CSS Animation Generator — Free Online Tool

What Is CSS Animation Generator?

A free online CSS animation generator. Choose from 10 ready-made keyframe animations — bounce, shake, pulse, spin, fade in, slide in, flip, wobble, and swing. Adjust duration, easing, delay, iteration count, and direction. Preview and copy the generated code.

CSS animations bring web interfaces to life with movement, visual feedback, and engaging transitions. From subtle hover effects to attention-grabbing loading indicators, keyframe animations are essential for modern web design. CSS Animation Generator provides 10 ready-made keyframe animations with customizable timing, easing, and repetition settings.

Choose from bounce, shake, pulse, spin, fade in, slide in left, slide in right, flip, wobble, and swing. Each animation has a dedicated @keyframes definition that handles the start, intermediate, and end states. Select an animation and preview it immediately on the demo element.

Adjust the duration (how long one cycle takes, from 0.1s to 10s), easing function (ease, ease-in, ease-out, ease-in-out, linear, or a custom cubic-bezier value), delay (time before the animation starts, from 0s to 5s), iteration count (1, 2, 3, infinite, or custom), and direction (normal, reverse, alternate, alternate-reverse).

The live preview shows the animation playing on a demo element, with the current @keyframes code displayed alongside the full CSS. Copy the complete animation code — including both the @keyframes rule and the animation property — with one click. The generated code uses vendor-prefix-free syntax, which works in all modern browsers.

Real-World Use Cases for CSS Animation Generator

Adding a Subtle Pulse Animation to a Call-to-Action Button

A CTA button needs gentle pulsing to draw attention. Select the pulse animation, set duration to 2s, easing to ease-in-out, and iteration to infinite. The button gently scales up and down, creating subtle visual emphasis without being distracting.

Creating a Loading Spinner with Bounce Animation

A loading state needs an engaging indicator. Select the bounce animation, set duration to 1s, easing to ease-in-out, and iteration to infinite. The demo element bounces continuously. Adapt the keyframe to rotate 360 degrees for a spinner variation.

Animating a Fade-In Entrance for Page Content

Page sections should fade in as they appear. Select the fade-in animation, set duration to 1.5s, easing to ease-out, delay to 0.3s, iteration to 1. The element fades from transparent to opaque with a slight upward movement. Apply this animation class to page sections using your preferred intersection observer library.

Pro Tips for CSS Animation Generator

1Use the cubic-bezier easing option for precise timing control. Common values: ease (0.25, 0.1, 0.25, 1), ease-in (0.42, 0, 1, 1), ease-out (0, 0, 0.58, 1).
2For entrance animations (fade in, slide in), use a duration of 0.5-1.5s and ease-out easing for natural deceleration. For emphasis animations (bounce, pulse), 1-3s with ease-in-out works well.
3Avoid animating too many elements simultaneously. Performance is best when animating transform and opacity properties. Avoid animating width, height, or position properties that trigger layout recalculations.
4Set animation-fill-mode: forwards to keep the end state visible after the animation completes. This is essential for entrance animations where the element should stay visible.
