Embeds
Bootstrap embeds is a utility which helps you insert video or slideshow in the page keeping width of the parent and scales on any device.
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>
s 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="https://www.youtube.com/embed/vlDzYIIOYmM" allowfullscreen></iframe>
</div>
Aspect ratios can be customized with modifier classes.
<!-- 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>
