Proposal for a background-video property

Has any serious consideration yet been given to adding a CSS background-video property?

There are already tons of articles explaining how to reposition the <video> tag for this. Since folks are doing it anyway seems that CSS background-video could save developers some work. Could also help discourage the use of bloated animated image types for this?

Seperation of concerns thinking would go: HTML for content video and CSS for background video. We have html and css background-image why not and css background-video?

I vaguely remember something about Safari considering allowing the use of video formats in background-image and treating them like animated GIFs by default (muted with auto repeat). But wouldn't there be special consideration for video that would require a separate background-video property (like playback speed, etc)?

background-video like background-image would need to work with (where possible) existing background- properties (-size, -position, etc..).

Start by reviewing the proposal and its comparison with , background-image, and existing background-* properties. Determine whether background-video needs separate semantics for playback and repetition, and what a complete CSS property definition would need to specify.
