title: CSS not working in HTML file
body: <p>It has been working... But I don't know why it is not working anymore. I am using Django to set up a local server (?) and I use MySQL for something else. The .css file is into a folder where the .html file is located, and like I said before it has been working.</p>
  
  <p>My code inside the <strong>head</strong>:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  
  &lt;html lang="en"&gt;
  
  {% load static %}
  
  &lt;head&gt;
      &lt;meta charset="utf-8" /&gt;
      &lt;title&gt;JFP&lt;/title&gt;
      &lt;link rel="stylesheet" href="http://s3.amazonaws.com/codecademy-content/courses/ltp/css/bootstrap.css"&gt;
          &lt;link rel="stylesheet" href="main.css" &gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  
  &lt;div class="header"&gt; 
  ...
  </code></pre>
  
  <p>My <strong>.css</strong> is not worth mentioning, is it?</p>
