Vimeo Video as Background

Use Vimeo as a performant option to create background videos behind content.

See an example of it in use on CodePen here: https://codepen.io/CoreyMoen/pen/WNxNgPj 

Note: you must have at least a Vimeo Pro account to be able to use the "?background=1" parameter that makes this work automatically with autoplay, but no audio or controls.
