CSS Animation Knowledge

CSS3 animations are defined by @keyframes rules and controlled by the animation property. Compared to JavaScript animations, CSS animations are optimized by the browser rendering engine for better performance and are easier to maintain with declarative syntax. Prefer transform and opacity for animations as these properties can be GPU-accelerated without triggering reflow or repaint.

What is CSS animation?

CSS animation creates web page animations using CSS3 animation properties and @keyframes rules. Smooth transitions, rotations, scaling, and movement can be achieved without JavaScript, with excellent performance and easy maintenance.

What is the difference between CSS animation and CSS transition?

CSS transitions only switch between two states and need a trigger (like hover). CSS animations can define multiple keyframes with auto-play, loop, and pause controls — much more powerful.

How to choose an easing function?

ease (default, slow-fast-slow), linear (constant speed), ease-in (slow start), ease-out (slow end), ease-in-out (slow both ends). Use cubic-bezier for custom curves. ease-out for natural motion, linear for mechanical.

How to make an animation loop infinitely?

Set animation-iteration-count to infinite. In this tool, select 'Infinite' from the iteration dropdown. Note: infinite animations may affect performance — use only when needed.

How to optimize CSS animation performance?

Prefer transform and opacity for animations (GPU-accelerated). Avoid animating width/height/margin which trigger reflow. Use will-change for browser pre-optimization. Minimize simultaneous animations.

How to use the generated code?

Copy the generated CSS to your stylesheet and add the animation class to your HTML element. Place @keyframes at the top of your stylesheet and the animation property in the corresponding selector.
