Free CSS Animation & Keyframes Generator
Create CSS keyframe animations visually and copy the code in one click. Choose from fade, slide, zoom, bounce, spin, pulse, and shake effects, set duration, delay, timing, and iterations, and preview it live — then paste the @keyframes and animation CSS into your project. Free and JavaScript-free output.
What are CSS keyframe animations?
CSS animations let you move, fade, scale, and rotate elements over time using @keyframes rules — no JavaScript required. A @keyframes block defines the states an element passes through (for example, from invisible to visible), and the animation properties control how long it takes, when it starts, and how many times it repeats. They run smoothly on the GPU and are the standard way to add motion to modern interfaces.
The animation properties you control
This generator sets the properties you apply to your element:
- animation-name — links to your @keyframes rule.
- animation-duration — how long one cycle takes.
- animation-delay — how long to wait before it starts.
- animation-timing-function — the easing (ease, linear, ease-in-out, and more).
- animation-iteration-count — how many times it runs, including infinite.
- animation-fill-mode — keeps the element in its final state after finishing.
How to use the animation generator
It is fully interactive:
- Pick an animation style and watch it preview instantly.
- Adjust duration, delay, timing function, and iteration count.
- Press Replay to see it again with your settings.
- Copy the CSS — it includes both the @keyframes and the animation class.
How to apply the animation
Paste the generated CSS into your stylesheet, then add the animate class to any element you want to animate — for example a hero heading, a card, or a button. For entrance animations, animation-fill-mode: both (already included) keeps the element hidden before it starts and holds its final state after, preventing the flicker you get without it. To trigger animations on scroll or click, add the class with JavaScript at the right moment.
Performance and best practices
For smooth 60fps motion, animate transform and opacity wherever possible — these are the properties browsers can accelerate on the GPU, unlike width, height, or margins, which force expensive layout recalculations. Keep entrance animations short (200–500ms), use easing that feels natural, and respect users who prefer reduced motion by wrapping non-essential animations in a prefers-reduced-motion media query.
Pro tip
Stagger a list or grid by giving each item an increasing animation-delay — even 60–100ms apart — so elements cascade in rather than appearing all at once. Combine this with a custom easing from our Cubic-Bezier Generator for motion that feels uniquely yours.
