 Elements have the following geometry properties:
 
 - `offsetParent` -- is the nearest positioned ancestor or `td`, `th`, `table`, `body`.
-- `offsetLeft/offsetTop` -- coordinates relative to the upper-left edge of `offsetParent`.
+- `offsetLeft/offsetTop` -- coordinates of the upper-left corner relative to the `offsetParent`.
 - `offsetWidth/offsetHeight` -- "outer" width/height of an element including borders.
 - `clientLeft/clientTop` -- the distances from the upper-left outer corner to the upper-left inner (content + padding) corner. For left-to-right OS they are always the widths of left/top borders. For right-to-left OS the vertical scrollbar is on the left so `clientLeft` includes its width too.
 - `clientWidth/clientHeight` -- the width/height of the content including paddings, but without the scrollbar.
