ehem.. I feel sooooo stupid. I'm not going to explain why, but the thing is that yesterday I did it wrongly, and it didn't really work.
Finally I wrote the url to the css -->
http://whatever/styles.css and netscape told me that what I was about to download was a aplication/x-pointplus MIME type.
As the guys at devedge say: (
http://devedge.netscape.com/viewsource/2002/incorrect-mime-types/)
"Many Web servers have incorrectly specified MIME types for files. Netscape Gecko browsers require that the server specifies the correct MIME type to match the content type: HTML - text/html, CSS - text/css, XML - text/xml.
The W3C specification mentions that CSS files should be served with a 'text/css' MIME type. Mozilla and Netscape 7.x, when used in 'strict mode' will follow the specification closely and expect the CSS file to be served with a correct MIME type ('Strict mode' is enabled by having a strict DTD mentioned in the first line of the HTML page). In 'quirks mode', both application will tolerate the wrong MIME type and use the attached style sheet despite the incorrect server configuration. This means that you cannot have 'Strict' documents with a misconfigured server. MSIE lets you get away with this misconfiguration by incorrectly not taking care of the MIME type provided by the server in the http header"
I'll keep informing on this subject. What happened after asking the server administrator to change the MIME type to text/css is so extrange that I prefer to wait until things get clear.
