[whatwg] width and height

[Perry Smith]

I'm trying to piece some things together.  I end up with this idea:

ele.style.height returns the "used" value if display is not set to  
none.  By "used" value I assume the CSSOM spec means the actual value  
used.  e.g. if the span takes up 100 pixels, it would return a value  
equivalent to 100px.  But its not defined.

I see a few old messages on this list about clientWidth and innerWidth  
and a reply that they were moved to CSSOM but there is nothing really  
defined in the copy of CSSOM I'm looking at.  I also don't see a  
mailing list to discuss it so I thought I'd ask here.

Thank you,
Perry
