There's https://tailwindui.com/?ref=top, from the Tailwind CSS people. They come with a "HTML" mode, which I think means no JS.

But if you need interactivity, on the web it has to be JS, because that's the only thing that can manipulate the DOM. (Edit: To be clear, there are frameworks that COMPILE to JS, so you the programmer don't have to work in JS yourself.) The alternative would be something like a server-updated Canvas where the UI is done outside of the DOM and not in the client, but even that would need some JS shims just to communicate and redraw the Canvas.

If you want to render the entire page serverside and handle all interactions via clicks and HTTP POSTs and such, you still can, of course. That would just be slower for the visitor.

Probably a "JS-lite" approach like HTMX + Alpine would be worth considering?
