If you use this HTML: <!--[if IE ]> <body class="ie"> <![endif]--> <!--[if !IE]>--> <body> <!--<![endif]--> with CSS that looks something like: div.foo { color: inherit; } .ie div.foo { color: #ff8000; } then you get all of the advantages of using conditional comments to work around problems in Internet Explorer, without the extra HTTP request of an IE-only stylesheet. ■
