<!-- ============================================================ -->
<h2>Ranges:</h2>
<p>Like <code><input type="range"></code>, manipulates a number with optional conversions.</p>
<div data-example>
<pre><code class="language-javascript">
const s = {
value1: 40,
value2: 50,
value3: 80,

gui.add(s, 'value2', 0, 100, 1); // 0 to 100 by in steps of 1
gui.add(s, 'value3', 0, 100, 5); // 0 to 100 by steps of 5
