Background Size

[verbal prawn]

Hey guys, I was working on this blackjack game project which is going fine but I am stuck with the background-size whenever I switch to smaller screens background leaves whitespace in my body, I tried to do background-size: cover but it didn't work. So please suggest me some solutions.
