 Just add `data-bs-toggle="collapse"` and a `data-bs-target` to the element to automatically assign control of one or more collapsible elements. The `data-bs-target` attribute accepts a CSS selector to apply the collapse to. Be sure to add the class `collapse` to the collapsible element.

 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.

+title: Placeholders
+description: Use loading placeholders for your components or pages to indicate something may still be loading.
+group: components
+toc: true
+---
+
+## About
+
+Placeholders can be used to enhance the experience of your application. 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, color, and sizing can be easily customized with our utility classes.
+
+## Example
+
+In the example below, we take a typical card component and recreate it with placeholders applied to create a "loading card". Size and proportions are the same between the two.
+
+<div class="bd-example bd-example-placeholder-cards d-flex justify-content-around">
+<div class="card">
+  {{< placeholder width="100%" height="180" class="card-img-top" text="false" background="#20c997" >}}
+  <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>
+
+<div class="card" aria-hidden="true">
+  {{< placeholder width="100%" height="180" class="card-img-top" text="false" >}}
+  <div class="card-body">
+    <div class="h5 card-title placeholder-glow">
+      <span class="placeholder col-6"></span>
+    </div>
+    <p class="card-text placeholder-glow">
+      <span class="placeholder col-7"></span>
+      <span class="placeholder col-4"></span>
+      <span class="placeholder col-4"></span>
+      <span class="placeholder col-6"></span>
+      <span class="placeholder col-8"></span>
+    </p>
+    <a href="#" tabindex="-1" class="btn btn-primary disabled placeholder col-6"></a>
+  </div>
+</div>
+</div>
+
+```html
+<div class="card">
+  <img src="..." class="card-img-top" alt="...">
+
+  <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>
+
+<div class="card" aria-hidden="true">
+  <img src="..." class="card-img-top" alt="...">
+  <div class="card-body">
+    <h5 class="card-title placeholder-glow">
+      <span class="placeholder col-6"></span>
+    </h5>
+    <p class="card-text placeholder-glow">
+      <span class="placeholder col-7"></span>
+      <span class="placeholder col-4"></span>
+      <span class="placeholder col-4"></span>
+      <span class="placeholder col-6"></span>
+      <span class="placeholder col-8"></span>
+    </p>
+    <a href="#" tabindex="-1" class="btn btn-primary disabled placeholder col-6"></a>
+  </div>
+</div>
+```
+
+## How it works
+
+Create placeholders with the `.placeholder` class and a grid column class (e.g., `.col-6`) to set the `width`. They can replace the text inside an element or be added as a modifier class to an existing component.
+
+We apply additional styling to `.btn`s via `::before` to ensure the `height` is respected. You may extend this pattern for other situations as needed, or add a `&nbsp;` within the element to reflect the height when actual text is rendered in its place.
+
+{{< example >}}
+<p aria-hidden="true">
+  <span class="placeholder col-6"></span>
+</p>
+
+<a href="#" tabindex="-1" class="btn btn-primary disabled placeholder col-4" aria-hidden="true"></a>
+{{< /example >}}
+
+{{< callout info >}}
+The use of `aria-hidden="true"` only indicates that the element should be hidden to screen readers. The *loading* behavior of the placeholder depends on how authors will actually use the placeholder styles, how they plan to update things, etc. Some JavaScript code may be needed to *swap* the state of the placeholder and inform AT users of the update.
+{{< /callout >}}
+
+### Width
+
+You can change the `width` through grid column classes, width utilities, or inline styles.
+
+{{< example >}}
+<span class="placeholder col-6"></span>
+<span class="placeholder w-75"></span>
+<span class="placeholder" style="width: 25%;"></span>
+{{< /example >}}
+
+### Color
+
+By default, the `placeholder` uses `currentColor`. This can be overridden with a custom color or utility class.
+
+{{< example >}}
+<span class="placeholder col-12"></span>
+{{< placeholders.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<span class="placeholder col-12 bg-{{ .name }}"></span>
+{{- end -}}
+{{< /placeholders.inline >}}
+{{< /example >}}
+
+### Sizing
+
+The size of `.placeholder`s are based on the typographic style of the parent element. Customize them with sizing modifiers: `.placeholder-lg`, `.placeholder-sm`, or `.placeholder-xs`.
+
+{{< example >}}
+<span class="placeholder col-12 placeholder-lg"></span>
+<span class="placeholder col-12"></span>
+<span class="placeholder col-12 placeholder-sm"></span>
+<span class="placeholder col-12 placeholder-xs"></span>
+{{< /example >}}
+
+### Animation
+
+Animate placeholders with `.placeholder-glow` or `.placeholder-wave` to better convey the perception of something being _actively_ loaded.
+
+{{< example >}}
+<p class="placeholder-glow">
+  <span class="placeholder col-12"></span>
+</p>
+
+<p class="placeholder-wave">
+  <span class="placeholder col-12"></span>
+</p>

