To build an application a framework was always a requirement. Developers either used an existing one or created their own. And I believe it is true for any application development, the code you see in tutorial or courses are not the same in a professional environment.

Same goes for HTML/CSS/JS, in fact, CSS and JS are the answer to the limitation of HTML and static page serving which was the vanilla www. As for your question, I don’t see HTML/CSS/JS going anywhere, they are the building blocks of web development and are written as such.
