文字

语法：

animation：<single-animation>[,<single-animation>]*

<single-animation> = <single-animation-name> || <time> || <single-animation-timing-function> || <time> || <single-animation-iteration-count> || <single-animation-direction> || <single-animation-fill-mode> || <single-animation-play-state>

默认值：看每个独立属性

适用于：所有元素，包含伪对象:after和:before

继承性：无

动画性：否

计算值：看每个独立属性

媒体：视觉

取值：

  • <' animation-name '>：检索或设置对象所应用的动画名称

  • <' animation-duration '>：检索或设置对象动画的持续时间

  • <' animation-timing-function '>：检索或设置对象动画的过渡类型

  • <' animation-delay '>：检索或设置对象动画延迟的时间

  • <' animation-iteration-count '>：检索或设置对象动画的循环次数

  • <' animation-direction '>：检索或设置对象动画在循环中是否反向运动

  • <' animation-fill-mode '>：检索或设置对象动画时间之外的状态

  • <' animation-play-state '>：检索或设置对象动画的状态。w3c正考虑是否将该属性移除，因为动画的状态可以通过其它的方式实现，比如重设样式

说明：

复合属性。检索或设置对象所应用的动画特效。

  • 如果提供多组属性值，以逗号进行分隔。

  • 注意：如果只提供一个<time>参数，则为 <' animation-duration '> 的值定义；如果提供二个<time>参数，则第一个为 <' animation-duration '> 的值定义，第二个为 <' animation-delay '> 的值定义

  • 对应的脚本特性为animation。

兼容性：

  1. 在一些场景中会有错误行为

  2. 部分浏览器不支持伪元素动画，或者支持得不够好，尽可能不要利用伪元素来做动画
