CSS Animation Generator
Generate CSS @keyframe animations visually
CSS Animation Generator builds a complete @keyframes block plus the animation shorthand property for six common effects — fade, slide-up, slide-in, bounce, spin, and pulse — with your chosen duration, easing, and repeat count.
How to use CSS Animation Generator
- 1
Choose an animation type (fade, slide, bounce, spin, or pulse).
- 2
Set the duration, easing, and how many times it repeats.
- 3
Copy the generated @keyframes and animation CSS.
- 4
Apply the animation name to your element's class.
Everything you need to know about CSS animations
What is a CSS @keyframe animation?
@keyframes define how an element's styles change over the course of an animation — its position, opacity, size, or rotation at different points in time — letting the browser handle the smooth transition between those points without any JavaScript.
When you actually need this
- Loading spinners and skeleton states, giving visual feedback while content loads.
- Attention-drawing micro-interactions — a subtle pulse, bounce, or fade on an important element.
- Page transition effects as content enters or leaves the viewport.
Less is usually more
Fast, subtle animations (a couple hundred milliseconds) generally feel more polished than long, elaborate ones — an animation that draws attention to itself rather than to the content it's supporting has usually gone too far.

Frequently Asked Questions
What's the difference between slide-up and slide-in?
slide-up animates the element moving upward into place (translateY), while slide-in moves it in from the left (translateX) — pick based on which direction fits your layout.
What does the iteration count control?
How many times the animation plays — set it to a number for a fixed count, or "infinite" for an animation that loops forever, like the spin or pulse effects commonly used for loading indicators.
Do I need to write any JavaScript to use this?
No — it's pure CSS. Paste the generated @keyframes block into your stylesheet and apply the animation property to whichever element you want animated.
Does this tool send my settings to a server?
Yes — they're sent to our servers to build the CSS and the result is returned to you; nothing is stored.
Is this tool free to use?
Yes — completely free, with no signup required.
