This applies Disney's 12 animation principles specifically to hover states, which is honestly a great framework for something most devs just wing with arbitrary timing values. You get concrete recommendations like 150-200ms for hover-in and 200-300ms for hover-out, plus ready-to-use CSS patterns for card lifts, underline animations, and icon shifts. The timing table is genuinely useful reference material. It emphasizes keeping effects subtle (max 1.05 scale) and responsive, with proper fallbacks for touch devices using the hover media query. Good for when you want hover interactions that feel polished instead of just functional.
