What is the best way to implement custom CSS classes in custom modules?  I have text that I want the user to be able to reformat - but I don't want to use existing classes for maximum visibility.  Up until now I have been putting these class values in <STYLE> tags on the designer code, but what I would like to do is have my module have a CSS file of its own for default settings, so that a user can override it at the site level, or even the skin level...   Also to help keep my development a little more organized.... 

Any suggestions would be quite valuable,

Thanks!

Thank you - the module developer doc wasn't completely clear on this - it referenced module css but only talked about a naming scheme to use.  - I put a modules.css file in my module directory and everything is working as expected.
