I would like to have something that looks nice and modern, has a good user experience, and is responsive. Those three requirements take me pretty close to the "too ahrd" rabbit hole most of the time. Not always, just often enough.

Apart from one or two things that are currently not implemented well by the browsers, your requirements can be met without a single line of JS or even a server at that. And you may very well not run into those one or two things.

Could I ask you to elaborate futher?

I dont see how a single line of js can remove the need for front end design, complexities of scaling, theme choices, and user friendly design patterns with interactivity.
