Check out the image regarding the issue
I'm currently working on a page that features a fixed header with a transparent background. My goal is to make the content below this fixed header disappear when scrolled under it, similar to how it would behave if the header was not transparent.
UPDATE: I was able to solve this by applying the same background to the transparent fixed element as the body and by using the following CSS properties:
background-position: center top;
background-size: cover;
