title: Copy the content of a div into another div
body: <p>I have two divs on my website. They both share the same css properties, but one of them holds 24 other divs. I want all of these 24 divs to be copied into the other div.
  This is how it looks like:</p>
  
  <pre><code>&lt;div id="mydiv1"&gt;
      &lt;div id="div1"&gt;
      &lt;/div&gt;
      &lt;/div id="div2&gt;
      &lt;/div&gt;
      //and all the way up to div 24.
  &lt;/div&gt;
  
  &lt;div id="mydiv2"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want all of the 24 divs within mydiv1 to be copied into mydiv2 when the page loads.</p>
  
  <p>Thanks in advance</p>
