button group
+
+- Rewrote component with flexbox.
+- Removed `.btn-group-justified`. As a replacement you can use `<div class="btn-group d-flex" role="group"></div>` as a wrapper around elements with `.w-100`.
+- Dropped the `.btn-group-xs` class entirely given removal of `.btn-xs`.
+- Removed explicit spacing between button groups in button toolbars; use margin utilities now.
+- Improved documentation for use with other components.
+
+### Dropdowns
+
+- Switched from parent selectors to singular classes for all components, modifiers, etc.
+- Simplified dropdown styles to no longer ship with upward or downward facing arrows attached to the dropdown menu.
+- Dropdowns can be built with `<div>`s or `<ul>`s now.
+- Rebuilt dropdown styles and markup to provide easy, built-in support for `<a>` and `<button>` based dropdown items.
+- Renamed `.divider` to `.dropdown-divider`.
+- Dropdown items now require `.dropdown-item`.
+- Dropdown toggles no longer require an explicit `<span class="caret"></span>`; this is now provided automatically via CSS's `::after` on `.dropdown-toggle`.
+
+### Grid system
+
+- Added a new `576px` grid breakpoint as `sm`, meaning there are now five total tiers (`xs`, `sm`, `md`, `lg`, and `xl`).
+- Renamed the responsive grid modifier classes from `.col-{breakpoint}-{modifier}-{size}` to `.{modifier}-{breakpoint}-{size}` for simpler grid classes.
+- Dropped push and pull modifier classes for the new flexbox-powered `order` classes. For example, instead of `.col-8.push-4` and `.col-4.pull-8`, you'd use `.col-8.order-2` and `.col-4.order-1`.
+- Added flexbox utility classes for grid system and components.
+
+### List groups
+
+- Rewrote component with flexbox.
+- Replaced `a.list-group-item` with an explicit class, `.list-group-item-action`, for styling link and button versions of list group items.
+- Added `.list-group-flush` class for use with cards.
+
+### Modal
+
+- Rewrote component with flexbox.
+- Given the move to flexbox, alignment of dismiss icons in the header is likely broken as we're no longer using floats. Floated content comes first, but with flexbox that's no longer the case. Update your dismiss icons to come after modal titles to fix.
+- The `remote` option (which could be used to automatically load and inject external content into a modal) and the corresponding `loaded.bs.modal` event were removed. We recommend instead using client-side templating or a data binding framework, or calling [jQuery.load](https://api.jquery.com/load/) yourself.
+
+### Navs
+
+- Rewrote component with flexbox.
+- Dropped nearly all `>` selectors for simpler styling via un-nested classes.
+- Instead of HTML-specific selectors like `.nav > li > a`, we use separate classes for `.nav`s, `.nav-item`s, and `.nav-link`s. This makes your HTML more flexible while bringing along increased extensibility.
+
+### Navbar
+
+The navbar has been entirely rewritten in flexbox with improved support for alignment, responsiveness, and customization.
+
+- Responsive navbar behaviors are now applied to the `.navbar` class via the **required** `.navbar-expand-{breakpoint}` where you choose where to collapse the navbar. Previously this was a Less variable modification and required recompiling.
+- `.navbar-default` is now `.navbar-light`, though `.navbar-dark` remains the same. **One of these is required on each navbar.** However, these classes no longer set `background-color`s; instead they essentially only affect `color`.
+- Navbars now require a background declaration of some kind. Choose from our background utilities (`.bg-*`) or set your own with the light/inverse classes above [for mad customization]({{< docsref "/components/navbar#color-schemes" >}}).
+- Given flexbox styles, navbars can now use flexbox utilities for easy alignment options.
+- `.navbar-toggle` is now `.navbar-toggler` and has different styles and inner markup (no more three `<span>`s).
+- Dropped the `.navbar-form` class entirely. It's no longer necessary; instead, just use `.form-inline` and apply margin utilities as necessary.
+- Navbars no longer include `margin-bottom` or `border-radius` by default. Use utilities as necessary.
+- All examples featuring navbars have been updated to include new markup.
+
+### Pagination
+
+- Rewrote component with flexbox.
+- Explicit classes (`.page-item`, `.page-link`) are now required on the descendants of `.pagination`s
+- Dropped the `.pager` component entirely as it was little more than customized outline buttons.
+
+### Breadcrumbs
+
+- An explicit class, `.breadcrumb-item`, is now required on the descendants of `.breadcrumb`s
+
+### Labels and badges
+
+- Consolidated `.label` and `.badge` to disambiguate from the `<label>` element and simplify related components.
+- Added `.badge-pill` as modifier for rounded "pill" look.
+- Badges are no longer floated automatically in list groups and other components. Utility classes are now required for that.
+- `.badge-default` has been dropped and `.badge-secondary` added to match component modifier classes used elsewhere.
+
+### Panels, thumbnails, and wells
+
+Dropped entirely for the new card component.
+
+### Panels
+
+- `.panel` to `.card`, now built with flexbox.
+- `.panel-default` removed and no replacement.
+- `.panel-group` removed and no replacement. `.card-group` is not a replacement, it is different.
+- `.panel-heading` to `.card-header`
+- `.panel-title` to `.card-title`. Depending on the desired look, you may also want to use [heading elements or classes]({{< docsref "/content/typography#headings" >}}) (e.g. `<h3>`, `.h3`) or bold elements or classes (e.g. `<strong>`, `<b>`, [`.font-weight-bold`]({{< docsref "/utilities/text#font-weight-and-italics" >}})). Note that `.card-title`, while similarly named, produces a different look than `.panel-title`.
