CSS animation-timing-function 属性


示例

以相同的速度从开始到结束播放动画

div {
  animation-timing-function: linear;
}
试试看 »

下面有更多“试试看”示例。


定义和用法

The animation-timing-function 指定动画的速度曲线。

速度曲线定义了动画从一组 CSS 样式更改为另一组 CSS 样式所用的时间。

速度曲线用于使更改平滑。

默认值 ease
继承
可动画 否。 阅读有关可动画
版本 CSS3
JavaScript 语法 object.style.animationTimingFunction="linear" 试试看

浏览器支持

表中的数字指定完全支持该属性的第一个浏览器版本。

属性
animation-timing-function 43 10 16 9 30


CSS 语法

animation-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;

animation-timing-function 使用一个称为三次贝塞尔曲线 (Cubic Bezier curve) 的数学函数来创建速度曲线。您可以在此函数中使用自己的值,也可以使用预定义的值之一。

属性值

描述 演示
linear 动画从开始到结束的速度相同 播放 »
ease 默认值。动画开始缓慢,然后变快,然后慢慢结束 播放 »
ease-in 动画开始缓慢 播放 »
ease-out 动画结束缓慢 播放 »
ease-in-out 动画开始和结束都很缓慢 播放 »
step-start 等同于 steps(1, start)
step-end 等同于 steps(1, end)
steps(int,start|end) 指定一个步进函数,有两个参数。第一个参数指定函数中的间隔数。它必须是一个正整数(大于 0)。第二个参数是可选的,可以是“start”或“end”值,指定值在间隔内发生变化的点。如果省略第二个参数,则它将被赋予“end”值。
cubic-bezier(n,n,n,n) 在三次贝塞尔函数中定义您自己的值
可能的值是 0 到 1 之间的数字值
initial 将此属性设置为其默认值。 阅读有关initial
inherit 从其父元素继承此属性。 阅读有关inherit

提示: 在下面的“更多示例”部分中尝试不同的值。


更多示例

示例

为了更好地理解不同的时间函数值;
这里有五个具有五个不同值的 <div> 元素

#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;}
试试看 »

示例

与上面的示例相同,但速度曲线是用三次贝塞尔函数定义的

#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);}
