Look at “Nav Z-Index Issue” page:
I would like to have a slim header area above the navbar. In the header area, I’d like a logo centered, and positioned negatively so that it overlays the navbar (where I’m going to create two nav menu wrappers so I can position to menus left and right, leaving room for the image overlay.)
Here is a screenshot:
Seems like everything I tried (setting z-index, relative, abs, etc.) has the same effect as appearing under the navbar.
What say the experts?
