<p>This example shows how to create a `Dial` widget using background images for the ring and the handle.</p>

<h3>Creating a Dial With Images as Backgrounds</h3>

<p>A `Dial` can be created that has its presentation determined by background images.

This can be done with CSS, providing the images can be contained within the dimensions of the `Dial` elements.

</p>

<h4>The Markup</h4>

<p>The only markup requirement is an element to contain the `Dial`</p>

```

<div id="demo"></div>

```

<h4>The JavaScript</h4>

<p>The same JavaScript can be used as in the basic Dial example.</p>

<p>`Dial` extends the `Widget` class, following the same pattern

as any widget constructor, accepting a configuration object to

set the initial configuration for the widget.</p>

<p>After creating and configuring the new `Dial`,

call the `render` method on your `Dial` object passing it

the selector of a container object.

This renders it in the container and makes it usable.</p>

<p>Some commonly used configuration attributes are shown below.

</p>

```

YUI().use('dial', function(Y) {

var dial = new Y.Dial({

min:-220,

max:220,

stepsPerRevolution:100,

value: 30

});

dial.render("#demo");

});

```

<h4>The CSS</h4>

<p>

In this example we add an image of a ball bearing to the dial `handle` object's background, this is the class `yui3-dial-handle`.</p>

<p>We'll also add an image of a circle of radial lines to the background ring object.

To make these changes, we only need to do two things. </p>

<ol>

<li>Remove some of the CSS styling on the elements we want to display as images.</li>

<li>Add the background URL to the image rule of the selectors of those objects as shown below.</li>

</ol>

```

{{>dial-image-background-source-css}}

```
