Is it possible to hide a child element behind the parent using z-index?

Question

css

There is such a layout
As you noticed quotes behind the main element, that is, I created these quotes inside the main element and attached them to the top left edge with an absolute, I gave the parent z-index : 10 and even tried to give the quotes minus values, and the result is like this
they don’t want for the parent at all hiding, and here the question arises, do child elements inherit the z-index value from the parent? Okay, after the parent quotes I defined z-index: -2 ! HELP!

Answer 1

As already noted in the comments - you do not need to set the z-index of the parent, because then you will not be able to kill it from the heir. Just set the z-index to the absolute block and you will be happy.
