title: Bootstrap row with empty col-md
body: <p>I have simple div with row class having child div with col-md-3 class.</p>
  
  <pre><code>&lt;div class="row"&gt;
      &lt;div class="col-md-3"&gt;
      &lt;/div&gt;
      &lt;div class="col-md-3"&gt;
      &lt;/div&gt;
      &lt;div class="col-md-3"&gt;
      &lt;/div&gt;
      &lt;div class="col-md-3"&gt;
      &lt;/div&gt;
      &lt;div class="col-md-3"&gt;
      &lt;/div&gt;
      &lt;div class="col-md-3"&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I am getting for divs in first row, but my second row has space and then the remaining divs.</p>
  
  <pre><code>DIV1        DIV2         DIV3        DIV4
              DIV5         DIV6        DIV7
  </code></pre>
  
  <p>I am guessing the issue to be with "DIV4", but not able to get the cause and fix for it.</p>
