Best practices for layering multiple images?

I want to recreate this animation here: https://www.loom.com/share/472b9ac3cd074ab39e91f7653a368b4f

My problem is not so much how to create the animations, but how to layer them and make them stay where they’re supposed to (while being responsive) without it getting so messy. I understand the z indext part. I just don’t know how to go about making them overlap. I’m assuming it has to do with negative margins?

Is there perhaps a video tutorial where someone makes an animation similar to this? One with many images stacked on top of each other? That’s how I learn best.
