CSS transition-timing-function 属性


实例

以相同的速度从开始到结束的过渡效果:

div {
  transition-timing-function: linear;
}
亲自试一试 »

定义和用法

transition-timing-function 属性规定过渡效果的速度曲线。

该属性允许过渡效果随着时间来改变其速度。

默认值: ease
继承性: no
支持动画: no. 阅读有关动画的信息
版本: CSS3
JavaScript 语法: object.style.transitionTimingFunction="linear" 测试一下

浏览器支持

表中的数字表示支持该属性的第一个浏览器版本。

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

语法

transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|step-start|step-end|steps(int,start|end)|cubic-bezier(n,n,n,n)|initial|inherit;

属性值

描述
ease 默认值,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))。
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-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))。
step-start 相当于 steps(1, start)
step-end 相当于 steps(1, end)
steps(int,start|end) 指定带有两个参数的步进函数。第一个参数指定函数中的间隔数。它必须是正整数(大于0)。第二个参数(可选)是值 "start" 或 "end",并指定在间隔内发生值更改的点。如果省略了第二个参数,则该参数的值为 "end"
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。
initial 将此属性设置为其默认值。请参阅 initial
inherit 从其父元素继承此属性。请参阅 inherit

提示: 请在以下实例中测试不同的值,这样可以更好地理解它们的工作原理!

实例

为了更好地理解不同的函数值,请看下面带有五个不同值的五个不同的 div 元素:

#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;}
亲自试一试 »

实例

与上例相同,但通过 cubic-bezier 来规定速度曲线:

#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);}
