How to use background-image from style.css

I placed my image in `public/bg.jpg`. I want to make this a background image to my `src/home/style.css`.

**src/home/style.css**
```
body {
background-image: url('swing.jpg');
}
```

**src/home/index.js**
```
import React, { PropTypes } from 'react';
import Layout from '../../components/Layout';
import s from './styles.css';

class HomePage extends React.Component {
render() {
return (


);
}

}

export default HomePage;

```

Start by comparing the asset location at public/bg.jpg with the stylesheet referenced by src/home/index.js, then inspect src/home/style.css and the rendered HomePage in a browser. Done means the page visibly uses the image as its background without breaking the existing stylesheet import.
