文字

语法：

transition-timing-function：<single-transition-timing-function>[,<single-transition-timing-function>]*

<single-transition-timing-function> = ease | linear | ease-in | ease-out | ease-in-out | step-start | step-end | steps(<integer>[, [ start | end ] ]?) | cubic-bezier(<number>, <number>, <number>, <number>)

默认值：ease

适用于：所有元素，包含伪对象:after和:before

继承性：无

动画性：否

计算值：指定值

媒体：交互

取值：

  • linear：线性过渡。等同于贝塞尔曲线(0.0, 0.0, 1.0, 1.0)

  • ease：平滑过渡。等同于贝塞尔曲线(0.25, 0.1, 0.25, 1.0)

  • ease-in：由慢到快。等同于贝塞尔曲线(0.42, 0, 1.0, 1.0)

  • ease-out：由快到慢。等同于贝塞尔曲线(0, 0, 0.58, 1.0)

  • ease-in-out：由慢到快再到慢。等同于贝塞尔曲线(0.42, 0, 0.58, 1.0)

  • step-start：等同于 steps(1, start)

  • step-end：等同于 steps(1, end)

  • steps(<integer>[, [ start | end ] ]?)：接受两个参数的步进函数。第一个参数必须为正整数，指定函数的步数。第二个参数取值可以是start或end，指定每一步的值发生变化的时间点。第二个参数是可选的，默认值为end。

  • cubic-bezier(<number>, <number>, <number>, <number>)：特定的贝塞尔曲线类型，4个数值需在[0, 1]区间内

说明：

检索或设置对象中过渡的动画类型。

  • 如果提供多个属性值，以逗号进行分隔。

  • 对应的脚本特性为transitionTimingFunction。
