function cover(offset) {
    if (offset === void 0) {
      offset = 0;
    }
    return {
      position: 'absolute',
      top: offset,
      right: offset,
      bottom: offset,
      left: offset
    };
  }
CSS to fully cover an area. Can optionally be passed an offset to act as a "padding".

@example
// Styles as object usage
const styles = {
  ...cover()
}

// styled-components usage
const div = styled.div`
  ${cover()}
`

// CSS as JS Output

div: {
  'position': 'absolute',
  'top': '0',
  'right: '0',
  'bottom': '0',
  'left: '0'
}
