z-index property not work

Question

Hi man I have following codes, and I wont to that when I\'ll click some button fadeTo only content without #some tag
In this case fadeTo<

Answer 1

I could be wrong, but im fairly certain that BOTH elements you want to include in the z-index must have non-static positioning.

So if you made your #content and #registration,#login non-static elements, it should work.
