transition-delay - 过渡效果开始作用之前需要等待的时间 - css 过度
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
/* 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:取值:
- :通过
transition-property
中定义被过渡属性,每个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。
