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)。

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。
实例代码
CSS
.demo_box{ -webkit-transition:all 2s 0.5s; -moz-transition:all 2s 0.5s; position:relative; left:10px; width:50px; height:50px; border-radius:50px; margin:10px 0; overflow:hidden; } .ease{ -webkit-transition-timing-function:ease; -moz-transition-timing-function:ease; } .linear{ -webkit-transition-timing-function:linear; -moz-transition-timing-function:linear; } .ease-in{ -webkit-transition-timing-function:ease-in; -moz-transition-timing-function:ease-in; } .ease-out{ -webkit-transition-timing-function:ease-out; -moz-transition-timing-function:ease-out; } .ease-in-out{ -webkit-transition-timing-function:ease-in-out; -moz-transition-timing-function:ease-in-out; } .cubic-bezier{ -webkit-transition-timing-function:cubic-bezier(0.52,0,0.58,1.0); -moz-transition-timing-function:cubic-bezier(0.52,0,0.58,1.0); } .run{ left:500px; }
