I have a problem with positioning my text in front of my images. Somehow z-index is not working. Even if I set it to 100 the text will be placed in the background after my images.
The text appears only very quickly when loading and disappears after that in the background.

on the top left you can see "Denim Campaign for HELMUT LANG — Accra, Ghana 2020" for 1 second when loading.
