title: How to do auto-width with HTML IFrame
body: <p>I am trying to use iframe to open other URLs. But for reason the width iframe is fixed in 155px.</p>
  
  <p>I need to resize the width iframe to fit the whole SRC iframe.</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
      &lt;body&gt;
          &lt;iframe frameborder="0" scrolling="no" height="100%" width="100%" src="http://www.gnu.org/"&gt;&lt;/iframe&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I tried width="100%", but didn't work.</p>
