What does this tool do?
The CSS Animation Generator lets you build keyframe-based animations visually using ready-made presets. Pick effects like fadeIn, slideUp, bounceIn, shake, pulse, or rotate, tune the duration, delay, timing curve, iteration count, direction, and fill-mode, and watch a live preview. The generated @keyframes and animation shorthand can be copied with one click.
How to use it
- Adjust the values and options.
- See the result in the live preview.
- Copy the generated CSS/code into your project.
Presets and live preview
The tool ships nine ready-made animations: fadeIn and slideUp for entrances, bounceIn and wobble for attention-grabbing motion, shake and flash for error feedback, and pulse, rotate, and slideLeft for accents. Clicking a preset plays the animation in real time on the central box, so you see the result before adding any code to your page. The preview restarts automatically each time you change a setting.
Tuning the timing parameters
Alongside duration (0.1-10s) and delay, you can set the timing function to ease, linear, ease-in-out, or cubic-bezier(0.68,-0.55,0.27,1.55) for an overshoot bounce. Set iteration to 'infinite' for continuously spinning loaders, or direction to 'alternate' for back-and-forth motion. The fill-mode 'forwards' keeps the final frame after the animation ends, preventing the element from snapping back to its starting state.
Frequently asked questions
Can I edit the keyframes myself?
The tool lets you choose among nine presets and generates their @keyframes rules. After copying the output, you're free to edit the keyframe percentages and transform values by hand in your own CSS file.
How do I make the animation loop forever?
Choose 'infinite' from the Iteration menu. Combined with a preset like rotate or pulse, this produces a seamless continuous loop ideal for loading spinners and heartbeat effects.
