offsetHeight: Get the height of the object relative to the layout or the parent coordinate specified by the parent coordinate offsetParent property
offsetLeft: Get the calculated left position of the
object relative to the layout or the parent coordinate specified by the offsetParent property offsetTop: Get the object relative to the layout or the offsetTop property The calculated top position of the specified parent coordinates
event.clientX the horizontal coordinate
relative to the document event.clientY the vertical coordinate relative to the document
event.offsetX the horizontal coordinate
relative to the container event.offsetY the vertical coordinate relative to the container

The differences between IE and FireFox 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 needs to be mentioned: the margin property in CSS has nothing to do with clientWidth, offsetWidth, clientHeight, and offsetHeight) The
