/**
 *
 * Simple CSS for a better default style.
 * Example page (everything is optional):
 *
 * 	<header>
 * 		<h1>My HEADER</h1>
 * 		<nav>
 * 			<a href=".">Link 1</a>
 * 			<a href=".">Link 2</a>
 * 			<a href=".">Link 3</a>
 * 		</nav>
 * 	</header>
 * 	<article>
 * 		<h1>Main title</h1>
 * 		Some <strong>demo</strong> text...
 * 		<pre><code>
 * 			bash$ _
 * 		</code></pre>
 * 	</article>
 *
 * Note: <header>, <nav> and <article> can be replaced with classes, too.
