CSS Animation Generator
Create @keyframes CSS animations with a visual builder. Choose from presets, customize timing and easing, and generate production-ready CSS code.
How to Use the CSS Animation Generator
1
Choose Your Animation
Select from 17 preset animations like Bounce, Fade In, Slide, or Zoom. Each preset has professionally designed @keyframes ready to use. Select "Custom" to create your own animation from scratch.
2
Customize Timing & Behavior
Adjust duration (0.1s to 10s), timing function (ease, linear, cubic-bezier), delay, direction, fill mode, and iteration count. Toggle Infinite for endless looping. Watch the preview update in real time.
3
Copy the Generated CSS
Click Copy CSS to copy the complete @keyframes rule and animation property. Paste the code directly into your stylesheet and apply it to any HTML element.
CSS Animation Properties Reference
| Property | Values | Description |
|---|---|---|
animation-name | @keyframes name | Specifies the name of the @keyframes animation to apply |
animation-duration | Time in s or ms | Sets how long one full animation cycle takes to complete |
animation-timing-function | ease, linear, ease-in, ease-out, ease-in-out, cubic-bezier(), steps() | Controls the speed curve of the animation between keyframes |
animation-delay | Time in s or ms | Delays the start of the animation. Negative values start the animation mid-cycle |
animation-iteration-count | Number or infinite | Determines how many times the animation plays |
animation-direction | normal, reverse, alternate, alternate-reverse | Sets whether the animation plays forward, backward, or alternates |
animation-fill-mode | none, forwards, backwards, both | Defines styles applied before the animation starts and after it ends |
animation-play-state | running, paused | Pauses or resumes a running animation without resetting it |
animation (shorthand) | Combines all animation properties in one declaration | Order: name, duration, timing-function, delay, iteration-count, direction, fill-mode, play-state |
Frequently Asked Questions
CSS animation allows elements to transition between different style states over time using @keyframes rules. You define keyframes with percentage positions (0% to 100%) that specify styles at each stage of the animation, then apply the animation to an element using the animation property.
Transitions only animate between two states (start and end) when triggered, like hover. Animations support multiple intermediate keyframes, can loop infinitely, play in reverse, and run automatically without a trigger. Animations give you more control over timing, direction, and fill modes.
@keyframes defines the stages of an animation using percentage selectors. 0% is the start state and 100% is the end state. You can add intermediate stops like 25% or 50% to create complex multi-step animations. Each keyframe block contains CSS property declarations that are applied at that point in the animation cycle.
CSS provides several built-in timing functions: ease (slow start and end), ease-in (slow start), ease-out (slow end), ease-in-out (slow start and end, more pronounced than ease), and linear (constant speed). You can also create custom bezier curves with cubic-bezier(n,n,n,n) for precise control.
Set animation-iteration-count to infinite. You can also use animation-direction: alternate to make the animation play forward then backward, creating a seamless looping effect. Combine infinite with alternate for smoother repeating animations like pulsing or floating effects.
