过渡时间 | transition-duration
过渡时期
transition-duration
属性以秒或毫秒为单位指定过渡动画所需的时间。默认值为 0s ,表示不出现过渡动画。
可以指定多个时长,每个时长会被应用到由 transition-property
指定的对应属性上。如果指定的时长个数小于属性个数,那么时长列表会重复。如果时长列表更长,那么该列表会被裁减。两种情况下,属性列表都保持不变。
/* <time> values */
transition-duration: 6s;
transition-duration: 120ms;
transition-duration: 1s, 15s;
transition-duration: 10s, 30s, 230ms;
/* Global values */
transition-duration: inherit;
transition-duration: initial;
transition-duration: unset;
初始值 | 0s |
---|---|
适用元素 | all elements, ::before and ::after pseudo-elements |
是否是继承属性 | no |
适用媒体 | interactive |
计算值 | as specified |
Animation type | discrete |
正规顺序 | the unique non-ambiguous order defined by the formal grammar |
语法
值
<time><time>类型。表示过渡属性从旧的值转变到新的值所需要的时间。如果时长是 0s ,表示不会呈现过渡动画,属性会瞬间完成转变。不接受负值。
