Not quite Tab.

Depends on what you allow ::marker to do (see below).

No, the specs needs to state that animations apply to ::before and 
::after and the specs needs to state the expected behavior. I believe 
that both Safari and Chromes shows the expected behavior in this demo.


The expected behavior that I talking about is that the generated content 
(::after in the demo) must have it's perspective (vanishing point) 
anchored to the real element which is the frame (framework in demo) that 
rotates along the x axis.

I'm curious, is this the sort of behavior that you expect with ::marker?
