CSS Animation Generator
LiveBuild CSS @keyframes animations visually with a live preview and copy-ready CSS output.
Understanding Cascading Style Sheets
CSS animations using @keyframes let you create smooth, performant motion effects without JavaScript. However, the syntax for keyframe definitions, timing functions, and animation shorthand properties is verbose and easy to get wrong. A visual builder lets you see the animation playing in real time as you configure it, making it far faster to get the desired motion compared to writing CSS manually and refreshing the browser.
Create CSS @keyframes animations using a visual editor. Set animation name, duration, timing function (ease, linear, cubic-bezier), iteration count, direction, and fill mode. Add keyframe stops at 0%, 50%, and 100% with CSS properties. See a live preview of the animation and copy the complete CSS code including both the @keyframes block and animation shorthand property.
The Devkitr CSS Animation Generator provides a visual editor for @keyframes animations. Set timing, easing, iteration, and keyframe property values, then copy the complete CSS block ready to paste into your stylesheet.
In a typical development workflow, CSS Animation Generator becomes valuable whenever you need to build css @keyframes animations visually with a live preview and copy-ready css output. Whether you are working on a personal side project, maintaining production applications for a company, or collaborating with a distributed team across time zones, having a reliable browser-based generation tool eliminates the need to install desktop software, write one-off scripts, or send data to third-party services that may log or retain your information. Since CSS Animation Generator processes everything locally on your device, your data stays private and your workflow stays uninterrupted — open a browser tab, paste your input, get your result.
Key Features
Keyframe Editor
Define CSS properties at 0%, 50%, and 100% keyframe stops. Add transform, opacity, color, and any other animatable CSS property.
Timing Controls
Configure duration (ms), delay (ms), timing function (ease, linear, ease-in, ease-out, ease-in-out, cubic-bezier), iteration count, direction, and fill mode.
Live Preview
See the animation running in real time on a preview element as you adjust settings. Pause and replay at any time.
Complete CSS Output
Generates both the @keyframes block and the animation shorthand property. Copy and paste directly into your stylesheet.
How to Use CSS Animation Generator
Set Animation Properties
Configure name, duration, timing function, delay, iteration count (finite or infinite), direction, and fill mode.
Define Keyframes
Enter CSS property values at 0%, 50%, and 100% stops. Example: opacity: 0 at 0%, opacity: 1 at 100% for a fade-in.
Preview
Watch the live preview element animate with your settings. Adjust until the motion feels right.
Copy CSS
Copy the generated @keyframes block and animation property and paste into your CSS file.
Use Cases
Entrance Animations
Create fade-in, slide-up, or scale-in animations for page elements using opacity and transform keyframes.
Loading Spinners
Build a rotating loader using transform: rotate(360deg) at 100% with animation-iteration-count: infinite and linear timing.
Hover Effects
Define pulse or bounce animations triggered by CSS :hover that play once or loop while hovered.
Attention-Seeking Effects
Create shake, wiggle, or flash animations using rapid keyframe changes for notification badges and call-to-action elements.
Pro Tips
Use transform instead of top/left/width/height for smooth animations — transform and opacity are GPU-accelerated and do not trigger layout reflow.
Add will-change: transform or will-change: opacity to the animated element to hint to the browser to create a compositor layer before the animation starts.
Avoid animating box-shadow, border-radius, or gradient properties — they trigger paint operations and are not GPU-accelerated.
Common Pitfalls
Using animation-fill-mode: none and seeing the element snap back to its original state
Fix: Set animation-fill-mode: forwards to keep the element in the last keyframe state after the animation ends, or both to apply the initial keyframe before the delay period.
