Z-Index of 0 = bottom layer
Z-Index of any other number = the layer it is on
So the one with the highest Z-Index value will be the top layer
***Edit as mentioned by @ilikewebdesign : The element position must be set to either Relative, Absolute or Fixed in order to modify the Z-Index
Cool! Makes sense… which button is that in the Designer UI?
Nevermind… I found it! It’s under the Position tab at the very bottom-right. You do have to enable the Advanced tools though…
The position also has to be set to something other than Auto…
Yes z index only effect elemets that are set to something other then static, which is auto. So anything that has relative, obsolute or fixed positioning
