CSS Animation Generator
Build a CSS @keyframes animation visually and get the full animation declaration, ready to preview and copy.
Define start/end (or multi-step) keyframe states and animation timing - watch it play live, then copy the @keyframes and animation CSS.
For a one-time transform without animation, see the CSS Transform Generator instead.
What Does @keyframes Do?
A @keyframes rule defines a sequence of styles an element passes through over time, and the animation property (referencing that keyframes name) controls duration, timing, and repetition on the element.
Why Use This Tool?
Coordinating keyframe percentages with duration and easing to get a natural-feeling animation usually takes several preview cycles - this tool plays the animation live as you adjust values.
How to Use It
- Define keyframe states (e.g. opacity/transform at 0% and 100%, or add more steps).
- Set duration, timing function, and iteration count.
- Preview the animation playing live.
- Copy the generated @keyframes rule and animation declaration.
Limitations
This generates standard CSS keyframe animations - JavaScript-driven or scroll-triggered animations are a different technique not covered by this pure-CSS tool.
