Having an embedded media (photos and video) is often inflexible with a dynamic and responsive design.

Embed your video like this:

<div class="icontain">
  <iframe src="//www.youtube.com/embed/8yis7GzlXNM" allowfullscreen></iframe>

It’ll play like this funny video below! Try resizing the page!

Photo layouts are also really cool and dynamically resizable. Check out the photos/gallery section at magiciansanfrancisco.com for a demo and see the source code for how.
