Hi

I was looking at the source code of a site which had the code below in the
<head> section.

Could someone please explain whether this is a known and effective way of
compensating for browser CSS bugs, and if so, how it works?

Thanks,

Jeremy Clulow

<style type="text/css" media="screen">

<!-- /*<![CDATA[*/ @import url("standard.css"); /*]]>*/ --> </style>

 <!--[if IE 5]>  <style type="text/css" media="screen"> /*<![CDATA[*/
 div.storybox { top: 100px;}
 #header .logo { margin-top: 10px; }
 .item { width: 48%; }
 #menubox { width: 200px; }
 #submenu li { margin: -1.1em 0em; }
 #submenu { margin: 1em 0em 0em 0em; }
 /*]]>*/ </style>
 <![endif]-->

 <!--[if IE 5.5000]>  <style type="text/css" media="screen"> /*<![CDATA[*/
 .logo { margin-top: 10px; }
 .right { border-top: 10px; }
 .item { width: 48%; }
 #menubox { width: 200px; }
 #submenu li { margin: 0.2em 0em; }
 #submenu { margin: 1em 0em 0em 0em; }
 /*]]>*/ </style>
 <![endif]-->

A CDATA section is an XML construct, if you find it in a HTML page then
probably as someone tries to author XHTML. If you find it in the
complicated way you have posted then someone probably tries to author
XHTML that can be sent to HTML user agents with content type text/html.
As that is all tedious, cumbersome and error-prone it is usually best to
simply author HTML 4.01 and not XHTML 1.0, see
  http://www.hixie.ch/advocacy/xhtml
for instance.

I don't think a CDATA section helps to hide CSS from certain browsers.

Those are Internet Explorer "conditional comments". They're a
Microsoft-only hack:

Thanks for that. It looks interesting.
