Nothing, but it’s not a programming language

What is it actually then?

It’s a markup language. In the simplest explanation, a programming language describes a process (what does the thing do) while a markup language describes a structure (how is the thing supposed to be displayed). There’s more to it than that, but someone else can get into deeper if they want, it’s beyond me lol
