평행사변형

평행사변형의 구성은skew()의 변형 속성을 통해 직사각형을 대각선으로 잡아당겨 얻을 수 있습니다(스큐에 사용되는 좌표계는 세로 방향의 X축과 가로 방향의 Y축을 가지며, 이는 공통 좌표계와 반대입니다).

이는 왜곡된 콘텐츠 문제를 해결할 뿐만 아니라 HTML 구조가 여전히 이전처럼 깨끗합니다. 단, 의사 요소에 의해 생성된 패턴은 콘텐츠와 겹치므로 배경이 설정되면 콘텐츠를 덮게 되므로 z-index: -1을 추가해야 합니다.

마름모 그림

정사각형을 기준으로 한다면 마름모는 45도 회전된 정사각형 패턴입니다. 외부 div를 45도 회전한 다음 내부 img를 반대 방향으로 45도 회전시키는 것을 생각하기 쉽습니다. 다음과 같은 패턴이 얻어집니다.
