You are right I should give it a try. I’m newbie to this so I would be very happy if you would like to guide me.
Should I replace my code with yours or add it?
If I add “background-size: 100% 100%;” will the image not cover the whole screen then?
My previous code I put in the custom stylesheet for my background image set, is the where I should put your code?
Sorry for my poor skills and thanks for your time.
