弄清 CSS3 的 transition 和 animation
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);

.accordion a{
display: block;
padding:5px 10px;
background-color:#ccc;
color:#000;
/*可以去掉链接的下划线等修饰效果*/
text-decoration:none;
}
.accordion a:hover{
background-color:#999;

.accordion div{
background-color:#cda;
color:#222;

}
#accordion div{
/*先隐藏起来*/
height:0;
overflow:hidden;
-webkit-transition:height 600ms ease;
}
#accordion div:target{
height:110px;
}
animation
animation 属性是如下这些属性的简写
animation-name: none
animation-duration: 0s
animation-timing-function: ease
animation-delay: 0s
animation-iteration-count: 1
animation-direction: normal
animation-fill-mode: none
用法
animation:
animation-name
time(duration)
timing-function
time(delay)
animation-iteration-count( 结束之前的循环次数)
single-animation-direction
/*{
animation-direction: normal (每次从正方向开始)
animation-direction: reverse （每次从反方向开始）
animation-direction: alternate （正反往复）
}*/
single-animation-fill-mode
