function backgroundImages() {
    for (var _len = arguments.length, properties = new Array(_len), _key = 0; _key < _len; _key++) {
      properties[_key] = arguments[_key];
    }
    return {

  }
Shorthand that accepts any number of backgroundImage values as parameters for creating a single background statement.
@example
// Styles as object usage
const styles = {
  ...backgroundImages('url("/image/background.jpg")', 'linear-gradient(red, green)')
}

// styled-components usage
const div = styled.div`
  ${backgroundImages('url("/image/background.jpg")', 'linear-gradient(red, green)')}
`

// CSS as JS Output

div {
  'backgroundImage': 'url("/image/background.jpg"), linear-gradient(red, green)'
}
