How would you host a website that was made from HTML and CSS

Okay, so I made a few static projects with HTML and CSS, one specifically that a friend is willing to pay for, but I have one issue. I have to idea how to actually get it up to be usable. I'm actually not sure of the term (Deploy or Host) Right now, I'm using stackblitz from github since it allows for multiple pages.

I could've also used webflow but... I would still need to know how to get one I made from scratch up and running

Edit: Thanks for all the comments and suggestions, everyone, really appreciated. I'll definitely do a lot of research on all of the options you guys gave.
