如何使用Pure CSS？

问题描述 投票：2回答：2

我想使用此处提供的代码创建404错误网页：

https://codepen.io/SofiaSergio/pen/RMjyRL

正如作者提到的，这是纯CSS。但是我不确定Pure CSS的用法是否与标准CSS相同。我创建了一个HTML和CSS文件mystyle.css，并将它们放在文件夹中

<html>
<head>
<link rel="stylesheet" type="text/css" href="mystyle.css" />
</head>

<body>       
<div class="text"><p>503</p></div>
<div class="container">
  <!-- caveman left -->
  <div class="caveman">
    <div class="leg">
      <div class="foot"><div class="fingers"></div></div>      
    </div>
    <div class="leg">
      <div class="foot"><div class="fingers"></div></div>      
    </div>
    <div class="shape">
      <div class="circle"></div>
      <div class="circle"></div>
    </div>
    <div class="head">
      <div class="eye"><div class="nose"></div></div>
      <div class="mouth"></div>
    </div>
    <div class="arm-right"><div class="club"></div></div>    
  </div>
  <!-- caveman right -->
  <div class="caveman">
    <div class="leg">
      <div class="foot"><div class="fingers"></div></div>      
    </div>
    <div class="leg">
      <div class="foot"><div class="fingers"></div></div>      
    </div>
    <div class="shape">
      <div class="circle"></div>
      <div class="circle"></div>
    </div>
    <div class="head">
      <div class="eye"><div class="nose"></div></div>
      <div class="mouth"></div>
    </div>
    <div class="arm-right"><div class="club"></div></div>    
  </div>
</div>

 </html>

但是，它只显示了大量橙色背景。我试图用样式标签制作CSS，但结果却相同：

<html>
<head>
<style>
<link rel="stylesheet" type="text/css" href="mystyle.css" />
 body { background-color: #FF7F2E; font-family: 'Concert One', cursive; margin: 0; overflow: hidden; padding: 0; }

我实际上要做的是将代码添加到wordpress页面。我通常创建一个HTML代码块，然后将CSS粘贴到主题的“自定义CSS”部分中。但是，以上代码在wordpress中均无效。如果有人给我一个使代码可行的线索，我将不胜感激。谢谢
