 *     colorStops: ['#00FFFF 0%', 'rgba(0, 0, 255, 0) 50%', '#0000FF 95%'],
 *     extent: 'farthest-corner at 45px 45px',
 *     position: 'center',
 *     shape: 'ellipse',
 *   })
 * }
 *
 * // styled-components usage
 * const div = styled.div`
 *   ${radialGradient({
 *     colorStops: ['#00FFFF 0%', 'rgba(0, 0, 255, 0) 50%', '#0000FF 95%'],
