<label for="slider-2">Input slider:</label>
<input type="range" name="slider-2" id="slider-2" value="25" min="0" max="100" data-theme="a" data-track-theme="b" />
</div>

<p>By adding a <code>data-range-theme</code> attribute to the <code>input</code>, a separate swatch is set for the track between the start- and the handles position.</p>

<pre><code>
&lt;div data-role=&quot;fieldcontain&quot;&gt;
&lt;label for=&quot;slider-3&quot;&gt;Input slider:&lt;/label&gt;
&lt;input type=&quot;range&quot; name=&quot;slider-3&quot; id=&quot;slider-3&quot; value=&quot;25&quot; min=&quot;0&quot; max=&quot;100&quot; <strong>data-theme=&quot;a&quot; data-range-theme=&quot;b&quot;</strong> /&gt;
&lt;/div&gt;
</code></pre>

<p>This will produce a themed slider:</p>
<div data-role="fieldcontain">
<label for="slider-3">Input slider:</label>
<input type="range" name="slider-3" id="slider-3" value="25" min="0" max="100" data-theme="a" data-range-theme="b" />
</div>
</form>
