CSS Animation Generator

What is a CSS Animation Generator?

CSS animations bring interfaces to life by transitioning elements through a series of keyframes — without JavaScript. Writing the @keyframes rules and tuning the animation properties by hand can be tedious. An animation generator gives you presets and controls, then outputs the complete CSS.

Our CSS Animation Generator offers common animation presets and lets you adjust duration, timing function, and iteration count, with a live preview you can replay so you see exactly how the motion feels before copying the code.

How to Generate an Animation

• Pick a preset: fade, slide, bounce, spin, pulse, or shake
• Set the duration in seconds
• Choose a timing function like ease, linear, or ease-in-out
• Set it to loop infinitely or run a specific number of times
• Copy the @keyframes and animation CSS, and use Replay to preview again

Understanding Animation Properties

An animation needs a @keyframes rule that defines the states, and an animation property that applies it. Duration controls how long one cycle takes. The timing function shapes the acceleration — ease feels natural, linear is constant, and ease-in-out starts and ends gently.

Iteration count determines how many times the animation runs; infinite loops it forever, which suits spinners and pulsing indicators. For entrance effects like fade and slide, a single run is usually what you want.

Using Animations Effectively

Subtle, purposeful animation guides attention and adds polish — fading content in, sliding panels into view, or pulsing a notification. Overdone animation distracts and can cause discomfort, so use motion intentionally and keep durations short for UI feedback. Consider users who prefer reduced motion. This tool generates standard CSS you can adapt, entirely in your browser.