+- `.panel-body` to `.card-body`
+- `.panel-footer` to `.card-footer`
+- `.panel-primary`, `.panel-success`, `.panel-info`, `.panel-warning`, and `.panel-danger` have been dropped for `.bg-`, `.text-`, and `.border` utilities generated from our `$theme-colors` Sass map.
+
+### Progress
+
+- Replaced contextual `.progress-bar-*` classes with `.bg-*` utilities. For example, `class="progress-bar progress-bar-danger"` becomes `class="progress-bar bg-danger"`.
+- Replaced `.active` for animated progress bars with `.progress-bar-animated`.
+
+### Carousel
+
+- Overhauled the entire component to simplify design and styling. We have fewer styles for you to override, new indicators, and new icons.
+- All CSS has been un-nested and renamed, ensuring each class is prefixed with `.carousel-`.
+  - For carousel items, `.next`, `.prev`, `.left`, and `.right` are now `.carousel-item-next`, `.carousel-item-prev`, `.carousel-item-left`, and `.carousel-item-right`.
+  - `.item` is also now `.carousel-item`.
+  - For prev/next controls, `.carousel-control.right` and `.carousel-control.left` are now `.carousel-control-next` and `.carousel-control-prev`, meaning they no longer require a specific base class.
+- Removed all responsive styling, deferring to utilities (e.g., showing captions on certain viewports) and custom styles as needed.
+- Removed image overrides for images in carousel items, deferring to utilities.
+- Tweaked the Carousel example to include the new markup and styles.
+
+### Tables
+
+- Removed support for styled nested tables. All table styles are now inherited in v4 for simpler selectors.
+- Added inverse table variant.
+
+### Utilities
+
+- **Display, hidden, and more:**
+  - Made display utilities responsive (e.g., `.d-none` and `d-{sm,md,lg,xl}-none`).
+  - Dropped the bulk of `.hidden-*` utilities for new [display utilities]({{< docsref "/utilities/display" >}}). For example, instead of `.hidden-sm-up`, use `.d-sm-none`. Renamed the `.hidden-print` utilities to use the display utility naming scheme. More info under the [Responsive utilities](#responsive-utilities) section of this page.
+  - Added `.float-{sm,md,lg,xl}-{left,right,none}` classes for responsive floats and removed `.pull-left` and `.pull-right` since they're redundant to `.float-left` and `.float-right`.
+- **Type:**
+  - Added responsive variations to our text alignment classes `.text-{sm,md,lg,xl}-{left,center,right}`.
+- **Alignment and spacing:**
+  - Added new [responsive margin and padding utilities]({{< docsref "/utilities/spacing" >}}) for all sides, plus vertical and horizontal shorthands.
+  - Added boatload of [flexbox utilities]({{< docsref "/utilities/flex" >}}).
+  - Dropped `.center-block` for the new `.mx-auto` class.
+- Clearfix updated to drop support for older browser versions.
+
+### Vendor prefix mixins
+
+Bootstrap 3's [vendor prefix](https://www.lifewire.com/css-vendor-prefixes-3466867) mixins, which were deprecated in v3.2.0, have been removed in Bootstrap 4. Since we use [Autoprefixer](https://github.com/postcss/autoprefixer), they're no longer necessary.
+
+Removed the following mixins: `animation`, `animation-delay`, `animation-direction`, `animation-duration`, `animation-fill-mode`, `animation-iteration-count`, `animation-name`, `animation-timing-function`, `backface-visibility`, `box-sizing`, `content-columns`, `hyphens`, `opacity`, `perspective`, `perspective-origin`, `rotate`, `rotateX`, `rotateY`, `scale`, `scaleX`, `scaleY`, `skew`, `transform-origin`, `transition-delay`, `transition-duration`, `transition-property`, `transition-timing-function`, `transition-transform`, `translate`, `translate3d`, `user-select`
+
+## Documentation
+
+Our documentation received an upgrade across the board as well. Here's the low down:
+
+- We're still using Jekyll, but we have plugins in the mix:
+  - `bugify.rb` is used to efficiently list out the entries on our [browser bugs]({{< docsref "/browser-bugs" >}}) page.
+  - `example.rb` is a custom fork of the default `highlight.rb` plugin, allowing for easier example-code handling.
+  - `callout.rb` is a similar custom fork of that, but designed for our special docs callouts.
+  - [jekyll-toc](https://github.com/toshimaru/jekyll-toc) is used to generate our table of contents.
+- All docs content has been rewritten in Markdown (instead of HTML) for easier editing.
+- Pages have been reorganized for simpler content and a more approachable hierarchy.
+- We moved from regular CSS to SCSS to take full advantage of Bootstrap's variables, mixins, and more.
+
+### Responsive utilities
+
+All `@screen-` variables have been removed in v4.0.0. Use the `media-breakpoint-up()`, `media-breakpoint-down()`, or `media-breakpoint-only()` Sass mixins or the `$grid-breakpoints` Sass map instead.
+
+Our responsive utility classes have largely been removed in favor of explicit `display` utilities.
+
+- The `.hidden` and `.show` classes have been removed because they conflicted with jQuery's `$(...).hide()` and `$(...).show()` methods. Instead, try toggling the `[hidden]` attribute or use inline styles like `style="display: none;"` and `style="display: block;"`.
+- All `.hidden-` classes have been removed, save for the print utilities which have been renamed.
