That is already the case, at least in the example you provide. The top:, 
left:, bottom: and right: properties are meant to be used in conjunction 
with absolute positioning. That is precisely why I asked why Kris did 
use margin instead. He was unnecessarily mixing two posioning methods. 
Of course, when margin is used to create spacing *within* absolutely 
positioned areas, as I believe Kris did in a later example, it is 
relatively safe and correct.
