Free CSS Animation Playground

Learn CSS animations with a real-time playground.

A CSS animation playground is an interactive workspace where you change properties like keyframes, duration, timing functions, transforms, and transitions and see the result instantly. This free CSS animation generator helps you learn CSS animations with live examples instead of trial-and-error inside a full project.

Built by Zap Code for kids who want to turn small experiments into full apps and games.

Playground Highlights

11 preset animations

Bounce, spin, slide, pulse, shake, flip, swing, wobble, and more.

Custom @keyframes editor

Paste your own animation rule and preview it instantly.

Copy-ready CSS output

Keep the generated CSS beside the preview while you learn.

Animation Playground

Pick a preset, tune the easing, toggle the transition state, and paste your own keyframes when you are ready to go beyond the defaults.

Preset Library

Animation examples you can load instantly

Use the library as a quick CSS animation examples gallery, then fine-tune the generated motion with the controls below.

Animation Controls

Tune the animation shorthand

These controls map directly to animation-name, animation-duration, timing-function, delay, iteration-count, direction, and fill-mode.

animation-name

Switch to custom when you want the textarea rule to drive the preview.

Preview element

Swap between a box, circle, or text-style target.

Transforms + Transitions

Control the interactive state

Click the preview element to toggle the transition state. The transform sliders define the active state values.

Custom Keyframes

Write your own @keyframes

Paste a complete @keyframes rule below. The playground will read the animation name and use it when you switch to the custom option.

Live Preview

Bounce

A classic vertical bounce with a soft landing.

Tip: tap the element in the stage to compare the base state and the transition state without leaving the preview.

Generated CSS

Copy the code

The output below updates with every control so you can move from exploration to implementation without rewriting anything.

  0%, 20%, 53%, 80%, 100% {
    transform: translateY(0);
  }

  40%, 43% {

  }

  70% {
    transform: translateY(-14px);
  }

  90% {
    transform: translateY(-4px);
  }
}

How to use this CSS animation generator

Choose a preset animation

Pick bounce, spin, fade, wobble, slide, or another preset to load a ready-made keyframe example.

Tune timing and repetition

Change duration, delay, direction, fill mode, and timing function until the motion feels right.

Preview transforms and transitions

Toggle the live state to test translate, rotate, scale, skew, and transition properties on the same element.

Write custom keyframes and copy the CSS

Paste your own @keyframes rule, switch to the custom option, then copy the generated CSS into your project.

Frequently asked questions

Common questions about CSS animations, transitions, timing functions, and custom keyframes.

What is a CSS animation playground?

A CSS animation playground is an interactive editor where you change animation properties and see the result immediately. It helps you learn CSS animations faster because duration, timing, keyframes, and transforms update in real time instead of after a page refresh.

What is the difference between CSS animations and CSS transitions?

CSS animations can run through multiple keyframe stages on their own, while CSS transitions animate between a start state and an end state after a trigger such as hover, focus, or a class change. This playground shows both so you can compare when each technique is a better fit.

When should I use a custom cubic-bezier() timing function?

Use a custom cubic-bezier() timing function when the built-in easing keywords do not match the feel you want. It is especially useful for overshoot, snappy entrances, or motion that needs to match a product brand or interaction style.

Can I write my own @keyframes in this CSS animation generator?

Yes. The custom keyframes editor accepts a full @keyframes rule, and the playground will use the animation name it finds in your code. That makes it useful for testing custom motion patterns before adding them to a production stylesheet.

What does animation-fill-mode do?

animation-fill-mode controls whether an element keeps styles from the first or last keyframe before or after the animation runs. For example, forwards keeps the final frame applied, while backwards applies the first frame during the delay period.
