title: Bootstrap: Multiple nested rows within row?
body: <p>I know you can nest rows within nested columns, but is it 'against the rules' to nest rows directly within rows?</p>
  
  <p>eg:</p>
  
  <pre><code>&lt;div class="row"&gt;
  
    &lt;div class="row"&gt;
       cols in here
    &lt;/div&gt;
  
    &lt;div class="row"&gt;
       cols in here
    &lt;/div&gt;
  
    &lt;div class="row"&gt;
       cols in here
    &lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>Or must these always be within columns?</p>
