-      <h2>Mixed: mobile and desktop</h2>
-      <p>The Bootstrap v4 grid system has five tiers of classes: xs (extra small), 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 xs and sm, you only need to specify xs.</p>

-            <p>This example is a quick exercise to illustrate how the navbar and its contents work. Some navbars extend the width of the viewport, others are confined within a <code>.container</code>. For positioning of navbars, checkout the <a href="../navbar-static/">top</a> and <a href="../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>

 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/2010/hack-week) 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]({{ site.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.

+## 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.

They're toggled by clicking, not by hovering; this is [an intentional design decision](http://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/).
 
 Dropdowns are built on a third party library, [Popper.js](https://popper.js.org/), which provides dynamic positioning and viewport detection. Be sure to include [popper.min.js]({{ site.cdn.popper }}) before Bootstrap's JavaScript or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js. Popper.js isn't used to position dropdowns in navbars though as dynamic positioning isn't required.

 ## 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 is wrapped in a `<div>` with a sibling `<span>` to create our custom control and a `<label>` for the accompanying text. Structurally, this is the same approach as our default `.form-check`.
+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.

+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):
+
+{% capture 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>

+## 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`.
+
+{% capture example %}
+<div class="input-group flex-nowrap">
+  <div class="input-group-prepend">

 ## 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.

+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>`.
+
+## Border spinner
+
+Use the border spinners for a lightweight loading indicator.
+
+{% capture example %}
+<div class="spinner-border" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{% endcapture %}
+{% include example.html content=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.
+
+{% capture example %}
+{% for color in site.data.theme-colors %}
+<div class="spinner-border text-{{ color.name }}" role="status">
+  <span class="sr-only">Loading...</span>
+</div>{% endfor %}
+{% endcapture %}
+{% include example.html content=example %}
+
+{% capture callout %}
+**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.
+{% endcapture %}
+{% include callout.html content=callout type="info" %}
+
+## 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!
+
+{% capture example %}
+<div class="spinner-grow" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{% endcapture %}
+{% include example.html content=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.
+
+{% capture example %}
+{% for color in site.data.theme-colors %}
+<div class="spinner-grow text-{{ color.name }}" role="status">
+  <span class="sr-only">Loading...</span>
+</div>{% endfor %}
+{% endcapture %}
+{% include example.html content=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.
+
+{% capture example %}
+<div class="spinner-border m-5" role="status">
+  <span class="sr-only">Loading...</span>
+</div>
+{% endcapture %}
+{% include example.html content=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
+
+{% capture example %}
+<div class="d-flex justify-content-center">
+  <div class="spinner-border" role="status">
+    <span class="sr-only">Loading...</span>
+  </div>
+</div>
+{% endcapture %}
+{% include example.html content=example %}
+
+{% capture example %}
+<div class="d-flex align-items-center">
+  <strong>Loading...</strong>
+  <div class="spinner-border ml-auto" role="status" aria-hidden="true"></div>
+</div>
+{% endcapture %}
+{% include example.html content=example %}
+
+#### Floats
+
+{% capture example %}
+<div class="clearfix">
+  <div class="spinner-border float-right" role="status">
+    <span class="sr-only">Loading...</span>
+  </div>
+</div>
+{% endcapture %}
+{% include example.html content=example %}
+
+#### Text align
+
+{% capture example %}
+<div class="text-center">
+  <div class="spinner-border" role="status">
+    <span class="sr-only">Loading...</span>
+  </div>
+</div>
+{% endcapture %}
+{% include example.html content=example %}
+
+## Size
+
+Add `.spinner-border-sm` and `.spinner-grow-sm` to make a smaller spinner that can quickly be used within other components.
+
+{% capture 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>
+{% endcapture %}
+{% include example.html content=example %}
+
+Or, use custom CSS or inline styles to change the dimensions as needed.
+
+{% capture 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>
+{% endcapture %}
+{% include example.html content=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.
+
+{% capture 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>
+{% endcapture %}
+{% include example.html content=example %}
+
+{% capture 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>
+{% endcapture %}

