The background: black makes a basic case strange: fullscreening
<div>hello</div> will result in black text on a black background. Maybe
having that on video:fullscreen and maybe img:fullscreen makes sense,

doesn't seem right in general.
Should margin: 0; padding: 0; be set by :fullscreen?
The current spec doesn't seem to allow asking permission to fullscreen in
advance, since the fullscreen element is set synchronously. This should
be
supported; there are a lot of potential problems with the ask-after model
and it shouldn't be the only model supported.
:fullscreen { width: 100%; height: 100%; } will stretch videos and
images to
fit the screen, instead of doing something more sensible (letterboxing,
pillarboxing or cropping, depending on aspect ratios and the user or
site's
preference). I'm not sure how that should work in general, but
fullscreening a video wouldn't be as simple as video.requestFullScreen().
(I don't recall if <video> can handle cropping and letterboxing directly;
for example, you don't want to blindly crop a video without the video
knowing about it, or WebVTT subtitles and native controls would get
cropped
too.)
<video> already shows the video with correct aspect ratio; it has default
style object-fit:contain. <img> would be stretched, though. We could make
it object-fit:contain when it's the fullscreen element.
