Modern CSS features like content-visibility, container queries, and scroll-driven animations now handle tasks developers traditionally solved with JavaScript. Content-visibility provides native virtualization without libraries like react-window, container queries enable responsive design based on parent containers rather than viewport width, and scroll-driven animations run on the compositor thread for better performance. While JavaScript remains necessary for truly infinite lists, precise measurements, and dynamic layouts, most common use cases benefit from CSS-first solutions with simpler code and better performance.

When to stick with JavaScript workarounds

Is your frontend hogging your users' CPU?

I like that the article said.
CSS isn’t always the answer. There are unique cases where JavaScript is still the right tool, and pretending otherwise is dishonest.
But yes. We should rely on CSS whenever possible and applicable before using JS

Solid article. Many developers are still unfamiliar with modern CSS capabilities, which is why they often resort to using JavaScript to solve issues.

Nice, and the examples are gold.
Now with the if() the sky is the limit.

You had me as “Stop using JavaScript.”

I can’t agree more. I in fact wrote a book on that same subject if you are curious: <a href="https://theosoti.com/you-dont-need-js/" target="_blank" rel="noopener nofollow">https://theosoti.com/you-dont-need-js/</a>
