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，通过多个div容器来分别显示猫不同的身体部位，代码如下：

<div class="all-wrap">
  <div class="all">
    <div class="yarn"></div>
    <div class="cat-wrap">
      <div class="cat">
        <div class="cat-upper">
          <div class="cat-leg"></div>
          <div class="cat-leg"></div>
          <div class="cat-head">
            <div class="cat-ears">
              <div class="cat-ear"></div>
