I am having problem in CSS and HTML not working in Firefox and Opera but working good in Internet Explorer.

Awaiting solution.

Can you explain what is not working? And if you can give us a link to your site rather than posting the code here, that will make it easier for someone to help you. (Posting the code does help some, though.)

I have the same problem - the website I was working on works fine in the older Firefox 3 and it works with IE, but not Firefox 4 or Chrome. Here is the website:

Any help or advice would be greatly appreciated!
