Hey Bas,
I haven't personally used the parallax component but the first question that comes to my mind is why adding it to the main div which might be source of the issue.
It is also very difficult to give an accurate answer without being able to inspect the page HTML.
Cheers,
Thx Thierry, I choose the main because I want eveything to go over hero/header image. But as I do not have expereince with parallax there is probably a better solution.
