CSS3 @keyframes Rule


Example

Make an element move gradually 200px down:

/* Chrome, Safari, Opera */
@-webkit-keyframes mymove {
    from {top: 0px;}
    to {top: 200px;}
}

/* Standard syntax */
@keyframes mymove {
    from {top: 0px;}
    to {top: 200px;}
}

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.


Browser Support

The numbers in the table specifies the first browser version that fully supports the rule.

Numbers followed by -webkit-, -moz- or -o- specifies the first version that worked with a prefix.

@keyframes 4.0 -webkit- 10.0 16.0
