What is a CSS Animation Generator?
A visual tool that builds CSS @keyframes animations without writing them by hand.
A CSS animation generator lets you design a keyframe animation visually and
produces the exact CSS to reproduce it. Instead of writing @keyframes blocks by
hand, guessing at percentages, and reloading the browser to check the result, you build the
animation incrementally, see it play in a live preview, and copy the finished CSS in one click.
This generator supports multiple animations in a single project. Build a library of named animations — a fade-in for your hero, a slide-up for your cards, a pulse for your notification badge — and copy them all at once. Every animation keeps its own keyframes, timing and target selector, and the generated CSS includes every animation in the library.
Inar CSS Animation Generator runs entirely inside your browser. Your animations never leave your device — there is no upload, no server call and no third-party processing.
Anatomy of a CSS Animation
Three moving parts: the keyframes, the properties, and the timing.
Keyframes
A @keyframes block defines what the element looks like at each stage of the animation. Each stage is a percentage between 0% and 100% — or the keywords from and to, which mean the same thing as 0% and 100%.
Properties
Each keyframe declares one or more CSS properties. The browser interpolates between them. Not every property can be animated — transform, opacity and background-color are the safest and most performant choices.
Timing
The animation shorthand controls the pacing: duration, delay, timing-function, iteration-count, direction and fill-mode. These are set once on the target selector.
Features
Everything you need to design an animation library without leaving the browser.
Multi-animation library
Build, name, duplicate and switch between multiple animations in a single project. Each has its own keyframes and timing.
Live preview
A demo box plays the active animation in real time as you adjust keyframes, timing and duration.
Visual timeline
A draggable timeline shows keyframe positions and lets you scrub through the animation frame by frame.
Keyframe editor
Add, delete and reorder keyframes. Each has its own transform, opacity and background-color controls.
90+ presets
Ten categories: fade, slide, transform, attention, entrance, color, loading, UI, text and marquee.
Copy all CSS
Copy the entire library at once, or switch to a specific animation and copy just that one.
Full timing control
Duration, delay, iteration count, direction, fill mode, play state and 12 timing functions.
Live statistics
Keyframe count, property count, library totals, byte size and property distribution charts.
Download
Export your entire animation library as a single .css file.
Session persistence
Your entire library is saved to local storage between visits.
Keyboard-first
Download with Ctrl+S, copy with Ctrl+Shift+C.
Privacy first
100% client-side. Your animations never leave your browser.
How to Use the Generator
Five steps from a blank canvas to a full animation library.
Load your first animation
Pick a preset from the Presets tab or start from the default. It appears in the Animation library panel at the top left.
Build a library
Click New animation to add another animation to the project. Duplicate existing ones from their card menu. Each animation gets its own name, keyframes and timing.
Configure the active animation
Select an animation in the library to make it active. The preview, settings panel and keyframe editor all bind to whichever animation is currently selected.
Preview and refine
Play, pause, restart and scrub through each animation. Drag the speed slider from 0.1× to 3× to inspect the motion.
Export the whole library
Click Copy all CSS to grab every animation in the project as one stylesheet, or Download to save it as
animations.css.
Animation Tips
Small details that make an animation feel professional.
Animate transform, not position
Changing left or top forces the browser to recalculate layout on every frame. transform: translate() runs on the compositor and stays at 60 fps.
Match the timing to the motion
Ease-out for elements entering the viewport. Ease-in for elements leaving. Ease-in-out for anything bouncing or looping. Linear only for continuous motion like a spinner.
Keep durations short
Most UI animations should run between 150 ms and 400 ms. Anything longer feels sluggish. Reserve 800 ms and up for hero animations and page transitions.
Frequently Asked Questions
Answers to the most common questions about CSS animations.
Can I build multiple animations in one project?
Yes. Use the Animation library panel to add, duplicate and switch between named animations. Every animation keeps its own keyframes, timing and target selector, and the generated CSS includes all of them.
What is the difference between CSS animations and transitions?
A transition animates between two states and needs a trigger such as hover or a class change. An animation runs on its own using @keyframes and can have as many intermediate stages as you like.
Which properties can be animated?
Most properties with numeric or color values can be animated, but the safest and most performant are transform, opacity and filter. Avoid animating width, height and position — they force layout recalculations.
Why does my animation not start?
The most common cause is forgetting to apply the animation to a selector. An animation only runs when its name is referenced by a target rule's animation-name or animation shorthand.
What does fill-mode do?
It controls how the animation applies styles outside of its active duration. forwards keeps the final keyframe's styles after the animation ends. backwards applies the first keyframe's styles during the delay. both does both.
What does iteration-count: infinite mean?
The animation repeats forever. Use a finite number like 1 or 3 for animations that should play a specific number of times and then stop.
Can I use multiple animations on one element?
Yes. Provide comma-separated animation names and settings: animation: fade 1s, slide 2s;. Each animation runs independently.
How do I respect prefers-reduced-motion?
Wrap animations in a media query: @media (prefers-reduced-motion: reduce) { .animated { animation: none; } }. This disables motion for users who have requested reduced animation in their OS settings.
Are CSS animations performant?
When they animate transform, opacity or filter, yes — they run on the GPU at 60 fps. Animating layout-triggering properties such as width or top can cause jank.
Is the CSS Animation Generator free?
Yes. It is completely free to use, with no account, no sign-up and no usage limits.
