No, HTML5 is a markup at the end of the day. Comparing JS and HTML, is like
comparing apples to oranges. All HTML5 does is include new tags to use when
building a web app for you or search engines to use:
https://www.w3schools.com/html/html5_intro.asp. It doesn't at all handle
any logic like JS would, if that's what you are asking.

Same can almost go for CSS. It's a description language, it doesn't handle
any logic (except for select queries). However, CSS is starting to
implement variables, but you can only use those for *attributes*. Not write
a fully functional app with CSS alone.
