Lottie · FAB

A floating action button that morphs open — Lottie JSON. Lottie JSON from spemer/lottie-animations-json (MIT). Part of motion-anything; obeys MOTION-SPEC.md.

When to use it

• Portable JSON motion identical on web & app; icon/control micro-animations (incl. After Effects / Jitter exports).

When NOT to use it (restraint)

• When a pure-CSS effect would do — don't ship the Lottie runtime for a simple fade.

How to apply

1. Include lottie.min.js (runtime) and animation.json.
2. lottie.loadAnimation({ container, renderer:'svg', loop:true, autoplay:false, path:'animation.json' }); start on intent / guard reduced-motion.

Accessibility & performance

• prefers-reduced-motion: don't autoplay. SVG renderer; motion-as-JSON (portable, AI-readable).
