In most practical cases we can use `offsetParent` to get the nearest CSS-positioned ancestor. And `offsetLeft/offsetTop` provide x/y coordinates relative to it's left-upper corner.
In most practical cases we can use `offsetParent` to get the nearest CSS-positioned ancestor. And `offsetLeft/offsetTop` provide x/y coordinates relative to it's upper-left corner.
In the example below the inner `<div>` has `<main>` as `offsetParent` and `offsetLeft/offsetTop` shifts from its left-upper corner (`180`):

Elements have the following geometry properties:
- `offsetParent` -- is the nearest positioned ancestor or `td`, `th`, `table`, `body`.
- `offsetLeft/offsetTop` -- coordinates relative to the left-upper edge of `offsetParent`.
- `offsetLeft/offsetTop` -- coordinates relative to the upper-left edge of `offsetParent`.
- `offsetWidth/offsetHeight` -- "outer" width/height of an element including borders.
- `clientLeft/clientTop` -- the distance from the left-upper outer corner to its left-upper inner 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.
- `clientLeft/clientTop` -- the distance from the upper-left outer corner to its upper-left inner 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.
- `scrollWidth/scrollHeight` -- the width/height of the content including the scrolled out parts. Also includes paddings, but not the scrollbar.
- `scrollLeft/scrollTop` -- width/height of the scrolled out part of the element, starting from its left-upper corner.
- `scrollLeft/scrollTop` -- width/height of the scrolled out part of the element, starting from its upper-left corner.
All properties are read-only except `scrollLeft/scrollTop`. They make the browser scroll the element if changed.
