页面的head部分，需引入页面的样式文件，代码如下：

<link type="text/css" rel="stylesheet" href="css/style.css">

页面的body部分，需设置好每个长方体对应的容器，代码如下：

<div class="stage">
  <div class="boxes">
    <div class="box">
      <div class="box-wrapper">
        <div class="front"></div>
        <div class="back"></div>
        <div class="top"></div>
        <div class="bottom"></div>
        <div class="left"></div>
        <div class="right"></div>
      </div>
    </div>
    <div class="box">
      <div class="box-wrapper">
        <div class="front"></div>
        <div class="back"></div>
        <div class="top"></div>
