<p>By setting an editor's <code>height</code> style
to <code>auto</code> and giving
the <a href="../html/manual.html#option_viewportMargin"><code>viewportMargin</code></a>
a value of <code>Infinity</code>, CodeMirror can be made to
automatically resize to fit its content.</p>

    <script>
      var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
        lineNumbers: true,
        viewportMargin: Infinity
      });
    </script>
