/* This is for fluid media that is embedded from third party sites like youtube, vimeo etc.
 * Wrap the outer element in aspect-ratio and then extend it with the desired ratio i.e
 * Make sure there are no height and width attributes on the embedded media.
 * Adapted from: https://github.com/suitcss/components-flex-embed

 * Example:
 *
 * <div class="aspect-ratio aspect-ratio--16x9">
 *  <iframe class="aspect-ratio--object"></iframe>
