title: "font-family: monospace, monospace"
body: <p>In <code>normalize.css</code>, the monospace font rules contain</p>
  <pre><code>font-family: monospace, monospace;
  </code></pre>
  <p>Is this different to</p>
  <pre><code>font-family: monospace;
  </code></pre>
  <p>?</p>
  <p>There must be a reason for using that. Maybe it's a workaround for the behaviour of some browsers?</p>
