Can I customize the animation further after copying the code?

Absolutely — the output is plain CSS text you can freely edit by hand (renaming the animation, adding extra steps) after pasting it into your project.

CSS Keyframe Animation Generator

The CSS Keyframe Animation Generator lets you pick an animation type from 12 ready-made styles (fade in/out, slide in from all four directions, zoom in/out, bounce in, rotate in, flip on the X or Y axis), then adjust duration, delay, timing function, and iteration count, with a live preview and a Replay button. Copy the complete @keyframes rule plus a ready-to-use animation class. All generation happens in your browser — nothing is ever uploaded to a server.

What this tool does

Generates ready CSS animation code from an animation type you choose — fade, slide, zoom, bounce, rotate and flip — with duration, delay, timing function and iteration count.

When to use it

An element you want to animate in on page load.
A notification or modal you want to slide into place.
A repeating animation to draw attention to an element.
Learning how CSS animation code is structured.

How to use it

Choose the "Animation type".
Set the "Duration", "Delay", "Timing function" and "Iteration count".
Copy the generated code.

A practical example

Input

A slide-in-from-left animation at a short duration, playing once.

Output

Keyframes plus the animation properties, ready to apply to an element.

Limitations

Many or long animations make a page feel slower; brief motion serves the experience while lengthy motion obstructs it.
Some users enable a reduced-motion preference in their system for health reasons — respecting that preference is your responsibility in your own code, and the tool does not add it automatically.
An infinite animation consumes rendering resources continuously.
The code is the animation itself; triggering it on an event needs additional code.

Privacy and processing

The code is generated entirely in your browser and nothing is ever sent to a server.

Technical notes

Separating duration, delay, timing function and iteration count in the interface mirrors how CSS separates them, so you know which property to adjust later.
