BTW, I think another issue is the urge to can tables altogether. Unfortunately, with so many different browsers, it’s nearly impossible to get a fluid look without tables, and exact placements using CSS tend to cause some issues.
I wonder how many bloggers look in IE, FireFox, NS, Opera, Safari, etc? Most just test with two browsers, but since most of my sites are ecommerce, such code needs to work on vast majority of platforms.
