Not quite sure if this is what you mean, but the working group recently
decided to investigate the implications of allowing simple, linear
expressions as values. For example:
width: expr(50% + 5px);
font-size: expr(2em / 3 + 2px);
padding-right: expr(1px + 1ex - 5%);
They make life harder for GUI-based editors, but sometimes it is handy
to be able to add different kinds of units together.
Some common cases can be done without expressions, by means of a few new
units:
gd = the grid unit from CSS3 Text
rem = the font size of the root element
vw = the viewport width (or 1/100th of it)
vh = the viewport height (or 1/100th of it)
vm = min(vw, vh)
There is not even a draft yet, though.
