Sites like Glitch assume that you already have a good grasp of tech/software engineering.
The big appeal of the early internet was that anyone could make something neat with simple HTML shenanigans, and learn to code by hacking the HTML templates to their needs. Many coders got their start by hacking Neopets storefronts. (there were actual coding puzzles on Neopets too for their events!)
I think it is much easier for a non-technical person to put up a website today than in the 90s. Today you need absolutely zero coding knowledge, not even HTML.
Back in the 90s (at least in the second half) you didn't need how to code. You just used Dreamweaver or Frontpage and you got your site! The only technical bits were to use FTP to upload it to your free hosting provider.
