title: Can I use two col-md-6 inside a col-md-8?
body: <p>Can I use two col-md-6 inside a col-md-8 or must I use two col-md-4?</p>
  
  <pre><code>&lt;div class="row"&gt;
   &lt;div class="col-md-8"&gt;
      &lt;div class="row"&gt;   
          &lt;div class="col-md-6"&gt;
          &lt;/div&gt; 
          &lt;div class="col-md-6"&gt;
          &lt;/div&gt; 
      &lt;/div&gt;
  
   &lt;/div&gt;
  
   &lt;div class="col-md-4"&gt;
   &lt;/div&gt; 
  &lt;/div&gt;
  </code></pre>
  
  <p>Can I consider a col-md-8 as a col-md-12 if I insert a <code>&lt;div class="row"&gt;</code> inside the col-md-8?</p>
  
  <p>I tried it and it offers me the required result, but <strong>is it proper</strong>? </p>
