Best Practices
Properties:
✓ Use transform and opacity
✓ Specify properties explicitly
✓ Avoid "all" in production
✓ Use appropriate durations
Timing:
✓ 200-300ms for UI feedback
✓ 300-500ms for emphasis
✓ ease-out for entering
✓ ease-in for exiting
Accessibility:
✓ Respect prefers-reduced-motion
✓ Keep focus states visible
✓ Don't hide content permanently
✓ Test with keyboard
Avoid:
✗ Transitioning layout properties
✗ Too long durations
✗ Transitions on page load
✗ Motion that causes discomfort
Conclusion
CSS transitions provide smooth, performant animations for state changes. Focus on transform and opacity for best performance, use appropriate timing functions for natural movement, and respect user preferences for reduced motion. Keep durations short for UI responsiveness and use JavaScript to coordinate complex transition sequences.
