<title>HTML Example</title>
The indentation tries to be <em>somewhat &quot;do what
I mean&quot;</em>... but might not match your style.
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
<p>The XML mode supports these configuration parameters:</p>
<dt><code>htmlMode (boolean)</code></dt>
<dd>This switches the mode to parse HTML instead of XML. This
means attributes do not have to be quoted, and some elements
(such as <code>br</code>) do not require a closing tag.</dd>
<dt><code>matchClosing (boolean)</code></dt>
<dd>Controls whether the mode checks that close tags match the
corresponding opening tag, and highlights mismatches as errors.
<dt><code>alignCDATA (boolean)</code></dt>
<dd>Setting this to true will force the opening tag of CDATA
blocks to not be indented.</dd>
