There are two possibilities for this problem.

1. Either the CSS file is missing and your system is serving up a 404 page (if you've configured it) so the browser is complaining that it's not a CSS file.

2. It could be that you have a server configuration issue. If it's a new installation of WAMP, this is pretty unlikely.

Just to validate the stuff, you can view the source in any browser.

On browsing CSS file, if it takes you to another file that means you haven't linked it properly. You may be better off using an absolute path (from your webroot) rather than a relative path.
