概要

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

初始值0s
适用元素all elements, ::before and ::after pseudo-elements
是否是继承属性
适用媒体interactive
计算值as specified
Animation typediscrete
正规顺序the unique non-ambiguous order defined by the formal grammar

语法

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

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

取值

<time>
表明动画效果属性生效之前需要等待的时间。

语法形式

<time>#
