transition-timing-function

定义

transition-timing-function属性指定切换效果的速度。

语法

transition-timing-function: linear|ease|ease-in|ease-out|ease-in-out|cubic-bezier(n,n,n,n);

属性值

说明
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。

上面的效果用cubic-bezier(n,n,n,n)同理可实现:

#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);}
