If you’re embedding a video from YouTube, Vimeo, or another site that uses iframe, embed or object elements, you can wrap your video in
div.flex-video to create an intrinsic ratio that will properly scale your video on any device.
Building flex-video containers using our classes is simple, you’ll just need to create a
<div class="flex-video">and apply the classes you want to style it appropriately.
The available class options:
widescreen: Will give the player a widescreen aspect ratio.
vimeo: This will ensure that we don’t add extra padding since Vimeo has controls within the player, itself.
