title: Hiding only text but not iframe in a DIV
body: <p>I'm having difficulty hiding text from a DIV whilst still allowing the iframe within the div to appear. Here is sample code:</p>
  
  <pre><code>&lt;div class="whatever"&gt;
      &lt;iframe src="http://something"&gt;&lt;/iframe&gt;
      Here is some text with &lt;a href="#"&gt;links&lt;/a&gt; and &lt;strong&gt;bold text&lt;/strong&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I need only the <code>&lt;iframe&gt;</code> to appear. Is this easily achievable?</p>
