CSS Animation Generator Tool
Custom keyframe builder, cubic-bezier editor, scrubber — features most CSS animation generators skip
Most online CSS animation generators let you pick a preset and copy the code. This tool adds a custom keyframe builder where you define your own percentage stops and transform values, an interactive cubic-bezier curve editor with drag control points, and a scrubber to inspect any frame of the animation.
How to generate CSS keyframe animations
CSS animation properties explained
| Property | Values | What it controls |
|---|---|---|
| animation-duration | 1s, 500ms, 2.5s | Total time for one cycle of the animation |
| animation-delay | 0s, 0.5s, -1s | Time before animation starts (negative = start partway through) |
| animation-timing-function | ease, linear, cubic-bezier() | The pace curve — how properties change over time within each keyframe interval |
| animation-iteration-count | 1, 3, infinite | How many times the animation plays |
| animation-direction | normal, reverse, alternate | Whether each cycle runs forward, backward, or alternates |
| animation-fill-mode | none, forwards, backwards, both | Whether element retains animation styles before start or after end |
| animation-play-state | running, paused | Toggles the animation on/off — useful for pause-on-hover |
| @keyframes | 0%, 50%, 100%, from, to | Defines property values at specific points along the animation timeline |
CSS Keyframe Animation — A Complete Guide for Developers
CSS animations let you animate HTML elements by transitioning between a sequence of style states — called keyframes — over time. Unlike CSS transitions, which only animate between two states when triggered by user interaction, @keyframes animations can define multiple intermediate states, run automatically when the page loads, loop indefinitely, and reverse direction. Used correctly, they create polished micro-interactions, entrance effects, loading states and attention-grabbing UI elements without any JavaScript.

The @keyframes rule defines the animation sequence. Each percentage stop (0%, 25%, 50%, 100%) or keyword (from, to) specifies what CSS properties the element should have at that point in the animation. The browser automatically interpolates (tweens) between the keyframe values to create a smooth motion. The animation property — applied to the element — binds the @keyframes rule to the element and controls its duration, timing, repetition and behaviour.

Writing @keyframes by hand requires knowing exact property names and values, calculating transform sequences mentally, and constantly switching between editor and browser to see the result. A visual animation maker closes this loop: you adjust sliders and see the preview update immediately, without any save-and-refresh cycle. The cubic-bezier editor is particularly valuable — instead of guessing values for a custom timing curve, you drag control points and see exactly how the easing shape changes the animation’s feel in real time.

The most frequently used animation effects in web design are: Fade (opacity 0→1 or 1→0) for entrances and exits. Slide (translateX or translateY) for elements entering from an edge. Bounce (translateY with overshoot at 40% and 60%) for playful attention effects. Spin (rotate 0deg→360deg) for loading indicators. Pulse (scale 1→1.05→1) for drawing attention to a badge or notification dot. All of these use only transform and opacity, which are GPU-accelerated and do not trigger layout recalculation — the key performance principle for smooth 60fps animations.
CSS animation code generator with cubic-bezier
The timing function is one of the most powerful and underused tools in CSS animation. ease (the default) starts slow, accelerates, then decelerates — it works for most UI animations. linear moves at constant speed and is ideal for continuous rotations. ease-in accelerates through the animation — used for elements leaving the screen. ease-out decelerates — ideal for elements arriving. cubic-bezier() gives you full control over the acceleration curve: the four values define two control points on a bezier curve. Material Design’s standard easing is cubic-bezier(0.4, 0, 0.2, 1) — a fast departure and gradual arrival that feels natural and responsive.

The @keyframes rule follows this exact structure: @keyframes animation-name { percentage { CSS properties } }. The name is arbitrary and referenced in the animation property. Percentages can be any value from 0% to 100%, and multiple percentages can share the same declaration block (e.g., “0%, 100% { opacity: 1; }”). The from keyword is equivalent to 0%, and to is equivalent to 100%. Only properties that are interpolatable (numeric or colour values) can be animated — display, visibility and similar properties switch abruptly rather than animating.
