Answer 1

I tested these and they're valid HTML.

IMPORTANT: Only IE 5 through 9 support conditional comments.

<!-- 1. IE 5-9 only: -->

<!--<![if IE]>
    <link rel="stylesheet" type="text/css" href="ie-5-through-9.css">
<![endif]>-->


<!-- 2. Some IE versions -->

<!--<![if gte IE 8]>
    <link rel="stylesheet" type="text/css" href="ie-8-and-9.css">
<![endif]>-->


<!-- 3. Some IE versions, plus all non-IE browsers -->

<!--[if gte IE 8]>-->
    <link rel="stylesheet" type="text/css" href="ie-gte8-and-non-ie.css">
<!--<![endif]-->


<!-- 4. All browsers except IE 5-9 -->

<!--[if !IE]>-->
    <link rel="stylesheet" type="text/css" href="modern-ie-and-non-ie.css">
<!--<![endif]-->
