CSS Conditionals (Conditional Comments) for Internet Explorer

"Several CSS hacks failing. If you are using IE7 (you are MSDN subscriber or received a copy at the PDC) you may notice major sites breaking due to the use of CSS hacks and the strict doctype. "

" The browser type can be detected using many different techniques. Most methods of browser detection make use of either server- or client-side script, and each have advantages and disadvantages. This article focuses on conditional comments, which offer an alternative to scripted browser detection. Conditional comments offer certain advantages over scripted browser detection techniques and are also easier to use.

Conditional comments have been available since Microsoft Internet Explorer 5, but their use is not restricted to Internet Explorer. Examples are given that show how conditional comments can be used to customize the content delivered to both uplevel and downlevel browsers. Conditional comments make it easy for developers to write pages that downgrade gracefully in less capable browsers, while making it easy to take advantage of the enhanced features and performance offered by Internet Explorer 5 and later versions."

<!--[if IE 5.0]>
<p>Welcome to Internet Explorer 5.0!</p>
<![endif]-->

However, I put the following code into my css file:

<!--[if IE 5]>
<SCRIPT LANGUAGE="Javascript">
alert("Congratulations. You are running IE5 or later!");
</SCRIPT>
<P>Thank you for closing the message box.</P>
<![endif]-->

http://www.positioniseverything.net/articles/multiIE.html has a particularly good way to target Conditional Comments to e.g. IE 5.5
