Consider the following example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<style type="text/css">
div { width: 15em }
input, textarea, select { width: 100%;
-moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box }
</style>
</head>
<body>
<form>
<div>
<input value="Input">
</div>
<div>
<textarea>Text area</textarea>
</div>
<div>
<select>
<option>One</option>
<option>Two</option>
<option>Three</option>
</select>
</div>
</form>
</body>
</html>
On browser that support the border-box box sizing, this is rendered as I want:

On IE 6/7, however, this is rendered as:
IE 6/7 rendering http://img.skitch.com/20100522-f5pkgnwwceaak3t8fqq2w16gfm.png
How can I get the same rendering in IE 6/7 that I get in other browsers, without resorting to setting sizes in pixels?
This is not possible with CSS. I did some research and I found out that the same question was asked before here. The solution is to use this boxsizing.htc file and add the following line to your HTML head:
<!--[if lt IE 8]><style>input, textarea { behavior: url("boxsizing.htc"); }</style><![endif]-->
