Play and Pause Buttons for YouTube and Vimeo Videos (via Their APIs)

The Vimeo player API actually works by sending commands through <span style="color: #2e2f3e;">postMessage</span> right to the iframe. You don’t need the froogaloop library to do that, but <span style="color: #2e2f3e;">postMessage</span> has some inherent complexities that this library (by Vimeo themselves) makes way easier. Plus it’s only 1.8kb so I’d recommend it.
