@Paul_JrFeb 28.2004 — #The [FONT=courier new]px[/FONT] (or [FONT=courier new]em[/FONT], [FONT=courier new]%[/FONT], [FONT=courier new]ex[/FONT], ect) isn't required if the value is 0. For anything else, it is.
Lemme see if I can dig up a link on this.
Try [URL=http://www.w3.org/TR/REC-CSS2/syndata.html#length-units]this one[/URL]. Finding stuff on that site is like trying to find a specific needle in a stack of 'em!
