How to make this lightbox

Hello,
I am trying to create image galleries, where the lightbox occupies all the visible part, without thumbnails or texts, but I don’t see any option in this regard in webflow.
Something similar to what is my old photo page!
thank you

Here are some images about, an a link to my old web: Personal - Santi Gili
