Lottie · Tab
An animated bottom-tab indicator — 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
- Include
lottie.min.js(runtime) andanimation.json. 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).
