Make backgrounds color on section stay still instead of moving with scroll

Recently i made a gradient background for my shop with the top of it being transparent, i found that the color keeps moving with scroll instead of standing still. I was told by support that it might have something to do with my custom css background image. Any suggestion are appreciated

Hi, @Andrej101

Can you share the store URL and take a screenshot to describe your requirements? So that I can assist you.

This is how it looks like when it is scrolled down. However, scrolling a little bit upwards causes the color to go up with the page. What i want for it is to just stay still so that it looks like the first picture all the time

The problm is that the color moves together with the scroll, i want it to just stay still so that it always looks like the second picture but i can’t seem to find the right code for it unfortunately
