How I can fix the position to stay in the same position on mobile version

Hi,
I’m super new on webflow like 101. And I really need help!
How I can fix the position to stay in the same position on mobile version?
I might set up something wrong on the destop vertion like to make the BG image to shrink down when adjust the screen (I just followed youtube)
