For keeping YouTube video aspect ratio as the window resizes so there are not black bars on top/bottom of the video. Not entirely sure this is the best way to do this, so feel free to edit/replace with another method if you have one. This seems to work, though.
Requires width/height attributes from the YouTube standard embed tag.
How To - script.js
$(window).on('resize load', function(){
$('iframe[src*=youtube').each(function(){
$(this).css('height', $(this).attr('height') / $(this).attr('width') * $(this).outerWidth());
})
})
