What does Header Setting > Scroll Effect: Fade Out > Overlap do, Looks like not working

Question:
Question about Header Setting > Scroll Effect: Fade Out > Overlap

I am new to Wix Studio and trying to learn it.

  • I am working with Wix Studio site template - One Page Responsive > Law Firm > Jake Evans
  • I am new to WIX and I’m trying to learn from the templates. In the header properties there is overlap option for the scroll effect fade out and it’s either none or next section.
  • I do not see what it does. I try both options to see how the header reacts differently to the scroll and I don’t see any difference.

The help says “Overlap: Decide whether or not the header overlaps the next section while scrolling. If you set it to not overlap, you can set a top offset to create some distance between the header and the top of the page.”

but I don’t see it.

  • A second question - Is the whole purpose of the overlap only in terms of the scroll effect, or is it also have to do with the background of the header?
