👩🏻‍💻 CSS

  • :root에서는 전역으로 사용할 색깔을 정의해서 사용했다.
  • currency-select에서 화살표 방향을 맞추는 부분이 조금 까다로웠다.
  • space-between, space-evenly, space-around의 차이점이 헷갈렸다.
    • space-between : 아이템들 사이에 균일한 가격
    • space-around : 아이템들의 둘레(around)에 균일한 간격
    • space-evenly : 아이템들의 사이와 양 끝에 균일한 간격
    • 참고 : 스튜디오밀
  • @media를 사용해서 브라우저의 너비에 맞게 input태그가 조절되도록 사용했다.
