Create responsive video or slideshow embeds based on the width of the parent by creating an intrinsic ratio that scales on any device.
Rules are directly applied to
<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.
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/AQXpkbXOY3k" allowfullscreen></iframe> </div>
Aspect ratios can be customized with modifier classes.
