You don't need PHP, Angular, React or Svelte to make things appear on the Internet for everyone to see. You can simply use HTML.
you get headers for free, but you also get a few other really interesting things!
Classic headers (h1-h6),bold, italicized, underline,
and strikethrough. I find this funny, because Jira has a hard time
with this.
If you're mathy, but don't like Latex (the text renderer), then you can do things like this:
a2+b2 = c2
Lists come for free, in both ordered and unordered varieties
MDN one of the promises of hypertext was that you could link it up to other things. This page is really just a short form of the MDN reference materials
This is wild
This is an oldie but a goodie: horizontal lines.
html also has things for <video> <picture> and
<template> so theoretically you could SSG with only
html and a little bit of js. Web-native forms are also not the worst, but
you'll never see them in production.
