title: Div and table not working properly in Firefox
body: <p>I am making a microsite via Dreamweaver using the fluid layout. In it, I had my header and banner inside a table under a div like so:</p>
  
  <pre><code>&lt;div id="divHeader"&gt;
  &lt;table cellpadding="0" cellspacing="0" border="0" width="100%"&gt;
      &lt;tbody&gt;
          &lt;tr&gt;
              &lt;td style="width: 30px;"&gt;&lt;/td&gt;
              &lt;td style="vertical-align: middle; font-size: 1.3rem; font-weight: bold;"&gt;
                  &lt;p&gt;&lt;span&gt;Move Toward &lt;/span&gt; &lt;span class="hdr"&gt;Zero Unplanned Downtime&lt;/span&gt;&lt;/p&gt;
              &lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td colspan="2" style="text-align: center;"&gt;
                      &lt;img src="images/Mining_site_1192x181-12.png" alt=""/&gt;
              &lt;/td&gt;
          &lt;/tr&gt;
      &lt;/tbody&gt;
    &lt;/table&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>In most browsers, this works well (including mobile browsers):</p>
  
  <p><img src="https://i.stack.imgur.com/6PGZg.png" alt="banner in Chrome"></p>
  
  <p>Unfortunately, in Firefox, it's shown this way:</p>
  
  <p><img src="https://i.stack.imgur.com/GRHAm.png" alt="banner in Firefox"></p>
  
  <p>When I used the built-in Inspect Elemet, this is what I see in Firefox:</p>
  
  <p><img src="https://i.stack.imgur.com/QXqXq.png" alt="Firefox Inspect Element"></p>
  
  <p>For some reason, the table is displayed outside the DIV element. The table doesn't have a CSS class associated with it, and as for the DID, this is the CSS for its class divHeader:</p>
  
  <pre><code>#divHeader {
      font-family: Arial;
      background-color: #F89329;
      text-transform: uppercase;
      font-size: 1rem;
      color: #fff;
      line-height: 1rem;
      border: none;
  }
  </code></pre>
  
  <p>Is there an issue with tables within div in Firefox? If so, what's a good workaround?</p>
  
  <p>Here is my CSS code:</p>
  
  <pre class="lang-css prettyprint-override"><code>@charset "utf-8";

  */

      max-width: 100%;
  }

      text-decoration: none;
  }

      color: #F59D51;
      text-decoration: none;
  }
  
  /* IE 6 does not support max-width so default to width 100% */
  .ie6 img {
      width:100%;
  }
