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" .

nah, not normal.

too much javascript. try getting it down to zero.

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!
