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);

实例

HTML

<!--  DEMO 1: Fade Block -->
<div id="fade">move here  !
</div><div id="nudge">mouse on me 
</div><div id="bounce">Place mouse on  me i will bounce!</div><div id="spin">Place mouse on  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i won  me i will spin</div><div id="accordion" class="accordion"><a href="#first">This is first tab</a><div id="first"><p>Lorem ipsum </p> </div><a href="#second">This is second tab</a><div id="second"><p>Lorem ipsum </p> </div><a href="#third">This is third tab</a><div id="third"><p>Lorem ipsum </p> </div>
</div>

}#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;color:#222;
}
.accordion div p{padding:20px
}#accordion div{/*先隐藏起来*/height:0;overflow:hidden;-webkit-transition:height 600ms ease;
}#accordion div:target{height:110px;
}

animation

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-nametime(duration)timing-functiontime(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
