实例二:
<!DOCTYPE html>
<html>
<head>
<meta charset=" utf-8">
<meta name="author" content="http://www.php.cn/" />
<title>php中文网</title>
<style type="text/css">
div{
width:100px;
height:100px;
background:red;
position:relative;
animation:firstanimation infinite alternate,secondanimation infinite alternate;
-webkit-animation:firstanimation infinite alternate,secondanimation infinite alternate;
-moz-animation:firstanimation infinite alternate,secondanimation infinite alternate;
-o-animation:firstanimation infinite alternate,secondanimation infinite alternate;
-ms-animation:firstanimation infinite alternate,secondanimation infinite alternate;
-webkit-animation-duration:5s,2s;
-moz-animation-duration:5s,2s;
-o-animation-duration:5s,2s;
-ms-animation-duration:5s,2s;
animation-duration:5s,2s;
}
@keyframes firstanimation{
0% {left:0px;}
100% {left:200px;}
}
@-webkit-keyframes firstanimation{
0% {left:0px;}
100% {left:200px;}
}
@-moz-keyframes firstanimation{
0% {left:0px;}
100% {left:200px;}
}
@-o-keyframes firstanimation{
0% {left:0px;}
100% {left:200px;}
}
@-ms-keyframes firstanimation{
0% {left:0px;}
100% {left:200px;}
}
@keyframes secondanimation{
0% {top:0px;}
100% {top:200px;}
}
@-webkit-keyframes secondanimation{
0% {top:0px;}
100% {top:200px;}
}
@-moz-keyframes secondanimation{
0% {top:0px;}
100% {top:200px;}
}
@-o-keyframes secondanimation{
0% {top:0px;}
100% {top:200px;}
}
@-ms-keyframes secondanimation{
0% {top:0px;}
100% {top:200px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>以上代码使用animation-duration规定了两个动画时长分别用于两个动画。
