title: Negative Margin in Firefox Using Bootstrap
body: <p>I am using Twitter Bootstrap plugin, mainly just the grid system currently.</p>
  
  <p>I am trying to put one row on top of another doing some stuff for responsive design. </p>
  
  <p>In Chrome this works perfectly:</p>
  
  <pre><code>&lt;div class="container"&gt;
      &lt;div class="row"&gt;
          &lt;div class="content"&gt;
              abcd
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="row" id="moveUpRow"&gt;
          &lt;div class="content"&gt;
              efgh
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>CSS:</p>
  
  <pre><code>.row {
      height: 200px;
  }
  
  #moveUpRow {
      margin-top: -200px;
  }
  </code></pre>
  
  <p>But in Firefox and IE they both ignore the negative margin. I have tried <code>top: -200px</code>, but that just moves up the <code>row</code> and not all of the elements below the row. Leaving big white space.</p>
  
  <p>Any other solutions to this problem? Or any suggestions on how to "pull" up any content below the row?</p>
