reveal.js comes with a broad range of features including [nested slides](https://github.com/hakimel/reveal.js#markup), [markdown contents](https://github.com/hakimel/reveal.js#markdown), [PDF export](https://github.com/hakimel/reveal.js#pdf-export), [speaker notes](https://github.com/hakimel/reveal.js#speaker-notes) and a [JavaScript API](https://github.com/hakimel/reveal.js#api). It's best viewed in a browser with support for CSS 3D transforms but [fallbacks](https://github.com/hakimel/reveal.js/wiki/Browser-Support) are available to make sure your presentation can still be viewed elsewhere.

### States
If you set ``data-state="somestate"`` on a slide ``<section>``, "somestate" will be applied as a class on the document element when that slide is opened. This allows you to apply broad style changes to the page based on the active slide.
Furthermore you can also listen to these changes in state via JavaScript:
```javascript
Reveal.addEventListener( 'somestate', function() {
// TODO: Sprinkle magic
}, false );
```
### Ready event
The 'ready' event is fired when reveal.js has loaded all (synchronous) dependencies and is ready to start navigating.

```
### Slide backgrounds
Slides are contained withing a limited portion of the screen by default to allow them to fit any display and scale uniformly. You can apply full page background colors or images by applying a ```data-background``` attribute to your ```<section>``` elements. Below are a few examples.
```html
<section data-background="#ff0000">
<h2>All CSS color formats are supported, like rgba() or hsl().</h2>
</section>
<section data-background="http://example.com/image.png">
<h2>This slide will have a full-size background image.</h2>
</section>
<section data-background="http://example.com/image.png" data-background-size="100px" data-background-repeat="repeat">
<h2>This background image will be sized to 100px and repeated.</h2>
</section>
```
Backgrounds transition using a fade animation by default. This can be changed to a linear sliding transition by passing ```backgroundTransition: 'linear'``` to the ```Reveal.initialize()``` call.
### Internal links
It's easy to link between slides. The first example below targets the index of another slide whereas the second targets a slide with an ID attribute (```<section id="some-slide">```):
