Show HN: I wrote an eBook about building modern UI components without JavaScript

Hi HN,

Over the past few months, I’ve been exploring how far modern CSS can go on its own. The result is an ebook called "You Don’t Need JavaScript".

It’s a collection of UI components (animations, modals, dark mode, etc.) built entirely with CSS, along with explanations of the techniques and philosophy behind them. The main idea: use the simplest tool that gets the job done, without sacrificing accessibility or creativity.

I’d love feedback, whether on the concept, the techniques, or even the way it’s presented.
