Just finished rebuilding a personal website , pretty normal just a link aggregator I guess and I have got over 160 lines of vanilla CSS but only 15 lines of JavaScript. Is this normal lol ? I think I focus too much on design and "aesthetics" .

160lines of css is just enough to center two divs, and you can go with no js and be fine

I mean, in the end of the day, your site is converted only by looks and content (and probably some a11y considerations). Everything else is extra.

I use JS powered tool (11ty) to minimize JS on the site to almost zero.

Still too much JS but i don't want to optimize too early! XD

I made career out of JS but I said it before and I'll say it again: the less JS you have in the codebase, the better!
