Margin collapse : <p>How can I disable margin collapse and get 200px margin without changing the HTML?</p>

<p>code: </p>

<pre><code>&lt;style&gt;

div{
  font-size: 100px;
  border: 10px solid black;
  padding: 20px;
  margin: 100px;

&lt;/style&gt;

&lt;body&gt;

  &lt;div&gt;AAAA&lt;/div&gt;

  &lt;div&gt;AAAA&lt;/div&gt;

&lt;/body&gt;
</code></pre>

<p>Thanks, :D.</p>
