[css] Flexbox 실습 - header 만들기

by jade 2024. 1. 13. 12:58

ver2 css 파일에 height 100%를 주는 이유는?
  >> ul의 높이는 콘텐츠의 크기만큼 할당되어 있기 때문에
  처음의 height는 li 와 ul가 같음. 
  
  하지만 li들은 .header2 기준으로 세로 중앙정렬을 해야하기 때문에
  ul.menus는 .header2의 높이를 그대로 가져와서 li의 기준이 되어야함.
  
  border:1px solid black; 으로 ul.menus가 어느정도를 차지하는지 확인해야함
  height:100%가 있을 때와 없을 때를 비교해보자!
