# spin.js
An animated CSS3 loading spinner with VML fallback for IE.
* No images, no external CSS
* No dependencies
* Highly configurable
* Resolution independent
* Uses VML as fallback in old IEs
* Uses @keyframe animations, falling back to setTimeout()
* Works in all major browsers, including IE6
* Small footprint (~1.9K gzipped)
* MIT License
## Usage
```javascript
new Spinner({color:'#fff', lines: 12}).spin(target);
```
For an interactive demo and a list of all supported options please refer to the [project's homepage](http://fgnass.github.com/spin.js).

<h2>Features</h2>
<ul>
<li>No images, no external CSS</li>
<li>No dependencies (jQuery is <a href="#jquery">supported</a>, but not required)</li>
<li>Highly configurable</li>
<li>Resolution independent</li>
<li>Uses VML as fallback in old IEs</li>
<li>Uses @keyframe animations, falling back to setTimeout()</li>
<li>Works in all major browsers, including IE6</li>
<li>MIT License</li>
</ul>
<h2 id="usage">Usage</h2>
<pre class="prettyprint">
var opts = {
lines: <span id="opt-lines" class="lit">12</span>, // The number of lines to draw
length: <span id="opt-length" class="lit">7</span>, // The length of each line
width: <span id="opt-width" class="lit">5</span>, // The line thickness
radius: <span id="opt-radius" class="lit">10</span>, // The radius of the inner circle
rotate: <span id="opt-rotate" class="lit">0</span>, // The rotation offset
color: '#000', // #rgb or #rrggbb
speed: <span id="opt-speed" class="lit">1</span>, // Rounds per second
trail: <span id="opt-trail" class="lit">100</span>, // Afterglow percentage
shadow: <span id="opt-shadow" class="kwd">true</span>, // Whether to render a shadow
hwaccel: <span id="opt-hwaccel" class="kwd">false</span>, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: 'auto', // Top position relative to parent in px
left: 'auto' // Left position relative to parent in px
};
var target = document.getElementById('foo');
var spinner = new Spinner(opts).spin(target);
</pre>
<p>
The <code>spin()</code> method creates the necessary HTML elements and starts the animation. If a target
element is passed as argument, the spinner is added as first child and horizontally and vertically centered.
</p>
<h3>Manual positioning</h3>
<p>
By default the spinner is centered within the target element. Alternatively you may specify a <code>top</code> and
<code>left</code> option to position the spinner relative to the target element.
</p>
<p>
In order to manually insert the spinner into the DOM you can invoke the <code>spin()</code> method without any
arguments and use the <code>el</code> property to access the HTML element:
</p>
<pre class="prettyprint">
var spinner = new Spinner().spin();
target.appendChild(spinner.el);
</pre>
<p>
The returned element is a DIV with <code>position:relative</code> and no height. The center of the spinner
is positioned at the top left corner of this DIV.
</p>
<h3>Hiding the spinner</h3>
<p>
To hide the spinner, invoke the <code>stop()</code> method, which removes the UI elements from the DOM and stops
the animation. Stopped spinners may be reused by calling <code>spin()</code> again.
</p>
<h3 id="jquery">jQuery plugin</h3>
<p>
Spin.js does not require jQuery. Anyway, if you use jQuery (or zepto.js) you may use the following plugin:
</p>
<pre class="prettyprint">
$.fn.spin = function(opts) {
this.each(function() {
var $this = $(this),
data = $this.data();
if (data.spinner) {
data.spinner.stop();
delete data.spinner;
}
if (opts !== false) {
data.spinner = new Spinner($.extend({color: $this.css('color')}, opts)).spin(this);
}
});
return this;
};
</pre>
<p>
Alternatively you may use this <a href="https://gist.github.com/1290439">advanced version</a> written by Bradley Smith.
</p>
