I had to post a link to this MSDN article because its title really made me chuckle, MSDN Article - CSS Enhancements in Internet Explorer 6. Anyone who has had to develop web sites that work with IE6 as well as modern browsers such as FF3, Chrome and Safari will know what a total piece of crap IE6 and its apparent “CSS Enhancements” are.
I know it is a bit unfair to pick on old articles as computing moves so fast but if there was a Microsoft product that deserves my hatred it is You, IE6.
