Menu
I am a newbie to AMP development and can't wrap my head around the layouts. I am trying to create full page cover background video.
I have tried variants of layout='responsive' but I won't know the height of the page prior to page load and AFAIK I can't update width or height prop dynamically after page load. I am essentially emulating the object-fit CSS prop. object-fit: cover is apparently supported by AMP CSS.
I tried using object-fit in the snippet below but to no avail. In the snippet the expected behaviour is displayed using normal HTML5 video tag in the expected div.

I think this is what you're looking for.
The video is in the background with fixed positioning with content in the foreground if desired.
