I've realised that I came across some very good articles on web design, and formatting issues across browsers. I'm gonna put them here in the next day or so. Currently the links are on my work computer, which I'm away from right now. The only one I can think of right how is Mako's guide to CSS, which covers a wide variety of issues, particular CSS support on Netscape 4 browsers. I know, NS4 is not exactly popular these days, but there are even more up-to-date browsers that don't support all of CSS2 yet, and some people will never upgrade!
