Re: "simple" buttons - possible without tables?

You should always set a width on floated items (except if applied
directly to an image - which has implicit width). W3C's Cascading Style
Sheets, level 2, CSS2 Specifications states:
"A floated box must have an explicit width..."

They do specify it in CSS 2.1. You're looking at CSS 2. The recent
generation of browsers (Firefox, Opera, WebKit) are all aiming for CSS
2.1 plus bits of CSS 3 where they feel like it.

Ben, thank you! I would have used the auto width float DIVs anyway, but I'll
sleep a bit better now.

Enjoy,
