CSS3 transition-timing-function 属性


实例

转场效果以同样的速度从开始到结束:

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


浏览器支持

Internet ExplorerFirefoxOperaGoogle ChromeSafari

Internet Explorer 10, Firefox, Chrome和 Opera支持transition-timing-function 属性

Safari 通过私有属性 -webkit-transition-timing-function 支持。

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


属性定义及使用说明

transition-timing-function属性指定切换效果的速度。

此属性允许一个过渡效果,以改变其持续时间的速度。

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


语法

transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-bezier(n,n,n,n);

描述
linear 规定以相同速度开始至结束的过渡效果(等于 cubic-bezier(0,0,1,1))。
ease 规定慢速开始,然后变快,然后慢速结束的过渡效果(cubic-bezier(0.25,0.1,0.25,1))。
ease-in 规定以慢速开始的过渡效果(等于 cubic-bezier(0.42,0,1,1))。
ease-out 规定以慢速结束的过渡效果(等于 cubic-bezier(0,0,0.58,1))。
ease-in-out 规定以慢速开始和结束的过渡效果(等于 cubic-bezier(0.42,0,0.58,1))。
cubic-bezier(n,n,n,n) 在 cubic-bezier 函数中定义自己的值。可能的值是 0 至 1 之间的数值。

Tip: Try the different values in the examples below to understand how it works!


实例

为了更好地理解不同的函数值:这里有五个不同的div元素,用5个不同的值:

#div1 {transition-timing-function: linear;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}
/* Safari */
#div1 {-webkit-transition-timing-function: linear;}
#div2 {-webkit-transition-timing-function: ease;}
#div3 {-webkit-transition-timing-function: ease-in;}
#div4 {-webkit-transition-timing-function: ease-out;}
#div5 {-webkit-transition-timing-function: ease-in-out;}

实例

和上面的例子一样,但指定速度曲线立方贝塞尔曲线函数:

#div1 {transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
/* Safari */
#div1 {-webkit-transition-timing-function: cubic-bezier(0,0,1,1;}
#div2 {-webkit-transition-timing-function: cubic-bezier(0.25,0.1,0.25,1);}
#div3 {-webkit-transition-timing-function: cubic-bezier(0.42,0,1,1);}
#div4 {-webkit-transition-timing-function: cubic-bezier(0,0,0.58,1);}
#div5 {-webkit-transition-timing-function: cubic-bezier(0.42,0,0.58,1);}
