Find every second(third) element in Angular?

Question

css

Good afternoon everyone!
I display cards on the main page through *ngIfeverything is fine, but I need to make an adaptive and here is the most interesting thing. when you click on the card, a modal appears (it is attached to the card, set top: 0 left: 0), but when I reduce the screen, the modal goes beyond the view screen and a scroll appears! is it possible for me to define every second third and so on element through css?
tried to use :nth-child(2n)does not work.
It is necessary that if not a small screen, a window does not appear on the top left and top right!
I so suspect only through js to do?
