Build a web template

What framework that front end web developer use to build their template or just pure HTML? Any suggestions are welcome!

Thank you!

getbootstrap is good for HTML template

Do they use React at all?

You can check their Documentation they didn’t use any React or Angular

I mean the frameworks HTML template on ThemeForest.

Bootstrap is probably the most common because it is easier for author and buyer to work with BUT there are still items sing all sorts of other options as well as some authors who have created their own solutions.