 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.
 
+## CSS variables
+
+As Bootstrap 5 continues to mature, more and more styles will be built with [CSS variables]({{< docsref "/customize/css-variables" >}}) as a means to provide more real-time customization without the need to always recompile Sass. Our approach is to take our source Sass variables and transform them into CSS variables. That way, even if you don't use CSS variables, you still have all the power of Sass. **This is still in-progress and will take time to fully implement.**
+
+For example, consider these `:root` CSS variables for common `<body>` styles:
+
+{{< scss-docs name="root-body-variables" file="scss/_root.scss" >}}
+
+In practice, those variables are then applied in Reboot like so:
+
+{{< scss-docs name="reboot-body-rules" file="scss/_reboot.scss" >}}
+
+Which allows you to make real-time customizations however you like:
+
+```html
+<body style="--bs-body-color: #333;">
+  <!-- ... -->
+</body>
+```

+## Generating utilities
+
+<small class="d-inline-flex px-2 py-1 font-monospace text-muted border rounded-3">Added in v5.1.0</small>
+
+Bootstrap doesn't include `color` and `background-color` utilities for every color variable, but you can generate these yourself with our [utility API]({{< docsref "/utilities/api" >}}) and our extended Sass maps added in v5.1.0.
+
+1. To start, make sure you've imported our functions, variables, mixins, and utilities.
+2. Use our `map-merge-multiple()` function to quickly merge multiple Sass maps together in a new map.
+3. Merge this new combined map to extend any utility with a `{color}-{level}` class name.
+
+Here's an example that generates text color utilities (e.g., `.text-purple-500`) using the above steps.
+
+```scss
+@import "bootstrap/scss/functions";
+@import "bootstrap/scss/variables";
+@import "bootstrap/scss/mixins";
+@import "bootstrap/scss/utilities";
+
+$all-colors: map-merge-multiple($blues, $indigos, $purples, $pinks, $reds, $oranges, $yellows, $greens, $teals, $cyans);

+      map-get($utilities, "color"),
+      (
+        values: map-merge(

+    ),
+  )
+);
+
+@import "bootstrap/scss/utilities/api";

+
+This will generate new `.text-{color}-{level}` utilities for every color and level. You can do the same for any other utility and property as well.

-A switch has the markup of a custom checkbox but uses the `.form-switch` class to render a toggle switch. Switches also support the `disabled` attribute.
+A switch has the markup of a custom checkbox but uses the `.form-switch` class to render a toggle switch. Consider using `role="switch"` to more accurately convey the nature of the control to assistive technologies that support this role. In older assistive technologies, it will simply be announced as a regular checkbox as a fallback. Switches also support the `disabled` attribute.

-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.
+Bootstrap uses [npm scripts](https://docs.npmjs.com/misc/scripts/) to build the documentation and compile source files. Our [package.json]({{< param repo >}}/blob/v{{< param current_version >}}/package.json) houses these scripts for compiling code, running tests, and more. These aren't intended for use outside our repository and documentation.
 
