Help how do I do anything custom? :( I don't know how to code

HI, NON BLOGGING ABT LIFE POST THAT COEMS TOMOTTOW

so basically, I wanted to make my profile based off of Bendy and the Ink Machine, aka the game I'm hyperfixating on rn and that I'm playing while I'm typing this. I could not find anything from the layouts section, so I tried to make my own, following a tutorial and posting the images I wanted to use on imagur... And it didn't work. I don't know HTML or CSS for the life of me, so any advice, or visual guides, or any copy and paste customizing would be helpful, thank you
