CSS3的transition和animation的用法实例介绍
摘要:transitiontransition属性是transition-property,transition-duration,transit...

transition

transition 属性是

transition-property,

transition-duration,

transition-timing-function,

transition-delay

的简称,用于设定一个元素的两个状态,不同的状态可以用伪类,比如:hover, :active 或者是通过 javascript 动态设定。IE10+支持。

所以 transition 的初始值为:

transition-delay: 0s;

transition-duration: 0s;

transition-property: all;

transition-timing-function: ease;

用法

div {

transition: <property> <duration> <timing-function> <delay>;

}

并且有事件可以监测 transition 结束

el.addEventListener("transitionend",updateTransition,true);

//in webkit

el.addEventListener("webkitTransitionEnd",updateTransition,true);
