How to Use CSS Keyframes & Animation Generator

Select a Preset or Add Keyframes

Choose a baseline animation preset (Bounce, Pulse, Spin) or start adding custom keyframe steps along the timeline.

Tune Transforms & Timing

Adjust Translate X/Y, Scale, Rotate, and Opacity sliders for each step, and set global duration and easing curves.

Copy CSS or Tailwind Config

Inspect the generated @keyframes rules, test playback on the live stage, and copy the pure CSS or Tailwind snippet.

Worked example: Pulse Preset to Keyframes and Animation CSS

The engine composes transform parts, sorts keyframe steps, and emits the keyframes block plus animation shorthand.

Animation Config Source

preset: pulse - scale 1 to 1.15, opacity 1 to 0.85, duration 1.5s, infinite

Compiled Keyframes CSS Processed

@keyframes pulse { 0% { transform: scale(1); } 50% { transform: scale(1.15); } 100% { transform: scale(1); } }

Frequently Asked Questions

Does this generator support Tailwind CSS?

Yes! Switch to the Tailwind CSS tab to instantly generate the exact theme.extend keyframes and animation configuration snippet for tailwind.config.js.

Why are CSS transforms preferred over position properties for animations?

CSS transforms (translateX, translateY, scale, rotate) and opacity are processed directly by the GPU compositor, avoiding expensive browser layout and paint reflows for smooth 60 FPS performance.

Can I loop the animation infinitely?

Yes. Set the Iterations dropdown to 'Infinite (Loop)', or specify exact iteration counts (1, 2, 3, or 5 times) with forwards/backwards fill modes.

How do I use the generated CSS in my project?

Click 'Copy CSS' and paste the @keyframes and .animate- class into your stylesheet, then add the class to any HTML element you wish to animate.

Is any code or animation data sent to an external server?

No. The entire animation editor, math compiler, and preview stage execute 100% locally in your web browser memory.
