title: CSS - Font for a web based editor
body: <p>I'm building a web based code editor. I'm currently using </p>
  
  <pre><code>font-family : "Courier New", Courier, monospace
  </code></pre>
  
  <p>as the rule for both line numbers and the source code. </p>
  
  <ul>
  <li>Does it work on every OS?</li>
  <li>Is there a better font than Courier new that's both targeted towards source code and installed in majority of computers?</li>
  </ul>
