How to Use CSS Animation Generator

  1. 1

    Name your animation and set timing

    Enter a unique animation name (e.g., 'slideIn'). Set duration (how long the animation runs) and delay (wait before starting). These appear in the CSS output.

  2. 2

    Configure animation behavior

    Choose timing function (ease-in-out for smooth, linear for constant speed), iteration count (1, 3, or infinite), direction (normal, reverse, alternate), and fill mode (forwards to hold final state).

  3. 3

    Start with a preset or build custom keyframes

    Click a preset (bounce, fade, slide, pulse, shake) to populate default keyframes instantly. Or manually define keyframes by editing percentages (0%, 50%, 100%) and CSS properties (transform, opacity, color).

  4. 4

    Preview animation in real-time

    Watch the gradient square animate with your settings in the live preview. Adjust sliders, timing functions, or keyframes and see changes instantly—no page reload needed.

  5. 5

    Copy CSS and apply to your project

    Copy the full CSS output (both @keyframes and animation property). Paste into your stylesheet, add the animation class to elements, and deploy. Works on all modern browsers.

Frequently Asked Questions

What are CSS keyframes?
CSS keyframes define the styles at specific points during a CSS animation. You specify percentage points (0%, 50%, 100%) and the CSS properties that should apply at each point. The browser interpolates between keyframes to create smooth animations.
What's the difference between duration and delay?
Duration is how long the animation takes to complete (1s, 2s, etc.). Delay is how long to wait before starting the animation. For example: duration=2s, delay=1s means the animation will wait 1 second, then play for 2 seconds.
What do animation presets do?
Presets are pre-configured keyframe sets that create common animation effects: bounce (up/down motion), fade (opacity change), slide (horizontal movement), pulse (opacity fade), and shake (vibration effect). Click any preset to instantly apply its keyframes and timing.
Can I use these animations on all elements?
Yes. Once you generate the CSS, copy it and paste into your stylesheet. Apply the animation class to any HTML element. Works on divs, buttons, images, text, and any other element. The animation property is standard CSS supported by all modern browsers.
Is this tool free and does it store my data?
Yes. Free to use. All CSS generation happens in your browser. No data is sent to servers or stored. You fully own the generated CSS code. The tool is entirely client-side with zero backend dependencies.
