I tried this but it didn't work.

Hi!
The conditional comment (like <!--[if IE]> ) only applies to IE.

"IE-based browsers like Maxthon and Avant handle them like Internet Explorer does while browsers using other layout engines see them simply as regular comments. Internet Explorer on the Mac uses a different layout engine and doesn't support conditional comments."

I think you need to check browser with javascript and output accordingly

what you do is simply choose the IE conditional test at the beginning, and if it is not IE, you run the rest of the code for all other browsers --

if IE -- do this ...
else .... do this ....

Remember, you will need different code for IE6 than IE7 in many cases.  IE6 is the least compliant, so do --

If IE6 then do this
else if IE7 do that
else do the rest.

The problem with your solution scratcyboy is that other browsers still treats conditional comments as regular comments.

<!--[if !IE]> and <!--[if IE]>  <![else]>  is therefore pointless IMO.
