Remember that fonts with spaces in the name must be wrapped in quotes for CSS.

-> 폰트 이름에 공백이 있는 경우는 꼭 CSS용 따옴표로 감싸야 한다.!!

font-family: "Open Sans";

브라우저 개발자 도구는 border-box로 width를 계산

.label 요소의 width: 270px;을 설정했는데, 개발자 도구로 보면 실제 너비가 288px
이유? CSS의 기본 box-sizing 값이 content-box이기 때문

box-sizing: border-box; 로 해결

➡ box-sizing: border-box;을 사용하면 width가 padding과 border까지 포함한 크기로 설정됨!

이제 width: 270px;이면 padding과 border를 포함해서 정확히 270px 유지됨!

:not(선택자) 이란?

➡ 특정 CSS 규칙을 "제외한" 요소들을 선택하는 가상 선택자
➡ 주어진 선택자와 일치하지 않는 요소들만 스타일을 적용

예제 코드

.daily-value p:not(.no-divider) {
  border-bottom: 1px solid #888989;
}

✅ .no-divider 클래스를 가진 p 태그 제외 하고 border 적용.

각주나 설명글(.note) 스타일 만들기

.note {
  font-size: 0.6rem;
  margin: 5px 0;
  /* padding: 0 8px;
  text-indent: -8px; */
}

여기서 저 주석을 풀어주면!

padding: 0 8px; → 좌우로 8px 패딩 추가 (내용을 안쪽으로 밀어넣음)
text-indent: -8px; → 첫 `줄` 들여쓰기(-8px), 즉 첫 글자를 왼쪽으로 8px 이동
