How to make a light and convenient lightbox with gridify?

[ArsenalLoko]

Hello. Two questions

1. How to make photos open to full screen when pressed. I try different popular lightbox/lightgallery etc, but none of them work inside the grid--items class. If I specify the lightbox class earlier, then yours does not work. Please tell me how to correctly add photo viewing to this code of yours. It is comfortable and weighs little, which is important.

2. When the page with griddify images opens, the original image opens very quickly to the full screen and after loading the code everything works fine. I checked that you have the same in the demo. I solved it by delayed page loading via data-aos-duration="2000"

Sorry about my English. I'm not a programmer, so some moments I'm like a beginner
