CSS 3 transition-timing-function

css 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* );

值说明

值	描述
linear	规定以相同速度开始至结束的过渡效果等同于 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等同于 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同于 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

浏览器支持

下表中的数字表示支持该属性的第一个浏览器版本号。

紧跟在 -webkit-, -ms- 或 -moz- 前的数字为支持该前缀属性的第一个浏览器版本号。

Chrome	IE	Firefox	Safari	Opera
26.0 4.0 -webkit-	10.0	16.0 4.0 -moz-	6.1 3.1 -webkit-	12.1 10.5 -o-

范例

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 */

范例 2

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;}

范例 3

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);}
