I recieve a fair number of emails asking about SharePoint Portal Server 2003 customization. Here is the readers digest version on one possible way to go about things.
SharePoint Portal Server 2003 uses OWS.CSS MENU.CSS and SPS.CSS by default. If you are looking to do ‘global customization’ within SharePoint Portal Server you are definately encouraged to leave the SPS.CSS alone.
What you should do is duplicate and rename it. Once you have made a copy of your SPS.CSS file you can then customize the style-sheet to your liking, when happy with it you can simply point to this Custom CSS file.
To point SPS 2003 to a custom CSS file point your browser too:
Rather than regurgitating all this information I will do what I normally do when asked “How can I get a quick jumpstart on customizing Portal Server?”
I will point them to Bil Simsers great post on SPS Customization
I guess it’s warrented to get a little more in-depth with the SPS Customization posts real soon.
