How to Use

Building a CSS animation is visual and instant. Follow these steps to create your motion:

Design Process

  1. Select a Preset: Use the quick buttons (Fade, Bounce, Pulse) to load a starting template.
  2. Configure Timing: Set your Duration and Easing to control the speed and feel of the motion.
  3. Add Keyframes: Click Add Step to insert more waypoints into your animation sequence.
  4. Live Preview: Watch the sandbox element (Box, Circle, or Text) react to your changes in real-time.
  5. Export Code: Copy the generated CSS block and paste it into your project's stylesheet.

Our tool is designed to encourage best practices, focusing on GPU-accelerated properties like transform and opacity to keep your user interfaces buttery smooth at 60FPS.

FAQ

What is a CSS keyframe?
Keyframes are the foundation of CSS animations. They allow you to define the state of an element at specific points during an animation sequence (e.g., 0%, 50%, 100%). The browser then interpolates the values between these points.
How do I use the generated code?
The generator provides two parts: the @keyframes definition and an animation class. Copy both into your CSS file, then apply the generated class (e.g., .animate-custom-animation) to any HTML element you want to animate.
What does 'iteration count' mean?
The iteration count determines how many times the animation sequence will repeat. 'Infinite' means the animation will loop forever until the element is removed or the property is changed.
Are CSS animations better than JavaScript animations?
For simple UI transitions and loops, CSS animations are generally superior because they can be offloaded to the GPU, leading to smoother performance and higher frame rates, especially on mobile devices.
