[whatwg] Fullscreen CSS

[Anne van Kesteren]

I have removed background:black as the way the rendering is defined at the  
moment is that it cannot be overridden unless !important is used. That's  
not ideal for backgrounds. Since no color was defined that did not help  
either.

I added margin:0; box-sizing:border-box so the height/width declarations  
make sense.

I also added transition:none to :fullscreen-ancestor per the comment that  
was present in the draft.

Latest draft:
