CSS Animation Generator
Build CSS @keyframes animations with a visual editor and live preview. Start from a preset, tweak duration, easing, delay, and iteration count, then copy ready-to-paste CSS. All in your browser.
What you'll use this for

Drop a fade-up or pop-in animation onto hero text without learning the syntax.
Notification badges
Build pulse and bounce animations for alerts and unread indicators.

How to build a CSS animation
Pick a preset
Fade, slide, pop, shake, bounce, spin — each is a real-world starting point.
Tweak the timing
Duration, delay, iteration count, easing curve. The preview updates live.
Copy the CSS
You get a clean block with the @keyframes definition and the animation shorthand, ready to paste.
Frequently asked questions
No. The output is plain CSS that runs in every modern browser. No JavaScript, no preprocessor.
This tool offers preset keyframes and full control over timing. For per-keyframe editing, paste the output into your editor and tweak.
Wrap the animation in @media (prefers-reduced-motion: no-preference) when shipping to production, so users who request less motion aren’t affected.
Yes. All presets use vanilla CSS animation properties supported since iOS 8 / macOS Yosemite.
Yes — the preview applies the exact same CSS you copy.
About CSS animations
CSS animations let you describe a change over time using @keyframes and apply it with the animation shorthand. They’re GPU-accelerated for common properties (transform, opacity) and don’t require JavaScript.
The pattern
@keyframes name { 0%{...} 100%{...} }
.box { animation: name 1s ease-in-out 0s infinite normal forwards; }What you can animate
- Cheap (GPU) —
transformandopacity. Use these for smooth 60 fps animations. - Expensive (layout/paint) —
width,height,top,left. Avoid for high-FPS work.
Accessibility
Respect prefers-reduced-motion. Some people experience nausea or vestibular distress from animation; a media query can turn animations off for them.
