What is CSS Animation Generator?

CSS Animation Generator is a free visual tool for building CSS @keyframes animations without writing code by hand. CSS animations consist of two parts: a @keyframes rule that defines the animation states and an animation shorthand property that controls timing, duration, and behavior. Creating complex multi-step animations manually is tedious and error-prone. This tool provides a visual editor with a live preview so you can see your animation in real time as you adjust parameters like duration, timing function, delay, iteration count, direction, and fill mode.

How to Use This Tool

Start by choosing a preset animation like Fade In, Bounce, Shake, or Rotate, or build one from scratch. Adjust the animation settings including name, duration, timing function (ease, linear, cubic-bezier), delay, iteration count, direction, and fill mode. Edit individual keyframes by setting percentage, transform values, and opacity. Add up to 10 keyframes for complex multi-step animations. Watch the live preview update as you make changes, then copy the generated CSS code directly into your project.

Common Use Cases

Creating entrance animations for hero sections, modals, and page transitions
Building loading spinners and skeleton screen animations for better user experience
Designing attention-grabbing hover effects and notification pulses
Prototyping animation ideas visually before implementing them in production code

Why Use a Client-Side Tool?

All animation generation and previewing happens entirely in your browser. No data is sent to any server, there is no account required, and the tool works offline after the page loads. The generated CSS is standard, framework-agnostic code that works in any modern browser. You can use it with React, Vue, Angular, vanilla HTML, or any other frontend stack.

Frequently Asked Questions

Can I animate properties other than transform and opacity?

The visual editor focuses on transform and opacity since these are the most performant CSS properties to animate. They are composited on the GPU and do not trigger layout recalculations. For other properties, you can use the generated code as a starting point and add additional properties manually in your stylesheet.

What is the difference between animation fill modes?

"forwards" keeps the final keyframe state after the animation ends. "backwards" applies the first keyframe state during the delay period. "both" combines forwards and backwards behavior. "none" means the element reverts to its original state when the animation completes.

Do CSS animations work in all browsers?

CSS animations are supported in all modern browsers including Chrome, Firefox, Safari, and Edge. No vendor prefixes are needed for current browser versions. The generated code uses standard CSS syntax that works across all major platforms.
