Knobby.js is a jQuery plugin that turns a number input into a nice clean knob control with support for mouse drag and touch events.

How to use it:

1. Load a CSS theme of your choice into the head section.

<link rel="stylesheet" href="jquery.knobby.light.css">
<!-- OR -->
<link rel="stylesheet" href="jquery.knobby.dark.css">

2. Load the jQuery Knobby.js script after jQuery JavaScript library.

<script src="jquery.js"></script>
<script src="jquery.knobby.js"></script>

3. Create a number input field on your webpage.

<input type="number" name="demo" 
       turn="3" 
       value="0" 
       min="0" 
       max="1000" 
       step="25"
>

4. Initialize the plugin to generate a light themed knob.

$("input[type=number]").knobby();

$("input[type=number]").knobby({

  // number of full circles from min to max
