CSS3動畫循環次數
CSS3的animation-iteration-count屬性詳解:
此屬性用於設定animation動畫的過渡時長。
更多關於animation屬性內容可以參考CSS3的animation屬性用法詳解一章節。
語法結構:
animation-iteration-count：infinite | <number> [ , infinite | <number> ]*
參數解析:
1.infinite:規定動畫可以無限迴圈。
2.number:明確指定動畫循環的次數。
特別說明:
如果提供多個屬性值，以逗號進行分隔。
對應的腳本特性為animationIterationCount。
程式碼實例:
實例一:
<!DOCTYPE html>
<html>
<head>
<meta charset=" utf-8">
<meta name="author" content="//m.sbmmt.com/" />
<title>php中文网</title>
<style type="text/css">
div{
width:100px;
height:100px;
background:red;
position:relative;
animation:theanimation infinite alternate;
-webkit-animation:theanimation alternate ;
-moz-animation:theanimation alternate ;
-o-animation:theanimation alternate ;
-ms-animation:theanimation alternate ;
-webkit-animation-duration:8s;
-moz-animation-duration:8s;
-o-animation-duration:8s;
-ms-animation-duration:8s;
animation-duration:8s;
-webkit-animation-iteration-count:infinite;
-moz-animation-iteration-count:infinite;
-o-animation-iteration-count:infinite;
-ms-animation-iteration-count:infinite;
animation-iteration-count:infinite;
}
@keyframes theanimation{
0%{top:0px;left:0px;background:red;}
25%{top:0px;left:100px;background:blue;}
50%{top:100px;left:100px;background:yellow;}
75%{top:100px;left:0px;background:green;}
100%{top:0px;left:0px;background:red;}
}
@-moz-keyframes theanimation{
0% {top:0px;left:0px;background:red;}
25%{top:0px;left:100px;background:blue;}
50%{top:100px;left:100px;background:yellow;}
75%{top:100px;left:0px;background:green;}
100%{top:0px;left:0px;background:red;}
}
@-webkit-keyframes theanimation{
0%{top:0px;left:0px;background:red;}
25%{top:0px;left:100px;background:blue;}
50%{top:100px;left:100px;background:yellow;}
75%{top:100px;left:0px;background:green;}
100%{top:0px;left:0px;background:red;}
}
@-o-keyframes theanimation{
0%{top:0px;left:0px;background:red;}
25%{top:0px;left:100px;background:blue;}
50%{top:100px;left:100px;background:yellow;}
75%{top:100px;left:0px;background:green;}
100%{top:0px;left:0px;background:red;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>以上程式碼設定動畫可以無限循環。
實例二:
<!DOCTYPE html>
<html>
<head>
<meta charset=" utf-8">
<meta name="author" content="http://www.softwhy.com/" />
<title>蚂蚁部落</title>
<style type="text/css">
div{
width:100px;
height:100px;
background:red;
position:relative;
animation:firstanimation 5s alternate,secondanimation 2s alternate;
-webkit-animation:firstanimation 5s alternate,secondanimation 2s alternate;
-moz-animation:firstanimation 5s alternate,secondanimation 2s alternate;
-o-animation:firstanimation 5s alternate,secondanimation 2s alternate;
-ms-animation:firstanimation 5s alternate,secondanimation 2s alternate;

-moz-animation-iteration-count:infinite,2;
-o-animation-iteration-count:infinite,2;
-ms-animation-iteration-count:infinite,2;
animation-iteration-count:infinite,2;
}
@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>上面程式碼使用animation-iteration-count屬性規定了兩個參數，也就是兩個動畫的執行次數。
