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);

}
#fade {
/*opacity:1;
-webkit-transition: opacity 10s liner 10s;*/
position: relative;
transition-property: font-size;
transition-duration: 0.5s;
transition-delay: 0;
font-size: 14px;
}
#fade:hover {
font-size: 36px;
}

/* demo2 */
#nudge{
-webkit-transition-property: color,
background-color,padding-left;
-webkit-transition-duration: 500ms,500ms, 500ms;
}
#nudge:hover{
background-color: #efefef;
color: #333;
padding-left: 50px;
}
#bounce:hover {
-webkit-animation-name:bounce;
-webkit-animation-duration:1s;
-webkit-animation-iteration-count:2;
-webkit-animation-direction:alternate
}
@-webkit-keyframes bounce {
from{margin-left:0;}
to{margin-left:250px;}
}
#spin{
-webkit-transition: -webkit-transform 10s ease-in;
}
#spin:hover{
-webkit-transform: rotate(36000deg);
}
.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;

}
.accordion div p{

}
#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
