Feedback Indicator Animations

Apply Disney's 12 principles to action confirmation animations.

Principle Application

Squash & Stretch: Success checkmarks can scale with overshoot. Compress on draw, expand on complete.

Anticipation: Brief gather before feedback appears. 50ms of preparation before the confirmation.

Staging: Feedback appears at the action location. Button shows checkmark, field shows validation.

Straight Ahead vs Pose-to-Pose: Define feedback states: neutral → processing → success/error.

Follow Through & Overlapping: Icon animates, then label appears. Stagger confirmation elements.

Slow In/Slow Out: Success: ease-out (confident arrival). Error: ease-in-out (shake settles).

Arcs: Checkmarks draw in arcs, not straight lines. Error X's cross naturally.

Secondary Action: Checkmark draws + color shifts + scale bounces for rich feedback.

Timing:

Exaggeration: Success deserves celebration. Overshoot scale to 1.2, bold colors, confident motion.

Solid Drawing: Feedback icons must be clear at a glance. Recognition in 100ms or less.

Appeal: Positive feedback should feel rewarding. Negative feedback firm but not punishing.

Timing Recommendations

Feedback Type Duration Auto-dismiss Easing

Inline Validation 150ms No ease-out

Checkmark Draw 400ms 3000ms ease-out

Success Toast 300ms 4000ms ease-out

Error Shake 400ms No ease-in-out

Error Toast 300ms 6000ms ease-out

Save Indicator 200ms 2000ms ease-out

Implementation Patterns

/* Checkmark draw */ .checkmark { stroke-dasharray: 50; stroke-dashoffset: 50; animation: draw-check 400ms ease-out forwards; }

@keyframes draw-check { to { stroke-dashoffset: 0; } }

/* Success with scale */ .success-icon { animation: success 500ms cubic-bezier(0.34, 1.56, 0.64, 1) forwards; }

@keyframes success { 0% { transform: scale(0); opacity: 0; } 60% { transform: scale(1.2); opacity: 1; } 100% { transform: scale(1); opacity: 1; } }

/* Error shake */ .error-shake { animation: shake 400ms ease-in-out; }

@keyframes shake { 0%, 100% { transform: translateX(0); } 20%, 60% { transform: translateX(-6px); } 40%, 80% { transform: translateX(6px); } }

/* Inline validation */ .field-valid { animation: valid-pop 200ms ease-out; }

@keyframes valid-pop { 0% { transform: scale(0.8); opacity: 0; } 100% { transform: scale(1); opacity: 1; } }

SVG Checkmark Pattern

Auto-Dismiss Pattern

// Show success, auto-hide element.classList.add('success-visible');

setTimeout(() => { element.classList.remove('success-visible'); element.classList.add('success-hidden'); }, 3000);
