IE Hacks
The following conditional comment is being picked up by IE5, IE5.5 and IE6:
<!--[if IE]> <link rel="stylesheet" type="text/css" href="all-ie.css" /> <![endif]-->
The !ie identifier allows the property to be applied in IE 7 and below. It may or may not work in future versions. Warning: this uses INVALID CSS!
Example how to use this IE hack:
.bluebox-area {
width: 175px;
height: 50px;
top: 25px !ie; /* IE HACK for IE7 & BELOW */
}
