Thanks, what i mean is that now i have a background with concrete look, and white in the middle. But when you scale down the size of the screen, the concrete look should go away and only the white should appear. on mobile and on smaller screens it looks strange. https://gyazo.com/ecde485850dc40882317846d83a77280
