새로 공부한 내용

1. input 태그의 placeholder 속성값 CSS

• 색 적용 방법
  : input::placeholder 와 같은 선택자를 사용하여 color css를 적용한다.

• input 영역 클릭했을 때 텍스트 사라지게 하는 방법 (https://webdir.tistory.com/335)
  : input:focus::placeholder 와 같은 선택자를 사용하여 color로 transparent를 지정한다.

2. 높이 변화 애니메이션
   : 마우스를 갖다대면 나타나는 효과를 적용하는 hover 선택자를 사용한다.
