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