transition-timing-function

transition-timing-function用来定义过渡动画的效果。

语法

transition-timing-function: linear | ease | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>)[ ,linear | ease | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>) ]* ;设置动画执行的方式(缓动效果)。
语法项目 说明
初始值 ease
适用于 所有元素
可否继承
媒介 视觉
版本 CSS3.0

说明

transition-timing-function可以设置动画的过渡效果,默认值ease。

取值

ease:缓解效果,等同于cubic-bezier(0.25,0.1,0.25,1.0)函数,既立方贝塞尔。

linear:线性效果,等同于cubic-bezier(0.0,0.0,1.0,1.0)函数。

ease-in:渐显效果,等同于cubic-bezier(0.42,0,1.0,1.0)函数。

ease-out:渐隐效果,等同于cubic-bezier(0,0,0.58,1.0)函数。

ease-in-out:渐显渐隐效果,等同于cubic-bezier(0.42,0,0.58,1.0)函数。

cubic-bezier:特殊的立方贝塞尔曲线效果。
