Need Help: Z-Index not layering elements

Hello!

I am having some trouble with my z indexes. Here i want the Link block (image container) to appear between Image 24 and Heading 15. Heading 15 has a Z-index og 1, while the Image has a z-index of 5. The Link block has a z-index of 2, which should place it between right?

It did work earlier when all of these elements was in the same div (prosjekter container), but i want the Link Block to continue to scroll, when the other elements stops (sticky).

How can i make it so the Link Block appears in between the divs, while scrolling past?
Any help is appreciated.
