<h1>Progress Bar</h1>
<p>
<b>Basic Progress Bar</b><br />
Deferred rendering, dynamic show/hide and built-in progress text:
<button id="btn1">Show</button><br />
<div class="status" id="p1text">Nothing to see here.</div>
<div id="p1" style="width:300px;"></div>
</p>
<p>
<b>Additional Options</b><br />
Rendered on page load, left-aligned text and % width:
<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 />
Rendered like Windows XP with custom progress text element:
<button id="btn4">Show</button><br />
<div id="p4" style="width:300px;"></div>
<div class="status"><b>Status:</b> <span id="p4text"></span></div>
</p>
</body>
