This is a super helpful tool for making a video responsive in your layout: http://embedresponsively.com
You place your Youtube video url within the box, and copy the resulting code into Hype within the inner HTML of a rectangle:
<style>
.embed-container
{ position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }
</style>
<div class='embed-container'>
<iframe allowfullscreen="" frameborder='0' src='http://www.youtube.com/embed/QILiHiTD3uc'></iframe>
</div>
