本文实例为大家分享了JavaScript实现抖音罗盘时钟的具体代码，供大家参考，具体内容如下
其实很早以前就想发了，很多东西其实并不难，只要多动手动脑就行了，下面直接上代码，其他的自己下去慢慢研究吧！
HTML部分代码：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>js仿抖罗盘时钟</title> <link rel="stylesheet" href="css/demo.css" > </head> <body> <div ></div> <script src="js/demo.js"></script> </body> </html>
css部分代码：
*{
margin:0;
padding:0
}
html,body{
width:100%;
height:100%;
background-color:#000;
overflow:hidden
}
#clock{
position:relative;
width:100%;
height:100%;
background:#000
}
.label{
display:inline-block;
color:#4d4d4d;
text-align:center;
padding:0 5px;
font-size:19px;
transition:left 1s,top 1s;
transform-origin:0% 0%
}
