CSS Animation Generator

What is CSS Animation Generator?

CSS Animation Generator builds CSS @keyframes animations through a visual timeline editor with live preview. It supports multiple keyframe stops with individual property controls for transform (translate, rotate, scale), opacity, color, and other animatable CSS properties. The tool generates the complete CSS including animation shorthand, timing function (easing), delay, iteration count, direction, and fill mode.

Frontend developers adding micro-interactions, UI designers prototyping motion design, and web developers creating engaging page animations. The tool runs entirely in your browser — your data never leaves your device.

How to Use CSS Animation Generator

1. Add keyframe stops on the timeline — 0% for the start state and 100% for the end state
2. Set CSS properties at each keyframe — transform, opacity, color, or any animatable property
3. Configure timing function (ease, ease-in-out, cubic-bezier), duration, and delay
4. Preview the animation in real time with play, pause, and speed controls
5. Copy the generated @keyframes rule and animation property CSS

Common Use Cases

• Creating entrance animations like fade-in, slide-up, and scale-in for page elements
• Building loading spinner and skeleton screen pulse animations
• Designing hover state animations for buttons, cards, and interactive elements
• Creating attention-getting animations for notification badges and alert indicators
• Prototyping scroll-triggered animations before implementing them with Intersection Observer

Pro Tips

• Animate only transform and opacity for smooth 60fps performance — these properties are GPU-composited and do not trigger layout recalculation (reflow) or repaint
• Use cubic-bezier easing for natural-feeling motion — linear animations look mechanical while cubic-bezier(0.4, 0, 0.2, 1) (Material Design standard) feels fluid
• Set animation-fill-mode: forwards to keep the element in its final keyframe state after the animation completes — without it, the element snaps back to its original state
