Accessibility Issues
Make animations inclusive using Disney's principles thoughtfully.
Problem Indicators
- •Motion sickness complaints
- •Vestibular disorder triggers
- •Screen reader confusion
- •Cognitive overload
- •Seizure risk (flashing)
- •Keyboard focus lost during animation
Diagnosis by Principle
Squash and Stretch
Issue: Excessive distortion causes disorientation
Fix: Reduce or eliminate squash/stretch for users with prefers-reduced-motion. Use opacity changes instead.
Secondary Action
Issue: Too many moving elements Fix: Limit to one animated element at a time. Secondary actions should be subtle or removed.
Exaggeration
Issue: Dramatic motion triggers vestibular responses Fix: Reduce scale, rotation, and position changes. Keep movements small and predictable.
Timing
Issue: Animations too fast or too slow Fix: Provide consistent, predictable timing. Avoid sudden speed changes.
Arcs
Issue: Curved motion paths cause tracking difficulty Fix: Use linear motion for essential UI. Save arcs for optional decorative elements.
Quick Fixes
- •Respect
prefers-reduced-motion- Always check and honor - •No autoplay animation - Let users trigger motion
- •Keep focus visible - Never animate focus indicator away
- •Announce changes - Use ARIA live regions for dynamic content
- •Provide pause controls - For any looping animation
Troubleshooting Checklist
- • Does animation respect
prefers-reduced-motion? - • Is there a way to pause/stop animations?
- • Are state changes announced to screen readers?
- • Does keyboard focus remain visible and logical?
- • Is flash rate under 3 per second?
- • Can users complete tasks without animation?
- • Are animations triggered by user action (not autoplay)?
- • Test with screen reader enabled
Code Pattern
@media (prefers-reduced-motion: reduce) {
*,
*::before,
*::after {
animation-duration: 0.01ms !important;
animation-iteration-count: 1 !important;
transition-duration: 0.01ms !important;
}
}
// Check preference in JS const prefersReducedMotion = window.matchMedia( '(prefers-reduced-motion: reduce)' ).matches;
