CSS Animation Generator with Presets and a Visual Editor
The CSS Animation Generator lets you build @keyframes animations visually, without writing them by hand. Pick a ready-made preset, tweak the timing and easing, and copy clean, production-ready CSS straight into your stylesheet.
It is made for frontend developers and UI designers who want polished motion fast: prototype an entrance effect, experiment with easing curves, or fine-tune a looping spinner. You can choose from 35 presets across four categories, adjust every animation property, and open the Keyframe Editor to shape each step yourself. A live preview replays your animation as you work.
How to Create a CSS Animation
Choose a preset
Pick a category tab — Entrance, Exit, Emphasis, or Loop — then click any preset to apply it. The preview plays instantly and every property and keyframe updates to match.
Adjust the properties
Fine-tune Duration (0.1s to 5s), Delay (0s to 5s), Easing, Iteration (1, 2, 3, or infinite), Direction (normal, reverse, alternate), and Fill Mode (none, forwards, backwards, both).
Edit keyframes (optional)
Open the Keyframe Editor to shape individual steps. Set opacity, translateX, translateY, rotate, and scale at each percentage, and click Add Keyframe to insert a new step with interpolated values.
Preview and copy
Use play, pause, and restart to review the motion, and switch the preview shape (box, circle, text) and background color to test it in context. When it looks right, click Copy to grab the full CSS.
Features
35 Animation Presets
A library of 35 presets across four categories: Entrance, Exit, Emphasis, and Loop, each with sensible default timing.
Full Property Control
Set duration, delay, easing, iteration count, direction, and fill mode from one panel of visual controls.
9 Easing Options
Use the standard curves plus custom bounce, elastic, smooth, and stepped easing for frame-by-frame effects.
Visual Keyframe Editor
A timeline shows every keyframe; click any step to edit opacity, translateX/Y, rotate, and scale, then add or remove steps.
Smart Interpolation
New keyframes are auto-filled from surrounding steps, so inserted frames stay smooth instead of jumping.
Live Preview
Watch the animation replay in real time with play, pause, and restart controls as you change any setting.
Shape and Background Options
Preview on a box, circle, or text element and set a custom background color to test motion in different contexts.
Clean Code Output
Get the complete @keyframes block plus the animation shorthand, updated live, with one-click copy to your clipboard.
Dark Mode
A built-in dark theme keeps the editor comfortable to use in low-light setups.
Runs in Your Browser
All processing is client-side, so your animations stay on your device with nothing sent to a server.
Frequently Asked Questions
How do I create a CSS animation?
Pick a preset from a category, adjust the duration, easing, and other properties, then optionally open the Keyframe Editor to refine each step. When the live preview looks right, click Copy to get the full CSS. There is nothing to install or sign up for.
What are CSS keyframes and @keyframes?
A @keyframes rule defines the named stages of an animation, with each keyframe set at a percentage from 0% to 100%. The browser interpolates between those stages over the animation's duration. This generator builds the @keyframes rule for you and applies it through the animation shorthand.
What CSS properties can I animate?
The Keyframe Editor controls opacity, translateX, translateY, rotate, and scale — properties that are GPU-accelerated in most browsers for smooth motion. Some presets also use richer transforms such as scaleX, scaleY, skewX, skewY, and rotateX, which carry through to the generated code.
What does fill mode do?
Fill mode controls how the element looks before and after the animation. none returns it to its original styles, forwards keeps the last keyframe's styles, backwards applies the first keyframe during the delay, and both combines the two. For entrance animations, forwards usually keeps the element visible after it fades in.
Which easing function should I use?
Use ease-out for entrances (fast start, gentle stop), ease-in for exits (gentle start, fast finish), and ease-in-out for emphasis and loops. Pick linear for continuous spinners, and reach for bounce or elastic when you want a playful, attention-grabbing feel.
How do I make a looping (infinite) animation?
Set Iteration to infinite. The Loop presets — like Spin, Float, and Wave — already use infinite iterations, so they keep playing on their own. Pairing infinite with the alternate direction creates a smooth back-and-forth motion.
What is the difference between a CSS animation and a transition?
A transition animates a single change between two states and needs a trigger such as a hover or class change. A keyframe animation can define many intermediate stages, can loop, and starts on its own. This tool focuses on @keyframes animations, which give you finer control over multi-step motion.
How do I copy the generated CSS?
Click the Copy button on the code panel. It copies the full output — the @keyframes block plus a .element rule with the animation shorthand — to your clipboard, ready to paste into your stylesheet. The output uses standard properties supported in all modern browsers, with no vendor prefixes needed.
