I browsed sitepoint.com with NS7 and IE6 and I'm surprised to see that sitepoint seems to be using the same stylesheets on these two browsers keeping the same font size although font size are defined with "small, x-small, xx-small, ..."

(only moz.css is added for NS but there is nothing related to font size on that .css file)

When I do this on my site, I have to create different stylesheets for NS and IE otherwise fonts are displayed smaller on NS.

How do you do this ?? O.o
