I used to be html and css-first, and to some degree I still am, but the advantages of SPA, lazy load, hot reload, and automatic state management and Dom rendering of a JS based framework are just too awesome to forego for the sake of staying native.
I know about HTMX but it's not really JS-less. It just creates the illusion that no JS is written. It still gets implemented in the browser with JS.
