transition-delay

版本： CSS3

CSS的 transition-delay 属性规定了在过渡效果开始作用之前需要等待的时间。值以秒（s）或毫秒（ms）为单位，表明动画过渡效果将在何时开始。取值为正时会延迟一段时间来响应过渡效果；取值为负时会导致过渡立即开始。你可以指定多个延迟时间，每个延迟将会分别作用于你所指定的相符合的css属性（ transition-property ）

示例

/* <time>值 */
transition-delay: 3s;
transition-delay: 2s, 4ms;

/* 全局变量 */
transition-delay: inherit;
transition-delay: initial;
transition-delay: unset;

浏览器支持


IE10以上浏览器都支持 `transition-delay`

语法

transition-delay : <timing-function>

取值：

<timing-function> ：通过 transition-property 中定义被过渡属性，每个 <timing-function> 的值代表与这个属性相对应的timing function.

说明：

检索或设置对象延迟过渡的时间。

如果提供多个属性值，以逗号进行分隔。
对应的脚本特性为 transitionDelay 。

这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

默认值	0s
适用于	所有元素，包含伪对象 `::before` and `::after`
继承性	无
动画性	否
