Can a GitHub wiki embed HTML
<p>I would like to create a wiki page that is a preamble (standard markdown) followed by an HTML/JS code listing followed by (in a frame I suppose) the page that this code would generate.</p>

<p>Is this possible?</p>

<p>PS The code is: <a href="http://pipad.org/MathBox/slides_simple.html" rel="noreferrer">http://pipad.org/MathBox/slides_simple.html</a></p>
