"font-family: monospace, monospace" : <p>I'm just curious, in <code>normalize.css</code>, the monospace font rules contain</p>

<pre><code>font-family: monospace, monospace;
</code></pre>

<p>Is there a difference to</p>

<pre><code>font-family: monospace;
</code></pre>

<p>? There must be a reason for using that. Maybe it's a workaround for the behaviour of some browsers?</p>
