If IE5 lets you get at the DOM, that sounds great. Navigator and IE don't always agree, but they are close enough that picking one over the other should bother _too_ many people. I suggest looking at large volumes of professional and home baked (e.g., GeoCities, Xoom, etc...) home pages when testing, as well as specially inventing ugly cases. - Tom
