In this example we want to have a ratio of 25:14 */
.aspect-ratio {
position: relative;
width: 100%;
height: 0;
padding-bottom: 56%; /* The height of the item will now be 56% of the width. */

/* Adjust the iframe so it's rendered in the outer-width and outer-height of it's parent */
.aspect-ratio iframe {
