Frequently Asked Questions
What is CSS animation?
CSS animations allow you to gradually change element styles over time using keyframes. They're hardware-accelerated, performant, and don't require JavaScript. Animations can control multiple properties and provide precise timing control.
What's the difference between animation timing functions?
Timing functions control acceleration: 'ease' starts slow, speeds up, then slows down; 'linear' maintains constant speed; 'ease-in' starts slow; 'ease-out' ends slow; 'ease-in-out' combines both. Cubic-bezier allows custom curves for unique effects.
When should I use animation-fill-mode?
'forwards' keeps the final keyframe styles after animation ends; 'backwards' applies first keyframe styles during delay; 'both' combines both. Use 'forwards' for permanent state changes, like fade-in effects that should stay visible.
What does animation-direction do?
'normal' plays forward; 'reverse' plays backward; 'alternate' alternates direction each iteration; 'alternate-reverse' starts backward. Use 'alternate' for ping-pong effects like pulsing or oscillating animations.
Are CSS animations performant?
Yes! CSS animations are hardware-accelerated when using transform and opacity properties. They perform better than JavaScript animations and work smoothly even on mobile devices. Avoid animating expensive properties like width, height, or top/left.