 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:

+title: Stacks
+description: Shorthand helpers that build on top of our flexbox utilities to make component layout faster and easier than ever.
+group: helpers
+toc: true
+---
+
+Stacks offer a shortcut for applying a number of flexbox properties to quickly and easily create layouts in Bootstrap. All credit for the concept and implementation goes to the open source [Pylon project](https://almonk.github.io/pylon/).
+
+{{< callout warning >}}
+Heads up! Support for gap utilities with flexbox was recently added to Safari, so consider verifying your intended browser support. Grid layout should have no issues. [Read more](https://caniuse.com/flexbox-gap).
+{{< /callout >}}
+
+## Vertical
+
+Use `.vstack` to create vertical layouts. Stacked items are full-width by default. Use `.gap-*` utilities to add space between items.
+
+{{< example >}}
+<div class="vstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border">Second item</div>
+  <div class="bg-light border">Third item</div>
+</div>
+{{< /example >}}
+
+## Horizontal
+
+Use `.hstack` for horizontal layouts. Stacked items are vertically centered by default and only take up their necessary width. Use `.gap-*` utilities to add space between items.
+
+{{< example >}}
+<div class="hstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border">Second item</div>
+  <div class="bg-light border">Third item</div>
+</div>
+{{< /example >}}
+
+Using horizontal margin utilities like `.ms-auto` as spacers:
+
+{{< example >}}
+<div class="hstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border ms-auto">Second item</div>
+  <div class="bg-light border">Third item</div>
+</div>
+{{< /example >}}
+
+And with [vertical rules]({{< docsref "/helpers/vertical-rule" >}}):
+
+{{< example >}}
+<div class="hstack gap-3">
+  <div class="bg-light border">First item</div>
+  <div class="bg-light border ms-auto">Second item</div>
+  <div class="vr"></div>
+  <div class="bg-light border">Third item</div>
+</div>
+{{< /example >}}
+
+## Examples
+
+Use `.vstack` to stack buttons and other elements:
+
+{{< example >}}
+<div class="vstack gap-2 col-md-5 mx-auto">
+  <button type="button" class="btn btn-secondary">Save changes</button>
+  <button type="button" class="btn btn-outline-secondary">Cancel</button>
+</div>
+{{< /example >}}
+
+Create an inline form with `.hstack`:
+
+{{< example >}}
+<div class="hstack gap-3">
+  <input class="form-control me-auto" type="text" placeholder="Add your item here..." aria-label="Add your item here...">
+  <button type="button" class="btn btn-secondary">Submit</button>
+  <div class="vr"></div>
+  <button type="button" class="btn btn-outline-danger">Reset</button>
+</div>

 Visually hide an element while still allowing it to be exposed to assistive technologies (such as screen readers) with `.visually-hidden`. Use `.visually-hidden-focusable` to visually hide an element by default, but to display it when it's focused (e.g. by a keyboard-only user). `.visually-hidden-focusable` can also be applied to a container–thanks to `:focus-within`, the container will be displayed when any child element of the container receives focus.

