offset() Get the element (HTML element) from the pixel document edge, the left edge, and windows.,
OffsetLeft is set if the orientation of non STATIC elements, it is relative to their position! But should notice is not completely positioning distance, but the objects around offsetWidth, that is to add the left margin distance!
