I have a fixed div overlay (whole screen) which contain another smaller centered div for a message.
The big div has position:fixed and opacity.
The inner div also has position:fixed but without opacity
But in the inner div , I don't want to have any transparency.(opacity: 1) :
Problem:
I still see it as transparent. How can I fix it ( the inner div) ?

the inner div background-color is black. and the color is red. and (as you can see) it is not what is happening. ( I also tried !important)
NB
the overlay div and inner div should not be scrolled when user scrolls.
