Well, as an author, you can always choose to make the body element go
fullscreen, wouldn't you?

So you can have both:
- use a single div with all it's content
- use a video element
- or use the body, so that the whole page goes fullscreen.

And if there is a pseudo-class on this element, you can always style the
content accordingly.
