-description: Quickly and easily clear floated content within a container by adding a clearfix utility.
-group: helpers
-aliases: "/docs/5.2/helpers/"
----
-
-Easily clear `float`s by adding `.clearfix` **to the parent element**. Can also be used as a mixin.
-
-Use in HTML:
-
-```html
-<div class="clearfix">...</div>
-```
-
-The mixin source code:
-
-{{< scss-docs name="clearfix" file="scss/mixins/_clearfix.scss" >}}
-
-Use the mixin in SCSS:
-
-```scss
-.element {
-  @include clearfix;
-}
-```
-
-The following example shows how the clearfix can be used. Without the clearfix the wrapping div would not span around the buttons which would cause a broken layout.
-
-{{< example >}}
-<div class="bg-info clearfix">
-  <button type="button" class="btn btn-secondary float-start">Example Button floated left</button>
-  <button type="button" class="btn btn-secondary float-end">Example Button floated right</button>
-</div>

----

-## Overview
-
-{{< added-in "5.2.0" >}}
-
-Color and background helpers combine the power of our [`.text-*` utilities]({{< docsref "/utilities/colors" >}}) and [`.bg-*` utilities]({{< docsref "/utilities/background" >}}) in one class. Using our Sass `color-contrast()` function, we automatically determine a contrasting `color` for a particular `background-color`.
-
-{{< callout warning >}}
-**Heads up!** There's currently no support for a CSS-native `color-contrast` function, so we use our own via Sass. This means that customizing our theme colors via CSS variables may cause color contrast issues with these utilities.
-{{< /callout >}}
-
-{{< example >}}
-{{< text-bg.inline >}}
-{{- range (index $.Site.Data "theme-colors") }}
-<div class="text-bg-{{ .name }} p-3">{{ .name | title }} with contrasting color</div>
-{{- end -}}
-{{< /text-bg.inline >}}
-{{< /example >}}
-
-## With components
-
-Use them in place of combined `.text-*` and `.bg-*` classes, like on [badges]({{< docsref "/components/badge#background-colors" >}}):
-
-{{< example >}}
-<span class="badge text-bg-primary">Primary</span>
-<span class="badge text-bg-info">Info</span>
-{{< /example >}}
-
-Or on [cards]({{< docsref "/components/card#background-and-color" >}}):
-
-{{< example >}}
-<div class="card text-bg-primary mb-3" style="max-width: 18rem;">
-  <div class="card-header">Header</div>
-  <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>
-<div class="card text-bg-info mb-3" style="max-width: 18rem;">
-  <div class="card-header">Header</div>
-  <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>

-title: Ratios
-description: Use generated pseudo elements to make an element maintain the aspect ratio of your choosing. Perfect for responsively handling video or slideshow embeds based on the width of the parent.
-group: helpers
-toc: true
----
-
-## About
-
-Use the ratio helper to manage the aspect ratios of external content like `<iframe>`s, `<embed>`s, `<video>`s, and `<object>`s. These helpers also can be used on any standard HTML child element (e.g., a `<div>` or `<img>`). Styles are applied from the parent `.ratio` class directly to the child.
-
-Aspect ratios are declared in a Sass map and included in each class via CSS variable, which also allows [custom aspect ratios](#custom-ratios).
-
-{{< callout info >}}
-**Pro-Tip!** You don't need `frameborder="0"` on your `<iframe>`s as we override that for you in [Reboot]({{< docsref "/content/reboot" >}}).
-{{< /callout >}}
-
-## Example
-
-Wrap any embed, like an `<iframe>`, in a parent element with `.ratio` and an aspect ratio class. The immediate child element is automatically sized thanks to our universal selector `.ratio > *`.
-
-{{< example >}}
-<div class="ratio ratio-16x9">
-  <iframe src="https://www.youtube.com/embed/zpOULjyy-n8?rel=0" title="YouTube video" allowfullscreen></iframe>
-</div>
-{{< /example >}}
-
-## Aspect ratios
-
-Aspect ratios can be customized with modifier classes. By default the following ratio classes are provided:
-
-{{< example class="bd-example-ratios" >}}
-<div class="ratio ratio-1x1">
-  <div>1x1</div>
-</div>
-<div class="ratio ratio-4x3">
-  <div>4x3</div>
-</div>
-<div class="ratio ratio-16x9">
-  <div>16x9</div>
-</div>
-<div class="ratio ratio-21x9">
-  <div>21x9</div>
-</div>
-{{< /example >}}
-
-## Custom ratios
-
-Each `.ratio-*` class includes a CSS custom property (or CSS variable) in the selector. You can override this CSS variable to create custom aspect ratios on the fly with some quick math on your part.
-
-For example, to create a 2x1 aspect ratio, set `--bs-aspect-ratio: 50%` on the `.ratio`.
-
-{{< example class="bd-example-ratios" >}}
-<div class="ratio" style="--bs-aspect-ratio: 50%;">
-  <div>2x1</div>
-</div>
-{{< /example >}}
-
-This CSS variable makes it easy to modify the aspect ratio across breakpoints. The following is 4x3 to start, but changes to a custom 2x1 at the medium breakpoint.
-
-```scss
-.ratio-4x3 {
-  @include media-breakpoint-up(md) {
-    --bs-aspect-ratio: 50%; // 2x1
-  }
-}
-```
-
-{{< example class="bd-example-ratios bd-example-ratios-breakpoint" >}}
-<div class="ratio ratio-4x3">
-  <div>4x3, then 2x1</div>
-</div>
-{{< /example >}}
-
-
-## Sass map
-
-Within `_variables.scss`, you can change the aspect ratios you want to use. Here's our default `$ratio-aspect-ratios` map. Modify the map as you like and recompile your Sass to put them to use.

-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
-added: "5.1"
----
-
-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>
-{{< /example >}}

-title: Stretched link
-description: Make any HTML element or Bootstrap component clickable by "stretching" a nested link via CSS.
-group: helpers
----
-
-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="false" 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 >}}
-
-Most custom components do not have `position: relative` by default, so we need to add the `.position-relative` here to prevent the link from stretching outside the parent element.
-
-{{< example >}}
-<div class="d-flex position-relative">
-  {{< placeholder width="144" height="144" class="flex-shrink-0 me-3" text="false" title="Generic placeholder image" >}}
-  <div>
-    <h5 class="mt-0">Custom component with stretched link</h5>
-    <p>This is some placeholder content for the 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 >}}
-
-{{< example >}}
-<div class="row g-0 bg-light position-relative">
-  <div class="col-md-6 mb-md-0 p-md-4">
-    {{< placeholder width="100%" height="200" class="w-100" text="false" title="Generic placeholder image" >}}
-  </div>
-  <div class="col-md-6 p-4 ps-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="false" title="Card image cap" >}}

-    <h5 class="card-title">Card with stretched links</h5>

-    <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.

-## How it works
-
-Vertical rules are inspired by the `<hr>` element, allowing you to create vertical dividers in common layouts. They're styled just like `<hr>` elements:
-
-- They're `1px` wide
-- They have `min-height` of `1em`
-- Their color is set via `currentColor` and `opacity`
-
-Customize them with additional styles as needed.
-
-## Example
-
-{{< example >}}
-<div class="vr"></div>
-{{< /example >}}
-
-Vertical rules scale their height in flex layouts:

-
-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.
