Can you please help me clarify? If we have some multi-level structure, f.e.
.div-1
.div-2
.div-2
.div-3
It's impossible to hide .div-3
behind .div-1
using z-index
in anyway? We can manipulate layers on same level of DOM? Is it correct statement?
Then how do we make layouts where we want an item of .div-3
hide behind main app layer .div-1
? Let's say we have a closing button of .div-3
that we want to roll out of (from beneath) .div-1
?
If I have explained poorly, I will clarify.
