What is a CSS Animation?

CSS animations allow elements to transition between styles over a defined period using @keyframes rules. Unlike CSS transitions (which only move between two states), animations support multiple keyframes and loop indefinitely — making them ideal for loading spinners, attention effects, and decorative motion.

How to Use This Generator

Choose a preset to start quickly, or configure every property manually. Add keyframes at any percentage point and define the transform (translate, rotate, scale), opacity, and background-color at each step. The live preview updates instantly, and the “Replay” button restarts the animation so you can evaluate it from the beginning.

Key Animation Properties

  • animation-duration — how long one cycle takes (in seconds).
  • animation-timing-function — easing curve (ease, linear, ease-in-out, etc.).
  • animation-delay — how long to wait before the animation starts.
  • animation-iteration-count — number of cycles, or infinite.
  • animation-direction — whether the animation runs forward, backward, or alternates.
  • animation-fill-mode — what styles are applied before/after the animation runs.

Browser Support

CSS animations with @keyframes are supported in all modern browsers (Chrome, Firefox, Safari, Edge) without vendor prefixes. They are hardware-accelerated when using transform and opacity, which is why these two properties are recommended for smooth 60 fps animations.