+  - Removed from v3: `.hidden-xs` `.hidden-sm` `.hidden-md` `.hidden-lg` `.visible-xs-block` `.visible-xs-inline` `.visible-xs-inline-block` `.visible-sm-block` `.visible-sm-inline` `.visible-sm-inline-block` `.visible-md-block` `.visible-md-inline` `.visible-md-inline-block` `.visible-lg-block` `.visible-lg-inline` `.visible-lg-inline-block`
+  - Removed from v4 alphas: `.hidden-xs-up` `.hidden-xs-down` `.hidden-sm-up` `.hidden-sm-down` `.hidden-md-up` `.hidden-md-down` `.hidden-lg-up` `.hidden-lg-down`
+- Print utilities no longer start with `.hidden-` or `.visible-`, but with `.d-print-`.
+  - Old names: `.visible-print-block`, `.visible-print-inline`, `.visible-print-inline-block`, `.hidden-print`
+  - New classes: `.d-print-block`, `.d-print-inline`, `.d-print-inline-block`, `.d-print-none`
+
+Rather than using explicit `.visible-*` classes, you make an element visible by simply not hiding it at that screen size. You can combine one `.d-*-none` class with one `.d-*-block` class to show an element only on a given interval of screen sizes (e.g. `.d-none.d-md-block.d-xl-none` shows the element only on medium and large devices).
+
+Note that the changes to the grid breakpoints in v4 means that you'll need to go one breakpoint larger to achieve the same results. The new responsive utility classes don't attempt to accommodate less common cases where an element's visibility can't be expressed as a single contiguous range of viewport sizes; you will instead need to use custom CSS in such cases.

+Easily clear `float`s by adding `.clearfix` **to the parent element**. Can also be used as a mixin.
+
+```html
+<div class="clearfix">...</div>
+```
+
+```scss
+// Mixin itself

+## Background color
+
+Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes. Background utilities **do not set `color`**, so in some cases you'll want to use `.text-*` utilities.

+title: Display property
+description: Quickly and responsively toggle the display value of components and more with our display utilities. Includes support for some of the more common values, as well as some extras for controlling display when printing.
+group: utilities
+toc: true
+---
+
+## How it works
+
+Change the value of the [`display` property](https://developer.mozilla.org/en-US/docs/Web/CSS/display) with our responsive display utility classes. We purposely support only a subset of all possible values for `display`. Classes can be combined for various effects as you need.
+
+## Notation
+
+Display utility classes that apply to all [breakpoints]({{< docsref "/layout/overview#responsive-breakpoints" >}}), from `xs` to `xl`, have no breakpoint abbreviation in them. This is because those classes are applied from `min-width: 0;` and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.
+
+As such, the classes are named using the format:
+
+* `.d-{value}` for `xs`
+* `.d-{breakpoint}-{value}` for `sm`, `md`, `lg`, and `xl`.
+
+Where *value* is one of:
+
+* `none`
+* `inline`
+* `inline-block`
+* `block`
+* `table`
+* `table-cell`
+* `table-row`
+* `flex`
+* `inline-flex`
+
+The display values can be altered by changing the `$displays` variable and recompiling the SCSS.
+
+The media queries affect screen widths with the given breakpoint *or larger*. For example, `.d-lg-none` sets `display: none;` on both `lg` and `xl` screens.
+
+## Examples
+
+{{< example >}}
+<div class="d-inline p-2 bg-primary text-white">d-inline</div>
+<div class="d-inline p-2 bg-dark text-white">d-inline</div>
+{{< /example >}}
+
+{{< example >}}
+<span class="d-block p-2 bg-primary text-white">d-block</span>
+<span class="d-block p-2 bg-dark text-white">d-block</span>
+{{< /example >}}
+
+## Hiding elements
+
+For faster mobile-friendly development, use responsive display classes for showing and hiding elements by device. Avoid creating entirely different versions of the same site, instead hide elements responsively for each screen size.
+
+To hide elements simply use the `.d-none` class or one of the `.d-{sm,md,lg,xl}-none` classes for any responsive screen variation.
+
+To show an element only on a given interval of screen sizes you can combine one `.d-*-none` class with a `.d-*-*` class, for example `.d-none .d-md-block .d-xl-none` will hide the element for all screen sizes except on medium and large devices.
+
+| Screen Size        | Class |
+| ---                | --- |
+| Hidden on all      | `.d-none` |
+| Hidden only on xs  | `.d-none .d-sm-block` |
+| Hidden only on sm  | `.d-sm-none .d-md-block` |
+| Hidden only on md  | `.d-md-none .d-lg-block` |
+| Hidden only on lg  | `.d-lg-none .d-xl-block` |
+| Hidden only on xl  | `.d-xl-none` |
+| Visible on all     | `.d-block` |
+| Visible only on xs | `.d-block .d-sm-none` |
+| Visible only on sm | `.d-none .d-sm-block .d-md-none` |
+| Visible only on md | `.d-none .d-md-block .d-lg-none` |
+| Visible only on lg | `.d-none .d-lg-block .d-xl-none` |
+| Visible only on xl | `.d-none .d-xl-block` |
+
+{{< example >}}
+<div class="d-lg-none">hide on lg and wider screens</div>
+<div class="d-none d-lg-block">hide on screens smaller than lg</div>
+{{< /example >}}
+
+## Display in print
+
+Change the `display` value of elements when printing with our print display utility classes. Includes support for the same `display` values as our responsive `.d-*` utilities.
+
+- `.d-print-none`
+- `.d-print-inline`
+- `.d-print-inline-block`
+- `.d-print-block`
+- `.d-print-table`
+- `.d-print-table-row`
+- `.d-print-table-cell`
+- `.d-print-flex`
+- `.d-print-inline-flex`
+
+The print and display classes can be combined.
+

+title: Embeds
+description: Create responsive video or slideshow embeds based on the width of the parent by creating an intrinsic ratio that scales on any device.
