how to make my own Online web?

Question

I know how to program in front-end HTML CSS JS but how to make my Online web?

Answer 1

You'll need to get a web hosting service such as Bluehost or Ionos but if you just want to build a static site using HTML/CSS/JavaScript and do not require SQL or PHP then GitHub Pages is a great free service https://pages.github.com/

Answer 2

+ with sql and php:
you have a lof of choices.

web hosting. you have some for free, but the most are paid services.
if you don't mind others can see the php source files, excluding the "secrets", then try vercel. on vercel I have my python-django website, but as I know, they can run php as well, but mostly designed for js frameworks.

about "how":
by uploading it to the server. it can be a `$ git push origin master` and vercel will do the build automatically.

I hope this instruction helped a little bit :-)
