# CSS3 @keyframes Rule

« CSS Reference
animation Property »

## Example

Make a div element move gradually 200px down:

@keyframes mymove
{
from {top:0px;}
to {top:200px;}
}
@-webkit-keyframes mymove /* Safari and Chrome */
{
from {top:0px;}
to {top:200px;}
}
Try it yourself »
More examples at the bottom of this page.

## Browser Support

The @keyframes rule is supported in Internet Explorer 10, Firefox, and Opera.

Safari and Chrome support an alternative, the @-webkit-keyframes rule.

Note: The @keyframes rule is not supported in Internet Explorer 9 and earlier versions.

## Definition and Usage

With the @keyframes rule, you can create animations.

The animation is created by gradually changing from one set of CSS styles to another.

During the animation, you can change the set of CSS styles many times.

Specify when the change will happen in percent, or the keywords "from" and "to", which is the same as 0% and 100%.
0% is the beginning of the animation, 100% is when the animation is complete.
For best browser support, you should always define both the 0% and the 100% selectors.

Note: Use the animation properties to control the appearance of the animation, and also to bind the animation to selectors.

## Syntax

@keyframes animationname {keyframes-selector {css-styles;}}

Value | Description
--- | ---
animationname | Required. Defines the name of the animation.

keyframes-selector

Required. Percentage of the animation duration.

Legal values:

0-100%
from (same as 0%)
to (same as 100%)

Note: You can have many keyframes-selectors in one animation.

css-styles | Required. One or more legal CSS style properties

## Try it Yourself - Examples

## Example

Add many keyframe selectors in one animation:

@keyframes mymove
{
0% {top:0px;}
25% {top:200px;}
50% {top:100px;}
75% {top:200px;}
100% {top:0px;}
}
@-webkit-keyframes mymove /* Safari and Chrome */
{
0% {top:0px;}
25% {top:200px;}
50% {top:100px;}
75% {top:200px;}
100% {top:0px;}
}
Try it yourself »

## Example

Change many CSS styles in one animation:

@keyframes mymove
{
0% {top:0px; background:red; width:100px;}
100% {top:200px; background:yellow; width:300px;}
}
@-webkit-keyframes mymove /* Safari and Chrome */
{
0% {top:0px; background:red; width:100px;}
100% {top:200px; background:yellow; width:300px;}
}
Try it yourself »

## Example

Many keyframe selectors with many CSS styles:

@keyframes mymove
{
0% {top:0px; left:0px; background:red;}
25% {top:0px; left:100px; background:blue;}
50% {top:100px; left:100px; background:yellow;}
75% {top:100px; left:0px; background:green;}
100% {top:0px; left:0px; background:red;}
}
@-webkit-keyframes mymove /* Safari and Chrome */
{
0% {top:0px; left:0px; background:red;}
25% {top:0px; left:100px; background:blue;}
50% {top:100px; left:100px; background:yellow;}
75% {top:100px; left:0px; background:green;}
100% {top:0px; left:0px; background:red;}
}
