CSS动画

利用CSS内的animation: 秒数 infinite name(与@keyframes属性的name相同），以及 transform: rotate3d（x,y,z,角度deg）进行简单的动画

 1 <!DOCTYPE html>
 2 <html>
 3     <head>
 4         <meta charset="utf-8">
 5         <title></title>
 6         <link rel="stylesheet" type="text/css" href="../Css/register.css"/>
 7     </head>
 8     
 9     <body style="margin: 0;padding: 0;">
10         <div id="trans-test">
11             <div class="groundone">
12                 
13             </div>
14             <div class="groundtwo">
15                 
16             </div>
17             <div class="groundthr">
18                 
19             </div>
20         </div>
21     </body>
22 </html>

以下是CSS代码
