6. 属性简写
与上面的动画相同，但是使用了简写的动画 animation 属性：
实例：demo04
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
p{
width:100px;
height:100px;
background:red;
position:relative;
animation:myfirst 5s linear 2s infinite alternate;
-moz-animation:myfirst 5s linear 2s infinite alternate;
-webkit-animation:myfirst 5s linear 2s infinite alternate;
-o-animation:myfirst 5s linear 2s infinite alternate;
}
@keyframes myfirst {
0% {background:red; left:0px; top:0px;}
25% {background:yellow; left:200px; top:0px;}
50% {background:blue; left:200px; top:200px;}
75% {background:green; left:0px; top:200px;}
100% {background:red; left:0px; top:0px;}
}
@-moz-keyframes myfirst {
0% {background:red; left:0px; top:0px;}
25% {background:yellow; left:200px; top:0px;}
50% {background:blue; left:200px; top:200px;}
75% {background:green; left:0px; top:200px;}
100% {background:red; left:0px; top:0px;}
}
@-webkit-keyframes myfirst {
0% {background:red; left:0px; top:0px;}
25% {background:yellow; left:200px; top:0px;}
50% {background:blue; left:200px; top:200px;}
75% {background:green; left:0px; top:200px;}
100% {background:red; left:0px; top:0px;}
}
@-o-keyframes myfirst {
0% {background:red; left:0px; top:0px;}
25% {background:yellow; left:200px; top:0px;}
50% {background:blue; left:200px; top:200px;}
75% {background:green; left:0px; top:200px;}
100% {background:red; left:0px; top:0px;}
}
</style>
</head>
<body>
<p></p>

7. Animate.css插件
Animate.css是某位大牛写好的动画效果集合，需要的时候可以直接下载导入到项目中，在需要的元素上添加相关的类即可使用相对应的动画效果。
Animate.css:源码版下载
Animate.min.css压缩版下载
如：
<p id="test"class="animated infinite bounce ">bounce</p>
Animated：表示使用Animate.css的动画
Infinite：表示动画效果无限循环
Bounce：是动画效果
动画效果有很多，下面的案例就展示了各种动画效果
实例：demo05
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" type="text/css" href="css/animate.min.css" />
<style type="text/css">
#content{
padding-top: 20%;
}
#test {
width: 50%;
line-height: 100px;
margin: auto;
background-color: rgba(10, 10, 10, 0.2);
text-align: center;
}
select{
display: block;
height: 45px;
margin: auto;
}
</style>
<script type="text/javascript">
window.onload = function(){
document.getElementById('select').onchange = function(){
val = this.options[this.selectedIndex].value;
document.getElementById('test').setAttribute('class','animated infinite '+val);
}
}

8. Wow.js插件
Wow.js是javascript动画插件，经常配合animate.css一起使用。动画效果会在元素第一次出现在页面中时起作用。
wow.js:源码版下载
wow.min.js压缩版下载
Wow.js的使用方法
引入wow.js
在需要使用的元素上添加class=”wow”
使用js初始化
实例：demo06
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" type="text/css" href="css/animate.min.css" />
<script src="js/wow.min.js" type="text/javascript" charset="utf-8"></script>
<style type="text/css">
#content {
padding-top: 20%;
}
#test {
width: 50%;
line-height: 100px;
margin: auto;
background-color: rgba(10, 10, 10, 0.2);
text-align: center;
}
</style>
<script type="text/javascript">
var wow = new WOW({
boxClass: 'wow', // 动画使用的class
animateClass: 'animated infinite', // 附加的class
offset: 0, // 当元素进入页面多少位置的时候开始动画，默认0
mobile: true, // 是否在移动设备上显示动画效果，默认true
live: true, // 是否异步加载内容，默认true
callback: function(box) {},
scrollContainer: null
});
wow.init();
</script>
</head>
<body>
<p id="content">
<p id="test" class="wow bounce">bounce</p>
</p>
</body>
</html>