+title: CSS Grid
+description: Learn how to enable, use, and customize our alternate layout system built on CSS Grid with examples and code snippets.
+group: layout
+toc: true
+---
+
+Bootstrap's default grid system represents the culmination of over a decade of CSS layout techniques, tried and tested by millions of people. But, it was also created without many of the modern CSS features and techniques we're seeing in browsers like the new CSS Grid.
+
+{{< callout warning >}}
+**Heads up—our CSS Grid system is experimental and opt-in as of v5.1.0!** We included it in our documentation's CSS to demonstrate it for you, but it's disabled by default. Keep reading to learn how to enable it in your projects.
+{{< /callout >}}
+
+## How it works
+
+With Bootstrap 5, we've added the option to enable a separate grid system that's built on CSS Grid, but with a Bootstrap twist. You still get classes you can apply on a whim to build responsive layouts, but with a different approach under the hood.
+
+- **CSS Grid is opt-in.** Disable the default grid system by setting `$enable-grid-classes: false` and enable the CSS Grid by setting `$enable-cssgrid: true`. Then, recompile your Sass.
+
+- **Replace instances of `.row` with `.grid`.** The `.grid` class sets `display: grid` and creates a `grid-template` that you build on with your HTML.
+
+- **Replace `.col-*` classes with `.g-col-*` classes.** This is because our CSS Grid columns use the `grid-column` property instead of `width`.
+
+- **Columns and gutter sizes are set via CSS variables.** Set these on the parent `.grid` and customize however you want, inline or in a stylesheet, with `--bs-columns` and `--bs-gap`.
+
+In the future, Bootstrap will likely shift to a hybrid solution as the `gap` property has achieved nearly full browser support for flexbox.
+
+## Key differences
+
+Compared to the default grid system:
+
+- Flex utilities don't affect the CSS Grid columns in the same way.
+
+- Gaps replaces gutters. The `gap` property replaces the horizontal `padding` from our default grid system and functions more like `margin`.
+
+- As such, unlike `.row`s, `.grid`s have no negative margins and margin utilities cannot be used to change the grid gutters. Grid gaps are applied horizontally and vertically by default. See the [customizing section](#customizing) for more details.
+
+- Inline and custom styles should be viewed as replacements for modifier classes (e.g., `style="--bs-columns: 3;"` vs `class="row-cols-3"`).
+
+- Nesting works similarly, but may require you to reset your column counts on each instance of a nested `.grid`. See the [nesting section](#nesting) for details.
+
+## Examples
+
+### Three columns
+
+Three equal-width columns across all viewports and devices can be created by using the `.g-col-4` classes. Add [responsive classes](#responsive) to change the layout by viewport size.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div class="g-col-4">.g-col-4</div>
+  <div class="g-col-4">.g-col-4</div>
+  <div class="g-col-4">.g-col-4</div>
+</div>
+{{< /example >}}
+
+### Responsive
+
+Use responsive classes to adjust your layout across viewports. Here we start with two columns on the narrowest viewports, and then grow to three columns on medium viewports and above.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div class="g-col-6 g-col-md-4">.g-col-6 .g-col-md-4</div>
+  <div class="g-col-6 g-col-md-4">.g-col-6 .g-col-md-4</div>
+  <div class="g-col-6 g-col-md-4">.g-col-6 .g-col-md-4</div>
+</div>
+{{< /example >}}
+
+Compare that to this two column layout at all viewports.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+</div>
+{{< /example >}}
+
+## Wrapping
+
+Grid items automatically wrap to the next line when there's no more room horizontally. Note that the `gap` applies to horizontal and vertical gaps between grid items.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+</div>
+{{< /example >}}
+
+## Starts
+
+Start classes aim to replace our default grid's offset classes, but they're not entirely the same. CSS Grid creates a grid template through styles that tell browsers to "start at this column" and "end at this column." Those properties are `grid-column-start` and `grid-column-end`. Start classes are shorthand for the former. Pair them with the column classes to size and align your columns however you need. Start classes begin at `1` as `0` is an invalid value for these properties.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div class="g-col-3 g-start-2">.g-col-3 .g-start-2</div>
+  <div class="g-col-4 g-start-6">.g-col-4 .g-start-6</div>
+</div>
+{{< /example >}}
+
+## Auto columns
+
+When there are no classes on the grid items (the immediate children of a `.grid`), each grid item will automatically be sized to one column.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+</div>
+{{< /example >}}
+
