This translates Disney's 12 animation principles into practical frontend code patterns. You get specific CSS and JavaScript techniques for each principle: when to use scale transforms for squash and stretch, how to stagger delays for follow-through, which timing functions feel natural. It's opinionated about performance (animate transforms and opacity, avoid layout properties) and includes accessibility reminders like prefers-reduced-motion. Use it when you know an interaction needs animation but aren't sure how to make it feel good. The implementation checklist and timing standards (200-300ms for UI feedback, 100-150ms for hovers) are immediately useful references.
