    <h1>CodeMirror: Closebrackets Demo</h1>

    <p>Type a bracket like '[', '(', '{', '&quot;', or '''
    and <a href="../doc/manual.html#addon_closebrackets">the addon</a>
    will auto-close it. Type the closing variant when directly in
    front of a matching character and it will overwrite it.</p>

    <p>If you backspace over a starting bracket while inside empty brackets
    (e.g. <code>{|}</code>), it will delete the closing bracket for you.</p>
