How did I make this website?

Honestly, I just asked google how to make a site work, I copy-pasted some things that came into the results and used what I remembered from my programming classes at highschool... not my proudest statement.

I also typed some things manually. Just like this paragraph. If there's something here that you like you can copy it. Just make it slightly different, and tag me. (Can you even tag in this website??)
