1. Instructions for using scrollTop and scrollLeft in js

scrollTop refers to the height of the part where the "content in the element" exceeds the "upper boundary of the element".

Obviously, the "content in the outer element" is higher than the "outer element" itself. When the scroll bar is dragged downward, part of the content will be hidden outside the "upper boundary of the outer element", and scrollTop is equal to The height of this "invisible content".

scrollLeft is the same as above.

                        <meta http-equiv="Content-Type" content="text/html; charset=gb2312">        <title>琛ㄥご</title>
