Why isn't my IE6 Conditional stylesheet not working?

This is driving me nuts. I'm trying to use a conditional IE6 stylesheet. I posted this test page here. Here is the code I placed in my head tags:

<!--[if IE 6]>
<link rel="stylesheet" type="text/css" href="ie6.css" />
<![endif]-->

The ie6.css should set the body background to red when viewed in IE6.

What's wrong here? I'm sure it's something dumb. Could someo开发者_JAVA百科ne please point it out to me?

It works fine for me. Run your test page through IE NetRenderer and you'll see the red background. Perhaps you're testing it in a version of IE other than 6?

You don't happen to be trying this using IETester?

Because with IETester, Conditional Comments will always resolve to the highest installed version of IE.

is the CSS file in the root folder (same folder as the HTML) ? it's good practice to put your CSS in a separate folder.

<!--[if IE 6]><link href="css/ie6.css" rel="stylesheet" type="text/css" /><![endif]-->

I just had a similiar issue. The conditional comments did not work correctly and I tried everything. The issue was that I had an X UA compatible meta tag in the header which obviuously influences the rendering. So keep watching out for that because that can be a reason.

<meta http-equiv="X-UA-Compatible" content="IE=7" />