+This behavior can be mixed with grid column classes.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid">
+  <div class="g-col-6">.g-col-6</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+  <div>1</div>
+</div>
+{{< /example >}}
+
+## Nesting
+
+Similar to our default grid system, our CSS Grid allows for easy nesting of `.grid`s. However, unlike the default, this grid inherits changes in the rows, columns, and gaps. Consider the example below:
+
+- We override the default number of columns with a local CSS variable: `--bs-columns: 3`.
+- In the first auto-column, the column count is inherited and each column is one-third of the available width.
+- In the second auto-column, we've reset the column count on the nested `.grid` to 12 (our default).
+- The third auto-column has no nested content.
+
+In practice this allows for more complex and custom layouts when compared to our default grid system.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-columns: 3;">
+  <div>
+    First auto-column
+    <div class="grid">
+      <div>Auto-column</div>
+      <div>Auto-column</div>
+    </div>
+  </div>
+  <div>
+    Second auto-column
+    <div class="grid" style="--bs-columns: 12;">
+      <div class="g-col-6">6 of 12</div>
+      <div class="g-col-4">4 of 12</div>
+      <div class="g-col-2">2 of 12</div>
+    </div>
+  </div>
+  <div>Third auto-column</div>
+</div>
+{{< /example >}}
+
+## Customizing
+
+Customize the number of columns, the number of rows, and the width of the gaps with local CSS variables.
+
+{{< bs-table "table" >}}
+| Variable | Fallback value | Description |
+| --- | --- | --- |
+| `--bs-rows` | `1` | The number of rows in your grid template |
+| `--bs-columns` | `12` | The number of columns in your grid template |
+| `--bs-gap` | `1.5rem` | The size of the gap between columns (vertical and horizontal) |
+{{< /bs-table >}}
+
+These CSS variables have no default value; instead, they apply fallback values that are used _until_ a local instance is provided. For example, we use `var(--bs-rows, 1)` for our CSS Grid rows, which ignores `--bs-rows` because that hasn't been set anywhere yet. Once it is, the `.grid` instance will use that value instead of the fallback value of `1`.
+
+### No grid classes
+
+Immediate children elements of `.grid` are grid items, so they'll be sized without explicitly adding a `.g-col` class.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-columns: 3;">
+  <div>Auto-column</div>
+  <div>Auto-column</div>
+  <div>Auto-column</div>
+</div>
+{{< /example >}}
+
+### Columns and gaps
+
+Adjust the number of columns and the gap.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-columns: 4; --bs-gap: 5rem;">
+  <div class="g-col-2">.g-col-2</div>
+  <div class="g-col-2">.g-col-2</div>
+</div>
+{{< /example >}}
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-columns: 10; --bs-gap: 1rem;">
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-4">.g-col-4</div>
+</div>
+{{< /example >}}
+
+### Adding rows
+
+Adding more rows and changing the placement of columns:
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-rows: 3; --bs-columns: 3;">
+  <div>Auto-column</div>
+  <div class="g-start-2" style="grid-row: 2">Auto-column</div>
+  <div class="g-start-3" style="grid-row: 3">Auto-column</div>
+</div>
+{{< /example >}}
+
+### Gaps
+
+Change the vertical gaps only by modifying the `row-gap`. Note that we use `gap` on `.grid`s, but `row-gap` and `column-gap` can be modified as needed.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="row-gap: 0;">
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+</div>
+{{< /example >}}
+
+Because of that, you can have different vertical and horizontal `gap`s, which can take a single value (all sides) or a pair of values (vertical and horizontal). This can be applied with an inline style for `gap`, or with our `--bs-gap` CSS variable.
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-gap: .25rem 1rem;">
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+
+  <div class="g-col-6">.g-col-6</div>
+  <div class="g-col-6">.g-col-6</div>
+</div>
+{{< /example >}}
+
+## Sass
+
+One limitation of the CSS Grid is that our default classes are still generated by two Sass variables, `$grid-columns` and `$grid-gutter-width`. This effectively predetermines the number of classes generated in our compiled CSS. You have two options here:
+
+- Modify those default Sass variables and recompile your CSS.
+- Use inline or custom styles to augment the provided classes.
+
+For example, you can increase the column count and change the gap size, and then size your "columns" with a mix of inline styles and predefined CSS Grid column classes (e.g., `.g-col-4`).
+
+{{< example class="bd-example-cssgrid" >}}
+<div class="grid" style="--bs-columns: 18; --bs-gap: .5rem;">
+  <div style="grid-column: span 14;">14 columns</div>
+  <div class="g-col-4">.g-col-4</div>
+</div>
+{{< /example >}}

