CSS3 animation-timing-function 属性

实例

从开始到结束以相同的速度播放动画:

animation-timing-function:linear;
-webkit-animation-timing-function:linear; /* Safari and Chrome */

尝试一下 »
在此页底部有更多的例子。

浏览器支持

Internet ExplorerFirefoxOperaGoogle ChromeSafari

Internet Explorer 10, Firefox, 和 Opera支持 animation-timing-function 属性.

Safari和Chrome通过私有属性-WebKit-animation-timing-function支持。

注意: Internet Explorer 9及更早IE版本不支持animation-timing-function属性。


标签定义及使用说明

animation-timing-function指定动画将如何完成一个周期。

速度曲线定义动画从一套 CSS 样式变为另一套所用的时间。

速度曲线用于使变化更为平滑。

默认值:ease
继承:no
版本:CSS3
JavaScript 语法:object object.style.animationTimingFunction="linear"


语法

animation-timing-function: value;

animation-timing-function使用的数学函数,称为三次贝塞尔曲线,速度曲线。使用此函数,您可以使用您自己的值,或使用预先定义的值之一:

描述测试
linear动画从头到尾的速度是相同的。测试
ease默认。动画以低速开始,然后加快,在结束前变慢。测试
ease-in动画以低速开始。测试
ease-out动画以低速结束。测试
ease-in-out动画以低速开始和结束。测试
cubic-bezier(n,n,n,n)在 cubic-bezier 函数中自己的值。可能的值是从 0 到 1 的数值。

提示: 请试着在下面的"尝试一下"功能中使用不同的值。

实例

为了更好地理解不同的定时函数值,这里提供了设置五个不同值的五个不同的 div 元素:

/* W3C and Opera: */
#div1 {animation-timing-function: linear;}
#div2 {animation-timing-function: ease;}
#div3 {animation-timing-function: ease-in;}
#div4 {animation-timing-function: ease-out;}
#div5 {animation-timing-function: ease-in-out;}
/* Firefox: */
#div1 {-moz-animation-timing-function: linear;}
#div2 {-moz-animation-timing-function: ease;}
#div3 {-moz-animation-timing-function: ease-in;}
#div4 {-moz-animation-timing-function: ease-out;}
#div5 {-moz-animation-timing-function: ease-in-out;}
/* Safari and Chrome: */
#div1 {-webkit-animation-timing-function: linear;}
#div2 {-webkit-animation-timing-function: ease;}
#div3 {-webkit-animation-timing-function: ease-in;}
#div4 {-webkit-animation-timing-function: ease-out;}
#div5 {-webkit-animation-timing-function: ease-in-out;}

实例

与上例相同,但是通过 cubic-bezier 函数来定义速度曲线:

/* W3C and Opera: */
#div1 {animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Firefox: */
#div1 {-moz-animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-moz-animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-moz-animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-moz-animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-moz-animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Safari and Chrome: */
#div1 {-webkit-animation-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-webkit-animation-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-webkit-animation-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-webkit-animation-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-webkit-animation-timing-function: cubic-bezier(0.42,0,0.58,1);}
