Lucinman:
OK I took a look at Wordpress.
Notice the if statements in the Head.php section
this is an example what they have for the IE css.
#content, #sidebar { overflow: hidden; }
.clear { margin: 0 0 4.0em 0; }
.flat { margin: 0 0 1.0em 0 !important; }
.whitespace { margin: 0 0 2.0em 0 !important; }
This is the main style.css
