The initial containing block is the viewport, but you can make it the root
element just by saying:
:root { position: relative; }
...and then the 'height' property on absolutely positioned elements other
than the root element will be relative to the root element instead of the
viewport. Not sure how well that is supported. Try 'html' instead of
':root' if you want it to work in WinIE.
Note: CSS2 disagrees with the above. This is one of the current proposed
changes to CSS2.1. This area of the spec is not without controvery,
though, so I don't guarentee that the final text will agree with me. :-)
