Height in EM’s

Can anyone tell me why two divs(columns) in CSS using em’s for the height value move at different rates? Logically, since they’re both based on the same standard they should move equally. Unfortunately, this doesn’t seem to be the case.

  1. Though I’m not sure what you mean by “move,” I’m guessing that because em’s are based on a font size, that your problem may be related to that. Normally, using “px” as the unit for div heights is a safer way to go…

  2. “Move” as in, scale height wise. Scroll to the bottom of the page and use the mousewheel and ctrl to resize and you’ll see what I mean.
