var left=10;//상자 왼쪽 위치
var top = 20;//상자에 위치

이 두 정의의 구체적인 용도가 무엇인지 모르겠습니다.
엄격한 인증 하에서는 어떻게 조정해도 10PX 정도의 차이가 나는데 왜 그럴까요?
크기를 변경해도 효과에는 영향이 없는 것 같습니다.

원리:
pixelTop과 offsetTop은 다르며, pixelTop은 실제로 숫자입니다. 상의 형태. 그리고 offsetTop은 객체의 실제 오프셋입니다.
처음에는 이 fk 객체의 상단이 정의되지 않아 pixelTop이 0이고, 실제 margin 값인 body의 margin이 존재하기 때문에 offsetTop은 0이 아닙니다.
