<h1>Dual-thumb Slider with range highlight</h1>
<div class="exampleIntro">
<p>This example demonstrates a horizontal dual-thumb Slider with custom code to add a highlight to the bounded range. Some characteristics to note include the following:</p>
<ul>
<li>The thumbs are set on a slide bar with a 300 pixel range.</li>
<li>The thumbs are configured with a 12 pixel tick size.</li>
<li>Clicking on the background will animate the nearest thumb.</li>
</ul>
