title: Getting divs with same class name in a div
body: <p>Lets say we have this code:</p>
  
  <pre><code>&lt;div id='m1'&gt;
  
  &lt;div class="c"&gt;&lt;/div&gt;
  &lt;div class="c"&gt;&lt;/div&gt;
  &lt;div class="c"&gt;&lt;/div&gt;
  
  &lt;/div&gt;
  &lt;div id='m2'&gt;
  
  &lt;div class="c"&gt;&lt;/div&gt;
  &lt;div class="c"&gt;&lt;/div&gt;
  &lt;div class="c"&gt;&lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
