<h2>A plain header</h2>

<p>Let's first have a plain header</p>

<h1>An underlined header</h1>

<p>(That's also useful)</p>

<h1>A header with a <a href="http://www.link.com">link</a></h1>

<p>First with a hash</p>

<h2>Another with a <a href="http://www.link.com/">link</a></h2>

<p>This time underlined</p>
