s/all에서 썸네일 구경하다가 눈갱 당해서 만들었습니다
기존에 사용하던 썸네일 크기조절 코드에 추가된거라 이부분이 싫으시다면 AI를 활용해 보세요
기본적으로 모든 서브의 이미지와 본문은 비활성화 상태가 됩니다
우측에 서브 정보 하단부에 스위치가 추가됩니다
이렇게 허용 스위치를 켜지 않는다면
게시물에 호버했을때 썸네일이 나오지 않고
본문에 들어갔을때
선제적으로 본문 전체를 블러 처리하고 모든 이미지에 블러 처리 완료되면 본문 블러를 비활성화 합니다(이미지만 블러됨)
아까 말한 스위치를 이 상태에서 활성화시 이미지에 블러는 제거됩니다
s/all에서는 허용한 서브 목록들을 끌수만 있으며 추가는 직접 서브에 방문해야합니다
클로드 AI 활용해서 만든 코드이며, 더 좋은 코드를 위해 마음대로 재 가공 하셔도 좋습니다 MIT
