CSS Animation Keyframes Builder
Create simple CSS keyframes and preview the animation in your browser.
Build CSS keyframes visually
Writing @keyframes by hand means juggling percentages and properties in your head. This builder lets you define animation steps and previews the result live, so you can see the motion instead of imagining it from a block of CSS.
Watching the animation play as you tweak the steps makes it far easier to get timing and easing right. When it looks the way you want, copy the @keyframes rule and the animation shorthand into your stylesheet.
Copy-ready CSS
The CSS is generated live in your browser as you adjust the controls, so there is nothing to install and nothing is uploaded. Copy the ready-to-use declaration straight into your stylesheet, tweak the values to taste, and it will render exactly as it does in the preview here.
