Easiest option - set .wrapper already prepared the background
For-harder - .wrapper position: relative;, the child elements specify position: absolute; (top, right, left, bottom, - 0), and then
The right side should be a slider, so as to solve the problem?take the wrapper that is with photoshop? - Deon98 commented on July 8th 19 at 16:27
