<문제 상황>

배너 이미지를 슬라이드에 채우면 계속 아래에 빈공간이 생기고 사진이 위로 올라가는 문제가 있었음.

<해결과정>

개발자도구에서 확인했을 때 내가 작성한 코드의 문제가 아니라 서버 자체에서 만들어 내는 'User Agent Stylesheet(사용자 에이전트 스타일시트)' 코드로 인해 생긴 문제였음. 스타일에 있는 'ul{(생략)}'코드를 위로 올렸고, margin : auto를 지운 후 padding left로 값을 주고, 배너에 해당되는 ' .section .slidelist > li {}'와'.section .slidelist > li > a img {}'에서의 width 값은 100vw로 주었더니 해결되었음.

vw는 전체길이값 단위
