Here's the thing: despite what JS fans will tell you, you can make visually appealing, quick-loading, useful page/site with just HTML+CSS(+images/svgs etc) client side.
You don't need JavaScript.
The reverse isn't true. You can't make a page out of just JavaScript. Even if JS builds your DOM and builds the styles for it (because hey, crazy people have crazy ideas) the DOM and styles are still HTML + CSS. You still need to know what the JS should build.
