Our free CSS animation generator lets you build professional keyframe animations visually without writing complex code from scratch. Configure every aspect of your animation -- from duration and timing functions to individual keyframe properties -- and see the results instantly with a live preview that updates in real time.
To build a subtle fade-in effect, an eye-catching bounce, or a custom multi-step animation, this tool provides 10 built-in presets and a full keyframe editor. Each preset is fully customizable, so you can use them as starting points and fine-tune every property including transform, opacity, and background color at any percentage point.
The generator outputs clean, production-ready CSS code with proper @keyframes syntax and individual animation properties. Simply copy the generated code and paste it into your stylesheet. Your animations are never uploaded or stored.

How to Use the CSS Animation Generator
- Choose a starting point: Select one of the 10 built-in presets like Bounce, Fade In, or Spin, or start with a blank animation.
- Adjust animation properties: Set the duration, timing function, iteration count, direction, fill mode, and delay using the intuitive controls.
- Edit keyframes: Add, remove, or modify keyframes at any percentage point. Set transform values, opacity, and background colors for each keyframe.
- Preview your animation: Watch the live preview update in real time. Click Replay to restart the animation and verify the result.
- Copy the CSS code: Click the Copy CSS button to copy the generated @keyframes and animation property code to your clipboard.
- Paste into your project: Add the copied CSS to your stylesheet and apply the animation class to your HTML elements.

Frequently Asked Questions
What browsers support CSS animations?
CSS animations are supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. The generated code uses standard @keyframes syntax that works across all current browser versions.
Can I combine multiple animations on one element?
Yes, you can apply multiple animations to a single element by separating animation names with commas in CSS. Generate each animation separately and combine them in your stylesheet.
What is a cubic-bezier timing function?
A cubic-bezier function defines a custom acceleration curve for your animation. It uses four values to control how the animation speeds up and slows down, giving you precise control beyond standard options like ease-in or ease-out.
Tips & Best Practices
- Use transform and opacity: Animate transform and opacity properties for the best performance, as they can be hardware-accelerated by the GPU.
- Keep animations subtle: Subtle animations (0.2s-0.5s) feel more polished than long, dramatic ones for most UI interactions.
- Respect user preferences: Use the prefers-reduced-motion media query to disable or reduce animations for users who prefer less motion.
- Choose appropriate fill modes: Use "forwards" to keep the final state, "backwards" to apply the first keyframe during delay, or "both" for complete control.
- Test across devices: Preview your animations on mobile devices where performance may differ from desktop browsers.