+group: utilities
+toc: true
+---
+
+## About
+
+Rules are directly applied to `<iframe>`, `<embed>`, `<video>`, and `<object>` elements; optionally use an explicit descendant class `.embed-responsive-item` when you want to match the styling for other attributes.
+
+**Pro-Tip!** You don't need to include `frameborder="0"` in your `<iframe>`s as we override that for you.
+
+## Example
+
+Wrap any embed like an `<iframe>` in a parent element with `.embed-responsive` and an aspect ratio. The `.embed-responsive-item` isn't strictly required, but we encourage it.
+
+{{< example >}}
+<div class="embed-responsive embed-responsive-16by9">
+  <iframe class="embed-responsive-item" src="https://www.youtube.com/embed/zpOULjyy-n8?rel=0" allowfullscreen></iframe>
+</div>
+{{< /example >}}
+
+## Aspect ratios
+
+Aspect ratios can be customized with modifier classes. By default the following ratio classes are provided:
+
+```html
+<!-- 21:9 aspect ratio -->
+<div class="embed-responsive embed-responsive-21by9">
+  <iframe class="embed-responsive-item" src="..."></iframe>
+</div>
+
+<!-- 16:9 aspect ratio -->
+<div class="embed-responsive embed-responsive-16by9">
+  <iframe class="embed-responsive-item" src="..."></iframe>
+</div>
+
+<!-- 4:3 aspect ratio -->
+<div class="embed-responsive embed-responsive-4by3">
+  <iframe class="embed-responsive-item" src="..."></iframe>
+</div>
+
+<!-- 1:1 aspect ratio -->
+<div class="embed-responsive embed-responsive-1by1">
+  <iframe class="embed-responsive-item" src="..."></iframe>
+</div>
+```
+
+Within `_variables.scss`, you can change the aspect ratios you want to use. Here's an example of the `$embed-responsive-aspect-ratios` list:
+
+```scss
+$embed-responsive-aspect-ratios: (
+  (21 9),
+  (16 9),
+  (4 3),
+  (1 1)
+) !default;
+```

+title: Flex
+description: Quickly manage the layout, alignment, and sizing of grid columns, navigation, components, and more with a full suite of responsive flexbox utilities. For more complex implementations, custom CSS may be necessary.
+group: utilities
+toc: true
+---
+
+## Enable flex behaviors
+
+Apply `display` utilities to create a flexbox container and transform **direct children elements** into flex items. Flex containers and items are able to be modified further with additional flex properties.
+
+{{< example >}}
+<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div>
+{{< /example >}}
+
+{{< example >}}
+<div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>
+{{< /example >}}
+
+Responsive variations also exist for `.d-flex` and `.d-inline-flex`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.d{{ .abbr }}-flex`
+- `.d{{ .abbr }}-inline-flex`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Direction
+
+Set the direction of flex items in a flex container with direction utilities. In most cases you can omit the horizontal class here as the browser default is `row`. However, you may encounter situations where you needed to explicitly set this value (like responsive layouts).
+
+Use `.flex-row` to set a horizontal direction (the browser default), or `.flex-row-reverse` to start the horizontal direction from the opposite side.
+
+{{< example >}}
+<div class="d-flex flex-row bd-highlight mb-3">
+  <div class="p-2 bd-highlight">Flex item 1</div>
+  <div class="p-2 bd-highlight">Flex item 2</div>
+  <div class="p-2 bd-highlight">Flex item 3</div>
+</div>
+<div class="d-flex flex-row-reverse bd-highlight">
+  <div class="p-2 bd-highlight">Flex item 1</div>
+  <div class="p-2 bd-highlight">Flex item 2</div>
+  <div class="p-2 bd-highlight">Flex item 3</div>
+</div>
+{{< /example >}}
+
+Use `.flex-column` to set a vertical direction, or `.flex-column-reverse`  to start the vertical direction from the opposite side.
+
+{{< example >}}
+<div class="d-flex flex-column bd-highlight mb-3">
+  <div class="p-2 bd-highlight">Flex item 1</div>
+  <div class="p-2 bd-highlight">Flex item 2</div>
+  <div class="p-2 bd-highlight">Flex item 3</div>
+</div>
+<div class="d-flex flex-column-reverse bd-highlight">
+  <div class="p-2 bd-highlight">Flex item 1</div>
+  <div class="p-2 bd-highlight">Flex item 2</div>
+  <div class="p-2 bd-highlight">Flex item 3</div>
+</div>
+{{< /example >}}
+
+Responsive variations also exist for `flex-direction`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.flex{{ .abbr }}-row`
+- `.flex{{ .abbr }}-row-reverse`
+- `.flex{{ .abbr }}-column`
+- `.flex{{ .abbr }}-column-reverse`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Justify content
+
+Use `justify-content` utilities on flexbox containers to change the alignment of flex items on the main axis (the x-axis to start, y-axis if `flex-direction: column`). Choose from `start` (browser default), `end`, `center`, `between`, or `around`.
+
+<div class="bd-example">
+  <div class="d-flex justify-content-start bd-highlight mb-3">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex justify-content-end bd-highlight mb-3">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex justify-content-center bd-highlight mb-3">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex justify-content-between bd-highlight mb-3">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex justify-content-around bd-highlight">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+</div>
+
+```html
+<div class="d-flex justify-content-start">...</div>
+<div class="d-flex justify-content-end">...</div>
+<div class="d-flex justify-content-center">...</div>
+<div class="d-flex justify-content-between">...</div>
+<div class="d-flex justify-content-around">...</div>
+```
+
+Responsive variations also exist for `justify-content`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.justify-content{{ .abbr }}-start`
+- `.justify-content{{ .abbr }}-end`
+- `.justify-content{{ .abbr }}-center`
+- `.justify-content{{ .abbr }}-between`
+- `.justify-content{{ .abbr }}-around`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Align items
+
+Use `align-items` utilities on flexbox containers to change the alignment of flex items on the cross axis (the y-axis to start, x-axis if `flex-direction: column`). Choose from `start`, `end`, `center`, `baseline`, or `stretch` (browser default).
