<h2>Placeholder demo</h2>
<form><textarea id="code" name="code" placeholder="Code goes here..."></textarea></form>
<p>The <a href="../doc/manual.html#addon_placeholder">placeholder</a>
plug-in adds an option <code>placeholder</code> that can be set to
make text appear in the editor when it is empty and not focused.
If the source textarea has a <code>placeholder</code> attribute,
it will automatically be inherited.</p>
