  /* do your action */
}

ReactDOM.render(
  <Coverflow width="960" height="500"
    displayQuantityOfSide={2}
    navigation={false}
    enableScroll={true}
    clickable={true}
    active={0}
    >
    <img src='image/path' alt='title or description' data-action={action} />
    <img src='image/path' alt='title or description' data-action="http://andyyou.github.io/react-coverflow/"/>
    <img src='image/path' alt='title or description' data-action="http://andyyou.github.io/react-coverflow/"/>
  </Coverflow>,

  document.querySelector('.content')
);
```

#### Options

* displayQuantityOfSide [number]: The number of display image from center to the one side end.
* navigation [boolean]: Enable navigation buttons (prev, next). (defalut: false)
* enableHeading [boolean]: Show or hide the heading form img tag alt. (defalut: true)
* enableScroll [boolean]: Enable scrolling feature.
* media [object]: To support media query, if you want responsive with parent element you can ignore `width` and `height` props or set it to `auto`.
* active [number]: The index of images
* clickable [boolean]: On/Off clickable of images, once set to false will disable whole click ability of images. Default is `true`.
* currentFigureScale [number]: The scale factor (float) to be applied on the main image. (default: 1.2)

```js
media={{
  '@media (max-width: 900px)': {
    width: '600px',
    height: '300px'
  },
  '@media (min-width: 900px)': {
    width: '960px',
    height: '600px'
  }
}}
```

#### Responsive

Now, you can use `media` props to support responsive design. The syntax part is come form [Radium](http://projects.formidablelabs.com/radium/)
You can reference to this [doc](https://github.com/FormidableLabs/radium/tree/master/docs/guides#media-queries).

* 2016-09-13 If you need RWD you should add `<StyleRoot>`

```js
ReactDOM.render(
  <StyleRoot>
    <Coverflow
      displayQuantityOfSide={2}
      navigation={true}
      enableHeading={true}
      active={0}
      media={{
        '@media (max-width: 900px)': {
          width: '600px',
          height: '300px'
        },
        '@media (min-width: 900px)': {
          width: '960px',
          height: '600px'
        }
      }}
      >
      <img src='images/album-1.png' alt='Album one' data-action="https://facebook.github.io/react/"/>
      <img src='images/album-2.png' alt='Album two' data-action="http://passer.cc"/>
      <img src='images/album-3.png' alt='Album three' data-action="https://doce.cc/"/>
