Use when creating animations that evoke happiness, surprise, or delightful moments in the user experience.
Create animations that spark happiness, pleasant surprise, and memorable delight.
Joy emerges from unexpected pleasures, playful movements, and moments that exceed expectations. Delight comes from animations that feel alive, responsive, and genuinely fun.
Exaggerate bouncy, elastic movements. Objects that squash 30-40% on impact feel alive and playful. Use for success states, rewards, and celebrations.
Build excitement before reveals. A slight pullback (100-150ms) before a pop-in creates satisfying payoff. Perfect for notifications and achievements.
Draw focus to joyful moments. Clear visual hierarchy ensures the delightful element gets full attention. Dim surroundings during celebration animations.
Create spontaneous, organic movements for confetti, particles, and celebration effects. Randomized paths feel natural and exciting.
Let elements overshoot and settle with bouncy secondary motion. Hair, ribbons, and decorative elements should continue moving after main action.
Use asymmetric easing—quick starts with slow, satisfying landings. cubic-bezier(0.34, 1.56, 0.64, 1) creates playful overshoot.
Bouncing, curved trajectories feel more joyful than linear paths. Elements should travel in parabolic arcs during celebrations.
Add sparkles, particles, or wobbles to primary animations. A "like" heart that radiates small hearts amplifies joy.
Fast, snappy timing (150-250ms) feels energetic. Quick bursts with micro-pauses create rhythm. Success animations: 200-400ms.
Push proportions and movements 20-30% beyond realistic. Oversized bounces, stretched smiles, and amplified reactions.
Maintain volume during stretchy movements. Squashed elements should expand horizontally to preserve mass—this reads as physicality.
Round shapes, bright colors, and smooth curves. Asymmetry in timing and position adds character and charm.
| Element | Duration | Easing |
|---|---|---|
| Pop-in | 200-300ms | ease-out-back |
| Bounce | 300-500ms | spring(1, 80, 10) |
| Confetti | 800-1200ms | ease-out |
| Celebration | 400-600ms | ease-out-elastic |
