CSS comes in 3 Levels and probably the best way to understand it is by taking some time on this link.

I find W3Schools very useful.

the position proerty allows you to specify the number of pixels left/right/up/down you want an element to appear in its containing element. Its used to position most things on the page. Z index refers to what appears on top of other things, creating sort of another layer, coming out of the page. :D
