Video embeds are responsive and scale with the width of the main content block with the help of FitVids.

Adding YouTube video embeds causes errors when building your Jekyll site. To fix wrap the html within {::nomarkdown} tags. Example below:

{::nomarkdown}
<iframe width="560" height="315" src="//www.youtube.com/embed/SU3kYxJmWuQ" frameborder="0" allowfullscreen></iframe>
{:/nomarkdown}