+
+<div class="bd-example">
+  <div class="d-flex align-items-start bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex align-items-end bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex align-items-center bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex align-items-baseline bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex align-items-stretch bd-highlight" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+</div>
+
+```html
+<div class="d-flex align-items-start">...</div>
+<div class="d-flex align-items-end">...</div>
+<div class="d-flex align-items-center">...</div>
+<div class="d-flex align-items-baseline">...</div>
+<div class="d-flex align-items-stretch">...</div>
+```
+
+Responsive variations also exist for `align-items`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.align-items{{ .abbr }}-start`
+- `.align-items{{ .abbr }}-end`
+- `.align-items{{ .abbr }}-center`
+- `.align-items{{ .abbr }}-baseline`
+- `.align-items{{ .abbr }}-stretch`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Align self
+
+Use `align-self` utilities on flexbox items to individually change their alignment on the cross axis (the y-axis to start, x-axis if `flex-direction: column`). Choose from the same options as `align-items`: `start`, `end`, `center`, `baseline`, or `stretch` (browser default).
+
+<div class="bd-example">
+  <div class="d-flex bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="align-self-start p-2 bd-highlight">Aligned flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="align-self-end p-2 bd-highlight">Aligned flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="align-self-center p-2 bd-highlight">Aligned flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex bd-highlight mb-3" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="align-self-baseline p-2 bd-highlight">Aligned flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+  <div class="d-flex bd-highlight" style="height: 100px">
+    <div class="p-2 bd-highlight">Flex item</div>
+    <div class="align-self-stretch p-2 bd-highlight">Aligned flex item</div>
+    <div class="p-2 bd-highlight">Flex item</div>
+  </div>
+</div>
+
+```html
+<div class="align-self-start">Aligned flex item</div>
+<div class="align-self-end">Aligned flex item</div>
+<div class="align-self-center">Aligned flex item</div>
+<div class="align-self-baseline">Aligned flex item</div>
+<div class="align-self-stretch">Aligned flex item</div>
+```
+
+Responsive variations also exist for `align-self`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.align-self{{ .abbr }}-start`
+- `.align-self{{ .abbr }}-end`
+- `.align-self{{ .abbr }}-center`
+- `.align-self{{ .abbr }}-baseline`
+- `.align-self{{ .abbr }}-stretch`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Fill
+
+Use the `.flex-fill` class on a series of sibling elements to force them into widths equal to their content (or equal widths if their content does not surpass their border-boxes) while taking up all available horizontal space.
+
+{{< example >}}
+<div class="d-flex bd-highlight">
+  <div class="p-2 flex-fill bd-highlight">Flex item with a lot of content</div>
+  <div class="p-2 flex-fill bd-highlight">Flex item</div>
+  <div class="p-2 flex-fill bd-highlight">Flex item</div>
+</div>
+{{< /example >}}
+
+Responsive variations also exist for `flex-fill`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.flex{{ .abbr }}-fill`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Grow and shrink
+
+Use `.flex-grow-*` utilities to toggle a flex item's ability to grow to fill available space. In the example below, the `.flex-grow-1` elements uses all available space it can, while allowing the remaining two flex items their necessary space.
+
+{{< example >}}
+<div class="d-flex bd-highlight">
+  <div class="p-2 flex-grow-1 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Third flex item</div>
+</div>
+{{< /example >}}
+
+Use `.flex-shrink-*` utilities to toggle a flex item's ability to shrink if necessary. In the example below, the second flex item with `.flex-shrink-1` is forced to wrap its contents to a new line, "shrinking" to allow more space for the previous flex item with `.w-100`.
+
+{{< example >}}
+<div class="d-flex bd-highlight">
+  <div class="p-2 w-100 bd-highlight">Flex item</div>
+  <div class="p-2 flex-shrink-1 bd-highlight">Flex item</div>
+</div>
+{{< /example >}}
+
+Responsive variations also exist for `flex-grow` and `flex-shrink`.
+
+{{< markdown >}}
+{{< flex.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.flex{{ .abbr }}-{grow|shrink}-0`
+- `.flex{{ .abbr }}-{grow|shrink}-1`
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+## Auto margins
+
+Flexbox can do some pretty awesome things when you mix flex alignments with auto margins. Shown below are three examples of controlling flex items via auto margins: default (no auto margin), pushing two items to the right (`.mr-auto`), and pushing two items to the left (`.ml-auto`).
+
+**Unfortunately, IE10 and IE11 do not properly support auto margins on flex items whose parent has a non-default `justify-content` value.** [See this StackOverflow answer](https://stackoverflow.com/a/37535548) for more details.
+
+{{< example >}}
+<div class="d-flex bd-highlight mb-3">
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+</div>
+
+<div class="d-flex bd-highlight mb-3">
+  <div class="mr-auto p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+</div>
+
+<div class="d-flex bd-highlight mb-3">
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="ml-auto p-2 bd-highlight">Flex item</div>
+</div>
+{{< /example >}}
+
+### With align-items
+
+Vertically move one flex item to the top or bottom of a container by mixing `align-items`, `flex-direction: column`, and `margin-top: auto` or `margin-bottom: auto`.
