Motion with meaning: a practical taxonomy

3D & MotionJune 30, 20267 min read

We sort motion into orientation, feedback, continuity and delight. Anything that doesn't fit a category is decoration and gets cut.

Durations: 120ms for feedback, 240ms for continuity, 400–600ms for orientation. Delight can be longer but must be interruptible.

Always honour prefers-reduced-motion by swapping transforms for opacity, never by removing the state change entirely.
