title: Will an iframe render in quirks mode?
body: <p>I'm working on setting up a page and am having difficulty with getting it to look well across browsers (actually just IE, as it renders properly for mozilla and webkit). I'm wanting to rule out quirks mode before seriously considering old IE bugs fixed since IE6. The container page has a declared doctype, however the iframe code does not. Will the iframe content be rendered in quirks-mode (because it does not have a doctype) or standards mode (because the container has a doctype)? The source follows this scheme:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt;
  &lt;html&gt;
  ...
  &lt;body&gt;
  ...
  &lt;iframe ...&gt;
      &lt;html&gt;
      &lt;head&gt;
      ...
      &lt;/head&gt;
      &lt;body&gt;
      ....
      &lt;/body&gt;
      &lt;/html&gt;
  &lt;/iframe&gt;
  ...
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
