Alright. I had to make a video embed shortcode for a client and figured some folks may want to peek at it and maybe use it.
Basically, this allows your clients to add videos into their pages, include some padding and float, yet maintain the beauty of responsive design.
Currently only available for YouTube and Vimeo.
Let me know if you find this useful!
