Figuration v4.4 is now available!

Embed

Determine embedded media dimensions based on the width of their containing block by creating an intrinsic ratio that will scale on any device.

Overview

Rules are directly applied to <iframe>, <embed>, <video>, and <object> elements; optionally use an explicit descendant class .embed-fluid-item when you want to match the styling for other attributes.

Examples

Inline Frames

Pro-Tip! You don't need to include frameborder="0" in your <iframe>s as we override that for you in the Reboot styles.

<div class="embed-fluid embed-fluid-16x9">
<iframe class="embed-fluid-item" src="https://www.youtube.com/embed/MbGkL06EU90?rel=0" title="YouTube video" allowfullscreen></iframe>
</div>

Video Element

<div class="embed-fluid">
<video poster="/assets/4.1/video/niagara_falls.jpg" controls>
<source src="/assets/4.1/video/niagara_falls.mp4">
<track src="/assets/4.1/video/niagara_falls-en.vtt" label="English" kind="subtitles" srclang="en" default />
</video>
</div>

Aspect Ratios

By default the aspect ratio is set to 16:9, this can be customized by overriding the $embed-ratio settings variable. Also, the aspect ratios can be customized with the included modifier classes. By default the following aspect ratio classes are provided:

<!-- 21:9 aspect ratio -->
<div class="embed-fluid embed-fluid-21x9">
<iframe class="embed-fluid-item" src="..."></iframe>
</div>

<!-- 16:9 aspect ratio -->
<div class="embed-fluid embed-fluid-16x9">
<iframe class="embed-fluid-item" src="..."></iframe>
</div>

<!-- 4:3 aspect ratio -->
<div class="embed-fluid embed-fluid-4x3">
<iframe class="embed-fluid-item" src="..."></iframe>
</div>

<!-- 1:1 aspect ratio -->
<div class="embed-fluid embed-fluid-1x1">
<iframe class="embed-fluid-item" src="..."></iframe>
</div>

It is possible to alter the available aspect ratios. These are the default aspect ratio setting and Sass map in _settings.scss:

$embed-fluid-default-ratio: percentage(9 / 16) !default;
$embed-fluid-aspect-ratios: (
"21x9": (
x: 21,
y: 9
),
"16x9": (
x: 16,
y: 9
),
"4x3": (
x: 4,
y: 3
),
"1x1": (
x: 1,
y: 1
)
);

Additional aspect ratio classes can also be disabled in your custom settings using:

$embed-fluid-aspect-ratios: false;
