Premade code broken like crazy?

So I tried installing code for that 3d album cover shelf thing. It's from the layout assets page. It's name is literally called Vinyl Gallery For Profile

I copied and pasted the html and css where they needed to be and made a huge chunk of bio space to separate the images I wanted to display. And I just added 2 images and it comes out broken. Like obviously my stamps shouldn't by yoinked into the stack like that. And I've seen people have stamps after it and it looks normal. And I noticed a "</div>" tag at the end of the html box and whenever I remove it the stamps don't show up.

I think I've seen the poster say it's made for space hey but it's still odd that the html is behaving like this. I also removed the from the html paste bc I already put it in the layout box, it felt a little redundant having css in both boxes.

I Just tried adding css into the bio text and it's still not working

If anyone who has used this code I'd appreciate your help
