This is the site https://wiegand92.github.io/fluffy-cat/
and I have the code available here … I think: https://github.com/Wiegand92/fluffy-cat
I also noticed that the site is a little broken on mobile. I’m sure I have some errors in my CSS declarations, but I’m still working through some trial and error on that.
Edit!!: I should have also mentioned I borrowed the code to make the modal boxes and then modified it, I’ll hunt down the original source now and post.
