Ok sorry, was going by what the stylesheetmaker told me to do.. I guess it's really outdated lol :
It's not so much that it's outdated, but it's set up to create an internal stylesheet, - the kind you place in the <head> section of your html page.
But, of course, you knew that from the link I posted for you before: http://www.w3schools.com/css/css_howto.asp
(There are only a dozen lines or so to read and they explain it ALL!)
