CSS Animation Generator

Builds @keyframes animations visually. Pick a preset or define keyframe stops, tweak duration/delay/timing/direction, preview live, and copy CSS/SCSS/Tailwind.

Yes. Select cubic-bezier (custom) and a visual curve editor appears with x1/y1/x2/y2 inputs. The resulting value is applied to both the live preview and the generated code.

Emits a tailwind.config.js snippet extending theme.keyframes/animation for animate-<name> utilities. The raw @keyframes CSS is included as a fallback.

A CSS transition animates a property between two states and only runs in response to a trigger, such as a hover or a class change, moving smoothly from the old value to the new one. A CSS animation uses @keyframes to define many intermediate steps along a timeline and can run on its own as soon as the element loads, loop forever, reverse, or alternate direction. Transitions are best for simple one-off state changes like a button color fade, while animations handle multi-step motion such as a bounce, a spinner, or a sequence that touches several percentages between 0% and 100%. This generator builds the @keyframes route, letting you define each stop, set timing and iteration, preview it live, and copy clean CSS, SCSS, or Tailwind code.

By default a CSS animation only styles an element while it is playing; before it starts and after it ends, the element snaps back to its normal styles. The fill-mode property changes that. "forwards" keeps the element on its last keyframe (100%) after the animation finishes, so a fade-in stays visible instead of disappearing. "backwards" applies the first keyframe (0%) during any delay before playback begins, preventing a flash of the un-animated state. "both" combines the two, holding the start frame during the delay and the end frame afterward, which is the safest choice for entrance effects. "none" disables all of this. Pick the wrong mode and your element flickers at the edges of playback. The generator exposes all four values, so you can toggle fill mode and watch the live preview react before copying the code.

Set the iteration count to "infinite" instead of a fixed number. The iteration count tells the browser how many times to play the @keyframes from start to finish; a value of 1 plays once, 3 plays three times, and "infinite" repeats endlessly until the element is removed or the animation is paused. For a smooth, never-ending spinner you also want a "linear" timing function so each rotation runs at a constant speed with no easing at the loop seam, plus a single keyframe that rotates from 0 to 360 degrees. The Spin preset in this generator already wires that up, but you can apply the same infinite count to any preset to create pulsing, wobbling, or breathing effects. Set iteration to infinite, pick linear easing if you need seamless looping, preview it, and copy the result.

A cubic-bezier timing function controls how an animation accelerates and decelerates over its duration, and it is defined by two control points written as x1, y1, x2, y2. The x values must stay between 0 and 1 because they represent progress through time, while the y values can go below 0 or above 1 to create overshoot or anticipation effects, like a value that springs past its target before settling. The first point shapes how the motion eases in at the start; the second shapes how it eases out at the end. The familiar named easings are just presets: ease-in is roughly cubic-bezier(0.42, 0, 1, 1), for example. This tool's visual curve editor lets you drag or type all four numbers and redraws the curve and live preview instantly, so you can fine-tune the feel before copying it.

That snap-back happens because, by default, an animation stops styling the element the moment it completes, so the element reverts to whatever its base CSS says. If your 0% keyframe sets opacity to 0 and the element's normal state is also invisible, a finished fade-in will vanish. The fix is animation-fill-mode: use "forwards" so the element holds its 100% keyframe after the animation ends, or "both" to also cover any start delay. A jump at the start of a loop usually means your 0% and 100% keyframes do not match, so the timeline cannot continue seamlessly. The generator helps you catch both problems: set a fill mode, align your first and last stops, and use the Replay button to watch the transition repeatedly until it is clean before copying the CSS.
