It is a shame but CSS2 is still not supported enough... especially by netscape. However, CSS2 and CSS3 when they come out will make browsers more graphic and layout friendly. Still, there is the problem of printing... one that has never really been covered by the browser manufacturers. Netscape, for example, will adjust the layout of a page so that layers don't overlap before printing it and, in both cases, the quality of the printing is too low for graphics. This makes it very hard for people who want to design interactive, graphics based programs for the net.

If I sound disgruntled its because i spent about 2 years doing exactly that... and never quite got the results I wanted :P
