CMS Image Popup (modal is contained and all images popup)

I’m trying to build a basic image pop up connected to a CMS I got the basic animation to work but its contained inside my collection item, also when I click it it pops up multiple items, can someone help me out PLEASE

edit: so I fixed the different images popping up, but the modal is still contained inside the “card” it should cover the whole page (it is set on position absolute and “full”)

Updated the link below as well

Here is my public share link: LINK

Hello, in your preview link I am only seeing a gallery. Where is the popup?

If you click one of the gallery images will popup over that image, but contained the size of the image in the gallery, it is supposed to cover the whole page, you can see it published here:

Can anyone take a look?
