<div id="p1" style="width:300px;"></div>
</p>
<p>
<b>Additional Options</b><br />

<button id="btn2">Show</button><br />
<div id="p2" style="width:50%;"></div>
</p>
<p>
<b>Waiting Bar</b><br />
Wait for a long operation to complete (example will stop after 5 secs):
<button id="btn3">Show</button><br />
<div id="p3"></div>
<span class="status" id="p3text">Ready</span>
</p>
<p>
<b>Custom Styles</b><br />
