About
Rules are directly applied to <iframe>
, <embed>
,
<video>
, and <object>
elements; optionally use an explicit descendant
class .embed-responsive-item
when you want to match the styling for other attributes.
Pro-Tip! You don’t need to include frameborder-"0"
in your
<iframe>
as we override that for you.
Example
Wrap any embed like an <iframe>
in a parent element with .embed-responsive
and
an aspect ratio. The .embed-responsive-item
isn’t strictly required, but we encourage it.
<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" src="/video/" title="Trimble video" loading="lazy"></iframe>
</div>
Aspect Ratios
Aspect ratios can be customized with modifier classes. By default, the following ratio classes are provided:
<!-- 21:9 aspect ratio -->
<div class="embed-responsive embed-responsive-21by9">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
<!-- 1:1 aspect ratio -->
<div class="embed-responsive embed-responsive-1by1">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
