Eg: to minimize errors in IE, Microsoft has implemented conditionnal comments in their browser, which allow you to link a style.
<!--[if IE]>
<link href="ie.css" rel="stylesheet" type="text/css" />
<![endif]-->
You can also target only a certain version of IE:
<!--[if IE6]>
<link href="ie.css" rel="stylesheet" type="text/css" />
<![endif]-->

<body>
