I knew it was sadgirl.online. I'm wondering how sadgirl.online became so popular.
probably because of the extensive html resources for new neocities users, and it's been around for like 3 years which is relatively long on here
A lot of people have used their template generator for their site when they were learning to use html and css.
Hint: https://web.archive.org/web/20210601000000*/https://sadgrl.online Thanks to that I can always admire her masterpiece.
I'm more of a Draculuhh person myself (it's a custom theme I bodged together myself, and I use Stylus to make Draculuhh override the Ambiance theme on the Neocities editor)
Hopefully the spaghetti code on this page isn't broken, I rewrote some of it
Made the illustrations smaller since the top table would break on lower resolution screens
I seriously have no idea what theme to give that Sonic page :/