+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`]({{ site.baseurl }}/docs/{{ site.docs_version }}/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`.
+
+## 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.
+
+{% capture example %}
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {% include icons/placeholder.svg 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>
+{% endcapture %}
+{% include example.html content=example class="bg-light" %}
+
+### 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.
+
+{% capture example %}
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {% include icons/placeholder.svg 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>
+{% endcapture %}
+{% include example.html content=example class="bg-dark" %}
+
+### Stacking
+
+When you have multiple toasts, we default to vertically stacking them in a readable manner.
+
+{% capture example %}
+<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+  <div class="toast-header">
+    {% include icons/placeholder.svg 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">
+    {% include icons/placeholder.svg 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>
+{% endcapture %}
+{% include example.html content=example class="bg-light" %}
+
+## 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`.
+
+{% capture example %}
+<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">
+      {% include icons/placeholder.svg 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>
+</div>
+{% endcapture %}
+{% include example.html content=example class="bg-dark" %}
+
+For systems that generate more notifications, consider using a wrapping element so they can easily stack.
+
+{% capture example %}
+<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
+  <!-- Position it -->
+  <div style="position: absolute; top: 0; right: 0;">
+
+    <!-- Then put toasts within -->
+    <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+      <div class="toast-header">
+        {% include icons/placeholder.svg 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">
+        {% include icons/placeholder.svg 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>
+  </div>
+</div>
+{% endcapture %}
+{% include example.html content=example class="bg-dark" %}
+
+You can also get fancy with flexbox utilities to align toasts horizontally and/or vertically.
+
+{% capture example %}
+<!-- Flexbox container for aligning the toasts -->
+<div aria-live="polite" aria-atomic="true" class="d-flex justify-content-center align-items-center" style="min-height: 200px;">
+
+  <!-- Then put toasts within -->
+  <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
+    <div class="toast-header">
+      {% include icons/placeholder.svg 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>
+</div>
+{% endcapture %}
+{% include example.html content=example class="bg-dark" %}
+
+## 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]({{ site.baseurl }}/docs/{{ site.docs_version }}/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.
+
+{% highlight 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>
+{% endhighlight %}
+
+When using `autohide: false`, you must add a close button to allow users to dismiss the toast.
+
+{% capture example %}
+<div role="alert" aria-live="assertive" aria-atomic="true" class="toast" data-autohide="false">
+  <div class="toast-header">
+    {% include icons/placeholder.svg 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>
+{% endcapture %}
+{% include example.html content=example class="bg-light" %}
+
+## JavaScript behavior
+
+### Usage
+
+Initialize toasts via JavaScript:
+
+{% highlight js %}
+$('.toast').toast(option)
+{% endhighlight %}
+
+### 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.

+#### `.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`.
+

-## Responsive typography
-
-*Responsive typography* refers to scaling text and components by simply adjusting the root element's `font-size` within a series of media queries. Bootstrap doesn't do this for you, but it's fairly easy to add if you need it.
-
-Here's an example of it in practice. Choose whatever `font-size`s and media queries you wish.
+## Responsive font sizes
 
-{% highlight scss %}
-html {
-  font-size: 1rem;
-}
+Bootstrap v4.3 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.

-  }
-}

-@include media-breakpoint-up(lg) {
-  html {
-    font-size: 1.6rem;
-  }
-}
-{% endhighlight %}
+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).

+        <p>This example is a quick exercise to illustrate how the navbar and its contents work. Some navbars extend the width of the viewport, others are confined within a <code>.container</code>. For positioning of navbars, checkout the <a href="{{ site.baseurl }}/docs/{{ site.docs_version }}/examples/navbar-static/">top</a> and <a href="{{ site.baseurl }}/docs/{{ site.docs_version }}/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>

 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.

+### 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`.

+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.
+
+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.
+
+{% capture example %}
+<div class="card" style="width: 18rem;">
+  {% include icons/placeholder.svg 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>
+{% endcapture %}
+{% include example.html content=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.
+
+{% capture example %}
+<div class="media position-relative">
+  {% include icons/placeholder.svg width="144" height="144" class="mr-3" text=" " title="Generic placeholder image" %}

+{% endcapture %}
+{% include example.html content=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.
+
+{% capture example %}
+<div class="row no-gutters bg-light position-relative">
+  <div class="col-md-6 mb-md-0 p-md-4">

+
+## 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)