+
+{{< example >}}
+<div class="d-flex align-items-start flex-column bd-highlight mb-3" style="height: 200px;">
+  <div class="mb-auto p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+</div>
+
+<div class="d-flex align-items-end flex-column bd-highlight mb-3" style="height: 200px;">
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="p-2 bd-highlight">Flex item</div>
+  <div class="mt-auto p-2 bd-highlight">Flex item</div>
+</div>
+{{< /example >}}
+
+## Wrap
+
+Change how flex items wrap in a flex container. Choose from no wrapping at all (the browser default) with `.flex-nowrap`, wrapping with `.flex-wrap`, or reverse wrapping with `.flex-wrap-reverse`.
+
+<div class="bd-example">
+  <div class="d-flex flex-nowrap bd-highlight" style="width: 8rem;">
+    <div class="p-2 bd-highlight">Flex item</div>

+{{< /markdown >}}
+
+## Order
+
+Change the _visual_ order of specific flex items with a handful of `order` utilities. We only provide options for making an item first or last, as well as a reset to use the DOM order. As `order` takes any integer value (e.g., `5`), add custom CSS for any additional values needed.
+
+{{< example >}}
+<div class="d-flex flex-nowrap bd-highlight">
+  <div class="order-3 p-2 bd-highlight">First flex item</div>
+  <div class="order-2 p-2 bd-highlight">Second flex item</div>
+  <div class="order-1 p-2 bd-highlight">Third flex item</div>

+- `.order{{ $bp.abbr }}-{{ . }}`
+{{- end -}}
+{{- end -}}
+{{< /flex.inline >}}
+{{< /markdown >}}
+
+
+## Align content
+
+Use `align-content` utilities on flexbox containers to align flex items *together* on the cross axis. Choose from `start` (browser default), `end`, `center`, `between`, `around`, or `stretch`. To demonstrate these utilities, we've enforced `flex-wrap: wrap` and increased the number of flex items.
+
+**Heads up!** This property has no effect on single rows of flex items.
+
+<div class="bd-example">
+  <div class="d-flex align-content-start flex-wrap bd-highlight mb-3" style="height: 200px">

+title: Float
+description: Toggle floats on any element, across any breakpoint, using our responsive float utilities.
+group: utilities
+toc: true
+---
+
+## Overview
+
+These utility classes float an element to the left or right, or disable floating, based on the current viewport size using the [CSS `float` property](https://developer.mozilla.org/en-US/docs/Web/CSS/float). `!important` is included to avoid specificity issues. These use the same viewport breakpoints as our grid system. Please be aware float utilities have no effect on flex items.
+
+## Classes
+
+Toggle a float with a class:
+
+{{< example >}}
+<div class="float-left">Float left on all viewport sizes</div><br>
+<div class="float-right">Float right on all viewport sizes</div><br>
+<div class="float-none">Don't float on all viewport sizes</div>
+{{< /example >}}
+
+## Mixins
+
+Or by Sass mixin:
+
+```scss
+.element {
+  @include float-left;
+}
+.another-element {
+  @include float-right;
+}
+.one-more {
+  @include float-none;
+}
+```
+
+## Responsive
+
+Responsive variations also exist for each `float` value.
+
+{{< example >}}
+<div class="float-sm-left">Float left on viewports sized SM (small) or wider</div><br>
+<div class="float-md-left">Float left on viewports sized MD (medium) or wider</div><br>
+<div class="float-lg-left">Float left on viewports sized LG (large) or wider</div><br>
+<div class="float-xl-left">Float left on viewports sized XL (extra-large) or wider</div><br>
+{{< /example >}}
+
+Here are all the support classes;
+
+{{< markdown >}}
+{{< float.inline >}}
+{{- range $.Site.Data.breakpoints }}
+- `.float{{ .abbr }}-left`
+- `.float{{ .abbr }}-right`

+## Sticky top
+
+Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The `.sticky-top` utility uses CSS's `position: sticky`, which isn't fully supported in all browsers.
+
+**IE11 and IE10 will render `position: sticky` as `position: relative`.** As such, we wrap the styles in a `@supports` query, limiting the stickiness to only browsers that can render it properly.

+layout: docs
+title: Spacing
+description: Bootstrap includes a wide range of shorthand responsive margin and padding utility classes to modify an element's appearance.
+group: utilities
+toc: true
+---
+
+## How it works
+
+Assign responsive-friendly `margin` or `padding` values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from `.25rem` to `3rem`.
+
+## Notation
+
+Spacing utilities that apply to all breakpoints, from `xs` to `xl`, have no breakpoint abbreviation in them. This is because those classes are applied from `min-width: 0` and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.
+
+The classes are named using the format `{property}{sides}-{size}` for `xs` and `{property}{sides}-{breakpoint}-{size}` for `sm`, `md`, `lg`, and `xl`.
+
+Where *property* is one of:
+
+* `m` - for classes that set `margin`
+* `p` - for classes that set `padding`
+
+Where *sides* is one of:
+
+* `t` - for classes that set `margin-top` or `padding-top`
+* `b` - for classes that set `margin-bottom` or `padding-bottom`
+* `l` - for classes that set `margin-left` or `padding-left`
+* `r` - for classes that set `margin-right` or `padding-right`
+* `x` - for classes that set both `*-left` and `*-right`
+* `y` - for classes that set both `*-top` and `*-bottom`
+* blank - for classes that set a `margin` or `padding` on all 4 sides of the element
+
+Where *size* is one of:
+
+* `0` - for classes that eliminate the `margin` or `padding` by setting it to `0`
+* `1` - (by default) for classes that set the `margin` or `padding` to `$spacer * .25`
+* `2` - (by default) for classes that set the `margin` or `padding` to `$spacer * .5`
+* `3` - (by default) for classes that set the `margin` or `padding` to `$spacer`
+* `4` - (by default) for classes that set the `margin` or `padding` to `$spacer * 1.5`
+* `5` - (by default) for classes that set the `margin` or `padding` to `$spacer * 3`
+* `auto` - for classes that set the `margin` to auto
+
+(You can add more sizes by adding entries to the `$spacers` Sass map variable.)
