function backgrounds() {
    for (var _len = arguments.length, properties = new Array(_len), _key = 0; _key < _len; _key++) {
      properties[_key] = arguments[_key];
    }
    return {
      background: properties.join(', ')
    };
  }
Shorthand that accepts any number of background values as parameters for creating a single background statement.
@example
// Styles as object usage
const styles = {
  ...backgrounds('url("/image/background.jpg")', 'linear-gradient(red, green)', 'center no-repeat')
}

// styled-components usage
const div = styled.div`
  ${backgrounds('url("/image/background.jpg")', 'linear-gradient(red, green)', 'center no-repeat')}
`

// CSS as JS Output

div {
  'background': 'url("/image/background.jpg"), linear-gradient(red, green), center no-repeat'
}
