HTML Style animationDuration用法及代码示例

HTML DOM中的Style animationDuration属性用于设置完成一个动画周期的时间间隔。

用法:

它返回animationDuration属性。
```
object.style.animationDuration
```

它设置animationDuration属性。

object.style.animationDuration = "time|initial|inherit"

属性值：

time:它用于指定动画将完成一个周期的时间长度。默认值为0，即不显示动画。
initial:它用于将样式animationDuration属性设置为其默认值。
inherit:它从其父级继承样式animationDuration属性。

供应商前缀：为了使浏览器兼容，许多Web开发人员通过使用扩展名来添加browser-specific属性，这些扩展名包括-webkit-(用于Safari，Google Chrome和Opera)，-ms-(用于Internet Explorer，-moz-(用于Firefox)，-o-(用于旧版本的Opera))等等。如果浏览器不支持任何扩展名，它将直接忽略它。

                /*For Chrome, Safari, Opera browsers */ 
                /* animation name geeks */ 
                /* infinite animation iteration */ 
                -webkit-animation:geeks 5s infinite;
