title: Flask css not updating
body: <p>I am using Flask (the python Package) on my mac, when I first wrote my css it displayed ok. However when I updated it and tried to check it, I only see the first css styles. I have tried restarting the terminal, as well as reinstalling Flask. Any suggestions? Thanks.
  Heres the HTML:</p>
  
  <pre><code>    &lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;Title&lt;/title&gt;   
      &lt;link rel="stylesheet" href="{{ url_for('static', filename='css/style.css') }}"&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
      &lt;header&gt;
          &lt;div class="header"&gt;&lt;/div&gt;
          &lt;div class="logo"&gt;
              &lt;center&gt;&lt;img src="/static/img/p_logo.png" alt="pic"/&gt;&lt;/center&gt;
          &lt;/div&gt;
      &lt;/header&gt; 
  
      &lt;div class="container"&gt;
          {% block content %}
          {% endblock %}
      &lt;/div&gt;
  
  &lt;/body&gt;
  </code></pre>
  
  <p></p>
  
  <p>And heres the CSS:</p>
  
  <pre><code>    * {
  font-family: "Times New Roman", Times, serif;
  }
  
  header {
  background-color: #000000;
  width: 100%;
  height: 7px;
  
  }       
  </code></pre>
