A CSS animation generator lets you build keyframe animations visually without writing code manually. Define property values at each keyframe step, set timing, duration, and iteration — then copy production-ready @keyframes CSS with the animation shorthand. Perfect for fade-ins, bounces, slides, and custom effects.

How to Use the CSS Animation Generator
CSS @keyframes animations give designers full control over how elements move, fade, and transform over time — without JavaScript. This free CSS animation generator provides a visual keyframe editor, live preview, and one-click export so you can build complex animations in seconds.
Step 1: Choose a Preset or Start Fresh
Click any preset button to instantly load a classic animation: fade-in, slide-in, bounce, rotate, pulse, or shake. Presets configure all keyframe values and settings. You can then customize any keyframe or setting after loading a preset.
Step 2: Set Animation Timing
Adjust the duration slider (0.1s to 10s) and timing function. The timing function controls the acceleration curve: ease starts slow and ends slow, linear is constant speed, ease-in accelerates, ease-out decelerates. The "spring" option uses a cubic-bezier overshoot for a bouncy feel.
Step 3: Edit Keyframes
Each keyframe row lets you set transform properties (translateX, translateY, scale, rotate) and opacity at that time step. The generator interpolates smoothly between keyframes. Adding more steps gives you finer control over the animation curve.
Step 4: Configure Iterations and Direction
Set iteration count to a number for finite loops or "infinite" for continuous animation. The alternate direction reverses on every other iteration — great for ping-pong effects. Fill mode "forwards" keeps the final state after the animation ends.
Step 5: Copy Your CSS
The output includes the complete @keyframes rule plus the animation shorthand property ready to apply to your element. Click Copy CSS and paste directly into your stylesheet.
FAQ
Is this CSS animation generator free?
Yes, completely free with no limits or account required. All animation rendering and CSS generation happen locally in your browser.
What is the difference between CSS animations and transitions?
CSS transitions animate between two states (start and end). CSS animations use @keyframes to define multiple intermediate states, allowing looping, direction reversal, and complex multi-step effects that don't require user interaction to trigger.
How do keyframe percentages work?
Keyframe percentages represent points in the animation timeline. 0% is the start, 100% is the end. You can define any number of intermediate states (25%, 50%, 75%, etc.). CSS smoothly interpolates between defined keyframes.
What is the animation-fill-mode property?
animation-fill-mode controls what styles apply before and after the animation. 'forwards' keeps the end state after the animation ends. 'backwards' applies the start state before the animation begins. 'both' combines both behaviors.
What timing functions are available for CSS animations?
Standard options are ease, linear, ease-in, ease-out, ease-in-out, and step functions. You can also use cubic-bezier(x1,y1,x2,y2) for custom easing curves. Each keyframe can have its own timing function via animation-timing-function inside the keyframe rule.
Can I animate multiple properties at once?
Yes, CSS animations can animate multiple properties simultaneously within the same @keyframes rule. Each keyframe simply lists all the properties you want at that time step, and the browser interpolates all of them in parallel.
How do I loop a CSS animation infinitely?
Set animation-iteration-count to 'infinite'. The element will animate continuously until the animation is paused via JavaScript or the element is removed from the DOM.