-### Custom class prefix
+### Property
+
+The required `property` key must be set for any utility, and it must contain a valid CSS property. This property is used in the generated utility's ruleset. When the `class` key is omitted, it also serves as the default class name. Consider the `text-decoration` utility:
+
+```scss
+$utilities: (
+  "text-decoration": (
+    property: text-decoration,
+    values: none underline line-through
+  )
+);

+.text-decoration-none { text-decoration: none !important; }
+.text-decoration-underline { text-decoration: underline !important; }
+.text-decoration-line-through { text-decoration: line-through !important; }
+```
+
+### Values
+
+Use the `values` key to specify which values for the specified `property` should be used in the generated class names and rules. Can be a list or map (set in the utilities or in a Sass variable).
+
+As a list, like with [`text-decoration` utilities]({{< docsref "/utilities/text#text-decoration" >}}):
+
+```scss
+values: none underline line-through
+```
+
+As a map, like with [`opacity` utilities]({{< docsref "/utilities/opacity" >}}):

+```
+
+### Local CSS variables
+
+Use the `local-vars` option to specify a Sass map that will generate local CSS variables within the utility class's ruleset. Please note that it may require additional work to consume those local CSS variables in the generated CSS rules. For example, consider our `.bg-*` utilities:
+
+```scss
+$utilities: (
+  "background-color": (
+    property: background-color,
+    class: bg,
+    local-vars: (

 ### Add utilities
 
 New utilities can be added to the default `$utilities` map with a `map-merge`. Make sure our required Sass files and `_utilities.scss` are imported first, then use the `map-merge` to add your additional utilities. For example, here's how to add a responsive `cursor` utility with three values.

+<small class="d-inline-flex px-2 py-1 font-monospace text-muted border rounded-3">Added in v5.1.0</small>
+
+As of v5.1.0, `background-color` utilities are generated with Sass using CSS variables. This allows for real-time color changes without compilation and dynamic alpha transparency changes.
+
+### How it works
+
+Consider our default `.bg-success` utility.
+
+```css
+.bg-success {
+  --bs-bg-opacity: 1;
+  background-color: rgba(var(--bs-success-rgb), var(--bs-bg-opacity)) !important;
+}
+```
+
+We use an RGB version of our `--bs-success` (with the value of `25, 135, 84`) CSS variable and attached a second CSS variable, `--bs-bg-opacity`, for the alpha transparency (with a default value `1` thanks to a local CSS variable). That means anytime you use `.bg-success` now, your computed `color` value is `rgba(25, 135, 84, 1)`. The local CSS variable inside each `.bg-*` class avoids inheritance issues so nested instances of the utilities don't automatically have a modified alpha transparency.
+
+### Example
+
+To change that opacity, override `--bs-bg-opacity` via custom styles or inline styles.
+
+{{< example >}}
+<div class="bg-success p-2 text-white">This is default success background</div>
+<div class="bg-success p-2" style="--bs-bg-opacity: .5;">This is 50% opacity success background</div>
+{{< /example >}}
+
+Or, choose from any of the `.bg-opacity` utilities:
+
+{{< example >}}
+<div class="bg-success p-2 text-white">This is default success background</div>
+<div class="bg-success p-2 text-white bg-opacity-75">This is 75% opacity success background</div>
