Details
From the project READMEPlayfulness & Fun Animation
Create animations that entertain, surprise, and make interactions genuinely enjoyable.
Emotional Goal
Playfulness invites interaction through unexpected, whimsical motion. Fun comes from animations that have personality, respond expressively, and make users smile.
Disney Principles for Playfulness
Squash & Stretch
Generous, exaggerated (25-40%). Rubbery, cartoon physics. Objects should feel alive and reactive. Bounce like a beach ball.
Anticipation
Exaggerated wind-ups (150-250ms). Comic timing—big preparation for big payoff. Elements "think" before acting.
Staging
Theatrical presentation. Clear setup and punchline. Give playful moments room to breathe and be noticed.
Straight Ahead Action
Embrace spontaneity. Wobbly paths, unpredictable bounces. Characters and elements with minds of their own.
Follow Through & Overlapping Action
Extensive, bouncy follow-through. Overshoots, wobbles, and settling. Like a cartoon character skidding to a stop.
Slow In & Slow Out
Asymmetric with overshoot. Quick starts, bouncy landings. cubic-bezier(0.68, -0.55, 0.265, 1.55) for elastic effect.
Arc
Exaggerated, bouncy curves. High arcs for jumps. Squiggly paths for personality. Nothing moves in straight lines.
Secondary Action
Abundant! Wiggles, sparkles, expressions. Elements react to each other. The whole interface feels alive.
Timing
Varied and expressive (100-500ms). Quick snaps, slow anticipation. Comic timing with beats and pauses.
Exaggeration
High (30-50%). Push movements to cartoon levels. Impossible physics that feel emotionally true.
Solid Drawing
Maintain appeal through deformation. Stretched elements stay charming. Volume shifts for effect.
Appeal
Round, friendly shapes. Bright, saturated colors. Big eyes, expressive forms. Character in everything.
Timing Recommendations
| Element | Duration | Easing |
|---|---|---|
| Bounce | 400-600ms | spring(1, 60, 8) |
| Wiggle | 300-400ms | ease-in-out |
| Pop | 150-250ms | ease-out-back |
| Squash | 100-150ms | ease-out |
CSS Easing
--play-bounce: cubic-bezier(0.68, -0.55, 0.265, 1.55);
--play-elastic: cubic-bezier(0.34, 1.56, 0.64, 1);
--play-wobble: cubic-bezier(0.45, 0.05, 0.55, 0.95);
