Horizontal - div stops moving with scroll!

Hi all, any help is really appreciated, I wasted hours on this and I can’t seem to figure out the solution

during the horizontal scroll, my div just stops moving after a certain amount, I think the problem is the CSS and sticky, but I’m not sure.

The scroll starts too early and the the div doesn’t go to the end, even though the parent section has plenty of height (you’re still scrolling through the section, but the div just refuses to move)

Any help is really appreciated! : (

Most of the time it’s a problem on the height of the parent element. Modify that to test it. And you link doesn’t work
