Is there any open source/free CSS-style generator. What I am looking for is to be able to apply styles through UI, see a preview of styles applied on an element and when I am satisfied, get the CSS code generated for that combination.
http://www.csswizard.net/ also you have demo and tutorials there, you can add elements, edit code... have a try. This one still requires registration but this is in case when you need more templates or more functions, otherwise it might be a good software to work with.
