Videos

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 <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.

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/c5CaIOgNjnU?rel=0" allowfullscreen></iframe>
</div>

Aspect ratios

Aspect ratios can be customized with modifier classes.

21:9 aspect ratio

16:9 aspect ratio

4:3 aspect ratio

1:1 aspect ratio

<div class="row">
     <div class="col-lg-6 mb-3">
     <h3>21:9 aspect ratio</h3>
