Input over positioned div

[PHPstarter]

Hi guys.

Just wanna know if this is a known problem for anyone.

I have placed some background images as divs using css and positioning.
They are all placed with relative.

Over them, I have input buttons, what are links for navigation. But they don't work as long as they are positioned over the DIVs there.
This happens if they are assigned with position relative or nothing.

I think I fixed it.. Had to put the buttons in a seperate div in another location.. Lead to some more work aligning the background but it works so far.

Thanks
