[Plone-UI] Custom CSS for different portlet types?

All, thanks for your responses but i AM developing on the file system. I have
change the portlet code because A, the method i am using for rounded corners
is different from how Plone does things. B, the method i am using is much
simpler using divs instead of dl's, dt's, etc etc.

Instead of using custom css for every portlet color, i figured it would be
easier to call the css and just switch out the single image i am using for
the rounded corners depending on the portlet i am in (news, rss, etc) . You
can find the method i am using here:

Oh, and implementing rounded corners WITH transparent curves is not a
trivial thing in the standard build-out of plone. i have a gradient
background and need rounded corners to look properly. So, many of the
methods that exist out there that have 'rounded corners' work ONLY if you
background is solid that the corner resides on. The above method is the one
i found that works quite nicely

Veda, thanks for the info on the links and tutorials, i have poured through
those, i have about every plone/zope book out there (waiting for yours to be
available) and i 'get' the file system development.
