HTML precise positioning: scrollLeft, scrollWidth, clientWidth, offsetWidth
scrollHeight: Gets the scroll height of the object.
scrollLeft: Set or get the distance between the left boundary of the object and the leftmost end of the currently visible content in the window
scrollTop: Set or get the distance between the top of the object and the top of the visible content in the window
scrollWidth: Get the scroll width of the object
offsetHeight: Gets the height of the object relative to the layout or the parent coordinate specified by the parent coordinate offsetParent property
offsetLeft: Gets the calculated left position of the object relative to the layout or parent coordinates specified by the offsetParent property
offsetTop: Gets the calculated top position of the object relative to the layout or the parent coordinate specified by the offsetTop property
Horizontal coordinates relative to the document
Vertical coordinates relative to the document
Horizontal coordinates relative to the container
Vertical coordinates relative to container

IE, FireFox differences are as follows:
IE6.0、FF1.06+：
clientWidth = width + padding
clientHeight = height + padding
offsetWidth = width + padding + border
offsetHeight = height + padding + border
IE5.0/5.5：
clientWidth = width - border
clientHeight = height - border
offsetWidth = width
offsetHeight = height
(It should be mentioned that the margin attribute in CSS has nothing to do with clientWidth, offsetWidth, clientHeight, and offsetHeight)

Yesterday, I changed the layout for some pages in the project. After the replacement, I found that some js was not working well. The page width obtained by such a statement is 0. After some google, I realized that the new page lacked a reference to the W3C standard, resulting in invalidation:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http:///TR/xhtml1/DTD/">
If you add this line to the page
In IE:
==> BODY object width
==> BODY object height
==> Visible area width
==> Visible area height
In FireFox：
==> BODY object width
==> BODY object height
==> Visible area width
==> Visible area height
In Opera:
==> Visible area width
==> Visible area height
==> Page object width (i.e. BODY object width plus Margin width)
==> Page object height (i.e. BODY object height plus Margin height)
If there is no standard for W3C,
IE is:
==> 0
==> 0
FireFox is:
==> Page object width (i.e. BODY object width plus Margin width) ==> Page object height (i.e. BODY object height plus Margin height)
Opera is:
==> Page object width (i.e. BODY object width plus Margin width) ==> Page object height (i.e. BODY object height plus Margin height)
