Thread:Project:Support desk/I need help customizing the sidebar in Vector.css

I recently changed the skin for http://en.sturmkrieg.com with the Vector.css page with code from another Vector wiki as a guide. However, the sidebar at that wiki was setup differently, without collapsable tabs, and so there's an issue at Sturmkrieg. How can I set the Vector.css so that the names of each section aren't blue and they are a different color when the section is expanded?

Also, how to I stop there from being lines under the subsection titles and change the lone horizontal lines back to black?
