CSS3 transition-timing-function 属性
过渡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 */
-webkit-transition-timing-function: linear; /* Safari and Chrome */
浏览器支持
表格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。
| 属性 | |||||
|---|---|---|---|---|---|
| transition-timing-function | 26.0 4.0 -webkit- |
10.0 | 16.0 4.0 -moz- |
6.1 3.1 -webkit- |
12.1 10.5 -o- |
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);
| 值 | 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!
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;}
#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;}
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);}
#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);}
