I don't see why. Setting position:fixed does what you want in the cases I

Sorry I wasn't clear. By "in-page UI" I meant UI under the control of the

Indeed. A CSS pseudo-class sounds like a reasonable idea.

If you change the layout, zooming isn't really necessary. My guess is that
there are several interpolation strategies for transition effects that would
all work. For example, you could apply the style change, render the element
at the size of the screen, and then zoom that image out from the element's
old position to the screen size.
