offset()

This returns an object with top, left, width, height, borderLeft, borderTop, marginLeft, marginTop, scrollLeft, scrollTop, pageXOffset, pageYOffset. The top and left values include the scroll offsets but the scrollLeft and scrollTop properties of the returned object are the combined scroll offets of the parent elements (not including the window scroll offsets). This is not the same as the element's scrollTop and scrollLeft. For accurate readings make sure to use pixel values.
