Hi techunar, Conditional comments are useful and clean way to apply a different stylesheet depending if the browser is IE or not. This condition only loads a different stylesheet (style_ie.css by example) if the browser is IE (in general or any particular version), but if its not, loads the default stylesheet (style_all.css by example). Here you can find a lot of examples: http://msdn.microsoft.com/en-us/library/ms537512.aspx Hope this was clear and helpful for you
