[Mediawiki-l] change position navigation bar

[Rein]

I would like to lower the logo a bit.
No problem.
But the navigation bar stays at the old position. It has apparently also an absolute position.
But nowhere to be found.
In the instruction page it says that it is managed with p-navigation in CSS.
But there is not such a thing in the whole wiki except in an CSS fix for Explorer.
There is even no sign of possible absolute positioning either on wiki.
Who can solve the mystery?
