Trying to transform this... http://jsfiddle.net/K2NPz/1/
Into this...
The image on the left is current, while the one on the right is the desired outcome. However, I'm facing challenges making it work as intended due to issues with the inherit property and the 100% value not functioning correctly. It does work in Quirks mode, but my goal is to have it functional with a standard Doctype like HTML5 or XHTML 1.0 Strict.
