styled-components 적용 & 사용

// svg를 컴포넌트 import하듯이 import
import Cart from '/public/images/icon-shopping-cart.svg';

// styled-components의 확장 기능을 사용해서 svg 스타일링
const CartIcon = styled(Cart)`
  path {
    stroke: blue;
  }
  &:hover {
    path {
      stroke: red;
    }
  }
`;

const NavBar = () => {
  return (
    <nav>
      <CartIcon width={32} height={32} />
    <nav>
  );
};

export default NavBar;
