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. - -{{< scss-docs name="aspect-ratios" file="scss/_variables.scss" >}} |
