I was wondering how I would make a tab in the coding? I've tried using html/css but it doesn't show up? I wanted to use it to put different parts of the story for my pet (like chapters) + credits

I've been trying to use a code like this but no matter what I do I can't make it work. (This is just the base example from w3schools)

is this what you're trying to do?

Yeah sort of! I can use this though thank you very much!
