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.

Frequently Asked Questions

transform and opacity are the most efficient because browsers can animate them without recalculating the layout. Avoid animating width, height or top/left where possible.

A transition animates between two states when something changes, such as on hover. An @keyframes animation can have many steps, loop and start on its own.

Wrap animations in @media (prefers-reduced-motion: no-preference), or reduce them inside @media (prefers-reduced-motion: reduce).
