Joy Delight

A practical reference for adding personality to your UI through animation, organized around Disney's 12 principles. It gives you specific timing values (200-300ms for pop-ins, 300-500ms for bounces), ready-to-use CSS easing functions with overshoot, and guidance on when squash and stretch actually makes sense. The framework helps you think through success states, celebrations, and reward moments systematically rather than guessing at spring values. Best used when you're building confirmation flows or achievement systems and want them to feel genuinely satisfying instead of just functional. The timing recommendations table alone will save you from the usual trial-and-error with cubic-bezier curves.

Joy & Delight Animation

Create animations that spark happiness, pleasant surprise, and memorable delight.

Emotional Goal

Joy emerges from unexpected pleasures, playful movements, and moments that exceed expectations. Delight comes from animations that feel alive, responsive, and genuinely fun.

Disney Principles for Joy

Squash & Stretch

Exaggerate bouncy, elastic movements. Objects that squash 30-40% on impact feel alive and playful. Use for success states, rewards, and celebrations.

Anticipation

Build excitement before reveals. A slight pullback (100-150ms) before a pop-in creates satisfying payoff. Perfect for notifications and achievements.

Staging

Draw focus to joyful moments. Clear visual hierarchy ensures the delightful element gets full attention. Dim surroundings during celebration animations.
