One toggle. Infinite expressions. JavaScript flips the switch. CSS does the choreography. Logic lives where it should. Style dances where it belongs.

From state to style. Toggles trigger change. Transitions make it beautiful. This pattern keeps your components readable, portable, and refreshingly sane.

Copy. Modify. Ship. Zero dependencies. Zero libraries that ghost you after an update. Framework-agnostic code you can actually call your own.

CSS transitions live on the GPU, running buttery smooth even when your event loop is having a moment. Built this way, your components are faster, leaner, and surprisingly bulletproof.

States belong in CSS. Styling stays separate from logic. Your designer can fine-tune easing curves without hunting through your JavaScript.

When the bundle fails, your styles don't panic. The experience gracefully degrades instead of face-planting. That's CSS-first resilience.

Ready to ship. Copy it, tweak it, own it. Lightweight components that give you total control without the dependency circus.