+
+## Examples
+
+Here are some representative examples of these classes:
+
+```scss
+.mt-0 {
+  margin-top: 0 !important;
+}
+
+.ml-1 {
+  margin-left: ($spacer * .25) !important;
+}
+
+.px-2 {
+  padding-left: ($spacer * .5) !important;
+  padding-right: ($spacer * .5) !important;
+}
+
+.p-3 {
+  padding: $spacer !important;
+}
+```
+
+### Horizontal centering
+
+Additionally, Bootstrap also includes an `.mx-auto` class for horizontally centering fixed-width block level content—that is, content that has `display: block` and a `width` set—by setting the horizontal margins to `auto`.
+
+<div class="bd-example">
+  <div class="mx-auto" style="width: 200px; background-color: rgba(86,61,124,.15);">
+    Centered element
+  </div>
+</div>
+
+```html
+<div class="mx-auto" style="width: 200px;">
+  Centered element
+</div>
+```
+
+### Negative margin
+
+In CSS, `margin` properties can utilize negative values (`padding` cannot). As of 4.2, we've added negative margin utilities for every non-zero integer size listed above (e.g., `1`, `2`, `3`, `4`, `5`). These utilities are ideal for customizing grid column gutters across breakpoints.
+
+The syntax is nearly the same as the default, positive margin utilities, but with the addition of `n` before the requested size. Here's an example class that's the opposite of `.mt-1`:

+title: Stretched link
+description: Make any HTML element or Bootstrap component clickable by "stretching" a nested link via CSS.
+group: utilities
+---
+
+Add `.stretched-link` to a link to make its [containing block](https://developer.mozilla.org/en-US/docs/Web/CSS/Containing_block) clickable via a `::after` pseudo element. In most cases, this means that an element with `position: relative;` that contains a link with the `.stretched-link` class is clickable. Please note given [how CSS `position` works](https://www.w3.org/TR/CSS21/visuren.html#propdef-position), `.stretched-link` cannot be mixed with most table elements.
+
+Cards have `position: relative` by default in Bootstrap, so in this case you can safely add the `.stretched-link` class to a link in the card without any other HTML changes.
+
+Multiple links and tap targets are not recommended with stretched links. However, some `position` and `z-index` styles can help should this be required.
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  {{< placeholder width="100%" height="180" class="card-img-top" text=" " title="Card image cap" >}}
+  <div class="card-body">
+    <h5 class="card-title">Card with stretched link</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+    <a href="#" class="btn btn-primary stretched-link">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+Media objects do not have `position: relative` by default, so we need to add the `.position-relative` here to prevent the link from stretching outside the media object.
+
+{{< example >}}
+<div class="media position-relative">
+  {{< placeholder width="144" height="144" class="mr-3" text=" " title="Generic placeholder image" >}}
+  <div class="media-body">
+    <h5 class="mt-0">Media with stretched link</h5>
+    <p>This is some placeholder content for the media object. It is intended to mimic what some real-world content would look like, and we're using it here to give the component a bit of body and size.</p>
+    <a href="#" class="stretched-link">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+Columns are `position: relative` by default, so clickable columns only require the `.stretched-link` class on a link. However, stretching a link over an entire `.row` requires `.position-static` on the column and `.position-relative` on the row.
+
+{{< example >}}
+<div class="row no-gutters bg-light position-relative">
+  <div class="col-md-6 mb-md-0 p-md-4">
+    {{< placeholder width="100%" height="200" class="w-100" text=" " title="Generic placeholder image" >}}
+  </div>
+  <div class="col-md-6 position-static p-4 pl-md-0">
+    <h5 class="mt-0">Columns with stretched link</h5>
+    <p>Another instance of placeholder content for this other custom component. It is intended to mimic what some real-world content would look like, and we're using it here to give the component a bit of body and size.</p>
+    <a href="#" class="stretched-link">Go somewhere</a>
+  </div>
+</div>
+{{< /example >}}
+
+## Identifying the containing block
+
+If the stretched link doesn't seem to work, the [containing block](https://developer.mozilla.org/en-US/docs/Web/CSS/Containing_block#Identifying_the_containing_block) will probably be the cause. The following CSS properties will make an element the containing block:
+
+- A `position` value other than `static`
+- A `transform` or `perspective` value other than `none`
+- A `will-change` value of `transform` or `perspective`
+- A `filter` value other than `none` or a `will-change` value of `filter` (only works on Firefox)
+
+{{< example >}}
+<div class="card" style="width: 18rem;">
+  {{< placeholder width="100%" height="180" class="card-img-top" text=" " title="Card image cap" >}}
+  <div class="card-body">
+    <h5 class="card-title">Card with stretched links</h5>
+    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
+    <p class="card-text">
+      <a href="#" class="stretched-link text-danger" style="position: relative;">Stretched link will not work here, because <code>position: relative</code> is added to the link</a>
+    </p>
+    <p class="card-text bg-light" style="transform: rotate(0);">
+      This <a href="#" class="text-warning stretched-link">stretched link</a> will only be spread over the <code>p</code>-tag, because a transform is applied to it.
