The main difference I run into time after time is the CSS needed in 
bulleted lists to control the size of the indent and the position of the 
bullet.  According to the CSS2 specs, different browsers can control this 
differently:  and they do.

For example, in my Browser News site, I use this CSS for IE6:

     ul li { margin:0 0 0 2em; }

Whereas for Opera 7 I use:

     ul li { margin:0 0 0 1.5em; }

And for Gecko browsers I use:

     ul li { margin:0; }

These don't produce identical results in the Browser News site, but they do 
produce comparable results.

The CSS2 specs do define 'markers' which could be used to control 
positioning in a browser-independent manner, but no browser has ever 
supported them, and indeed markers have been dropped in CSS2.1.

As to why I want to control the size of the indent and the position of the 
bullet:  I simply want bulleted lists that are more compact.
