I'm using CSS positioning for my site, and I want the footer div to sit below the content div. Since the content div will always be changing sizes, I'm trying to get at it's height, or it's bottom, so that I can calculate where to put my footer. Reading the DOM 1 spec, I see that the only attribute that DIV has is ALIGN. Bummer. Can someone suggest a manner in which I can find out where the bottom of a given div is? Thanks.
