About the CSS Animation Generator

The CSS Animation Generator builds complete keyframe animations from ready-made presets — fade, slide, bounce, spin and pulse. Pick a preset, then tune duration, timing-function, iteration count and direction while a live element animates so you can see the result immediately.

It saves you from hand-writing @keyframes blocks and remembering the animation shorthand order. The output includes both the @keyframes rule and the animation property, ready to paste into any stylesheet.

All generation happens locally in your browser — free, private, and works offline once loaded.

Frequently asked questions

What is the difference between transition and animation in CSS?

A transition animates between two states and needs a trigger like :hover. An animation uses @keyframes to define many steps and can run automatically, loop, and play without any interaction. Animations are more powerful; transitions are simpler.

How do @keyframes work?

A @keyframes rule names an animation and lists style snapshots at percentages (0% to 100%, or from/to). The browser interpolates between those snapshots over the animation's duration to produce smooth motion.

How do I make an animation loop forever?

Set animation-iteration-count to infinite. This tool exposes an infinite option, and the copied CSS includes it in the animation shorthand so the effect repeats endlessly.

What does animation-direction do?

It controls playback order: normal plays forward, reverse plays backward, alternate plays forward then backward each cycle, and alternate-reverse does the opposite. alternate is popular for smooth back-and-forth pulses.

Are CSS animations better than JavaScript animations?

For simple, declarative motion CSS animations are lighter and run on the compositor thread, staying smooth even when the main thread is busy. JavaScript is better when you need dynamic values, physics or fine playback control.
