Transitional HTML 4.01 and XHTML 1.0 are also standards.  What I have 
done to solve Netscape's poor CSS support problem is to go back to using 
mostly HTML tags for page formating.  I use CSS for various things, but 
the page isn't dependent on it.

As a Mozilla user, and with the 90% in mind, I was tempted to ignore 
Netscape's inability to render my page the way I designed it.  I had to 
slap my self for thinking that way.  And since CSS isn't fully supported 
on some browsers while HTML 4 usually is, it seems logical to do most of 
my formating with HTML.  Problem solved.

Compatibility awareness is one of the reasons I like PHP and avoid 
JavaScript.  I'm sure there are some people here who can relate to that.
