Yes Mitchell, that's exactly what I'm, looking for and it's a minor change in skin.vb I think.

Lets say you want to set the background to red for one or more announcement modules:

All Announcement modules: .Module_Announcement {background-color:#F00;}

Any Announcement module in the rightpane: .RightPane .Module_Announcement {background-color:#F00;}

A specific announcemnt module: #dnn_ctr370_ModuleContent{background-color:#F00;}

Jan, what exactly do you mean?

Jan,

that's already there, assuming you have a skin.css for your portal, where a skinner can override any module.css classes or the admin uses portal.css to do the same.

Timo's enhancement would make this easier, since he introduces a naming conveinton for css classes, it would be nice, if module developers stick to it and use appropriate names for elements within their modules.
