how to create a website to be interactive?

Answer 1

An interactive website, in programming, is meant to be a website that uses JavaScript as it's also called "the language that makes a website interractive" but I know you did not mean that.

I think that you were talking about how it looks (CSS). Bootstrap is a great, quick way to make a website interractive and beautiful. In order to make a website even MORE intereactive, you will need to learn Marketing at university or Online. (It highly depends on what are you after.

Have a bug-free coding and next time post questions that may have a clear ansewer, going right to the subject.