+    </p>
+  </div>
+</div>

+title: Text
+description: Documentation and examples for common text utilities to control alignment, wrapping, weight, and more.
+group: utilities
+toc: true
+---
+
+## Text alignment
+
+Easily realign text to components with text alignment classes.
+
+{{< example >}}
+<p class="text-justify">Some placeholder text to demonstrate justified text alignment. Will you do the same for me? It's time to face the music I'm no longer your muse. Heard it's beautiful, be the judge and my girls gonna take a vote. I can feel a phoenix inside of me. Heaven is jealous of our love, angels are crying from up above. Yeah, you take me to utopia.</p>
+{{< /example >}}
+
+For left, right, and center alignment, responsive classes are available that use the same viewport width breakpoints as the grid system.
+
+{{< example >}}
+<p class="text-left">Left aligned text on all viewport sizes.</p>
+<p class="text-center">Center aligned text on all viewport sizes.</p>
+<p class="text-right">Right aligned text on all viewport sizes.</p>
+
+<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
+<p class="text-md-left">Left aligned text on viewports sized MD (medium) or wider.</p>
+<p class="text-lg-left">Left aligned text on viewports sized LG (large) or wider.</p>
+<p class="text-xl-left">Left aligned text on viewports sized XL (extra-large) or wider.</p>
+{{< /example >}}
+
+## Text wrapping and overflow
+
+Wrap text with a `.text-wrap` class.
+
+{{< example >}}
+<div class="badge badge-primary text-wrap" style="width: 6rem;">
+  This text should wrap.
+</div>
+{{< /example >}}
+
+Prevent text from wrapping with a `.text-nowrap` class.
+
+{{< example >}}
+<div class="text-nowrap bd-highlight" style="width: 8rem;">
+  This text should overflow the parent.
+</div>
+{{< /example >}}
+
+For longer content, you can add a `.text-truncate` class to truncate the text with an ellipsis. **Requires `display: inline-block` or `display: block`.**
+
+{{< example >}}
+<!-- Block level -->
+<div class="row">
+  <div class="col-2 text-truncate">
+    Praeterea iter est quasdam res quas ex communi.
+  </div>
+</div>
+
+<!-- Inline level -->
+<span class="d-inline-block text-truncate" style="max-width: 150px;">
+  Praeterea iter est quasdam res quas ex communi.
+</span>
+{{< /example >}}
+
+## Word break
+
+Prevent long strings of text from breaking your components' layout by using `.text-break` to set `word-wrap: break-word` and `word-break: break-word`. We use `word-wrap` instead of the more common `overflow-wrap` for wider browser support, and add the deprecated `word-break: break-word` to avoid issues with flex containers.
+
+{{< example >}}
+<p class="text-break">mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm</p>
+{{< /example >}}
+
+## Text transform
+
+Transform text in components with text capitalization classes.
+
+{{< example >}}
+<p class="text-lowercase">Lowercased text.</p>
+<p class="text-uppercase">Uppercased text.</p>
+<p class="text-capitalize">CapiTaliZed text.</p>
+{{< /example >}}
+
+Note how `.text-capitalize` only changes the first letter of each word, leaving the case of any other letters unaffected.
+
+## Font weight and italics
+
+Quickly change the weight (boldness) of text or italicize text.
+
+{{< example >}}
+<p class="font-weight-bold">Bold text.</p>
+<p class="font-weight-bolder">Bolder weight text (relative to the parent element).</p>
+<p class="font-weight-normal">Normal weight text.</p>
+<p class="font-weight-light">Light weight text.</p>
+<p class="font-weight-lighter">Lighter weight text (relative to the parent element).</p>
+<p class="font-italic">Italic text.</p>
+{{< /example >}}
+
+## Monospace
+
+Change a selection to our monospace font stack with `.text-monospace`.
+
+{{< example >}}
+<p class="text-monospace">This is in monospace</p>
+{{< /example >}}
+
+## Reset color
+
+Reset a text or link's color with `.text-reset`, so that it inherits the color from its parent.
+
+{{< example >}}
+<p class="text-muted">
+  Muted text with a <a href="#" class="text-reset">reset link</a>.
+</p>
+{{< /example >}}
+
+## Text decoration
+
+Remove a text decoration with a `.text-decoration-none` class.
+
+{{< example >}}
+<a href="#" class="text-decoration-none">Non-underlined link</a>
+{{< /example >}}

+Change the alignment of elements with the [`vertical-alignment`](https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align) utilities. Please note that vertical-align only affects inline, inline-block, inline-table, and table cell elements.
+
+Choose from `.align-baseline`, `.align-top`, `.align-middle`, `.align-bottom`, `.align-text-bottom`, and `.align-text-top` as needed.
+
+With inline elements:
+
+{{< example >}}
+<span class="align-baseline">baseline</span>
+<span class="align-top">top</span>
+<span class="align-middle">middle</span>
+<span class="align-bottom">bottom</span>
+<span class="align-text-top">text-top</span>
+<span class="align-text-bottom">text-bottom</span>
+{{< /example >}}
+
+With table cells:
+
+{{< example >}}
+<table style="height: 100px;">
+  <tbody>
+    <tr>
+      <td class="align-baseline">baseline</td>
+      <td class="align-top">top</td>
+      <td class="align-middle">middle</td>
+      <td class="align-bottom">bottom</td>
+      <td class="align-text-top">text-top</td>
+      <td class="align-text-bottom">text-bottom</td>
+    </tr>

Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the `.sr-only` class.
