Dear People!
My CSS (especially those for my menu (ul, li, a)) suddenly affects the appearance of the buttons of my edit bar. For instance it is not possible to create blue menu buttons, without turning the white buttons of the edit bar to blue too. When I want my menu-buttons to be 100 pixels high, the buttons in the edit bar does the same. The same with the color of the font.

It ist not possible to work on the dashbord or anywhere else in the backend.

Does anyone have a tipp?
Thank You

Mathias
