CSS Animations and Keyframes

CSS animations enable rich motion without JavaScript. Here's how to create them.

Best Practices#

Performance:
✓ Animate transform and opacity
✓ Use will-change sparingly
✓ Avoid animating layout properties
✓ Test on lower-end devices

Accessibility:
✓ Respect prefers-reduced-motion
✓ Provide pause controls for loops
✓ Don't rely on animation for info
✓ Keep durations reasonable

Design:
✓ Use easing for natural motion
✓ Keep animations purposeful
✓ Maintain consistency
✓ Don't overuse animations

Code:
✓ Use CSS custom properties
✓ Create reusable keyframes
✓ Document animation intent
✓ Clean up will-change

CSS animations create engaging user experiences. Use keyframes for complex multi-step animations, prioritize performance with transform and opacity, and always respect accessibility preferences. Start with purpose, keep animations subtle, and test across devices.
