export default () => {
  const [isSticky, setSticky] = useState(false);
  const ref = useRef(null);
  const handleScroll = () => {
    if (ref.current) {
      setSticky(ref.current.getBoundingClientRect().top <= 0);
    }
  };

  useEffect(() => {
    window.addEventListener('scroll', handleScroll);

    return () => {
      window.removeEventListener('scroll', () => handleScroll);
    };
  }, []);
