<h2 id="概要">概要</h2>

<p>CSS的<strong>transition-delay</strong>属性规定了在<a href="/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions">过渡效果</a>开始作用之前需要等待的时间。</p>

<p>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。</p>

<p>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（<strong>transition-property</strong>）</p>
