About this tool
Visual editor for keyframes, duration, easing, delay, and iteration. Preview motion in real time and copy a complete @keyframes rule and animation shorthand.
Combine with the CSS Transition Builder for hover states, the Cubic Bezier Generator for custom easing, and the Keyframes Generator for multi-step animations.
Preview runs entirely in the browser.
How to use
- Pick a preset or configure duration, timing, iteration, and key properties.
- Preview the animation live in the workspace.
- Copy the generated @keyframes plus animation shorthand CSS.
- Paste into your stylesheet and tweak selectors to match your components.
Example
Fade-in animation export
Input
name: fadeIn, duration: 300ms, easing: ease-out
Output
@keyframes fadeIn {
from { opacity: 0; }
to { opacity: 1; }
}
.element {
animation: fadeIn 300ms ease-out;
}Limitations
- Preview approximates browser behavior — GPU/compositor differences can remain.
- Does not export Web Animations API JavaScript equivalents.
- Complex multi-element choreography still needs hand-written timelines.
