The elementFromPoint() method of the Document interface returns the topmost element at the specified coordinates.
If the element at the specified point belongs to another document (for example, an iframe's subdocument), the subdocument's parent element is returned (the iframe itself). If the element at the given point is anonymous or XBL generated content, such as a textbox's scroll bars, then the first non-anonymous ancestor element (for example, the textbox) is returned.
If the specified point is outside the visible bounds of the document or either coordinate is negative, the result is null.
If you need to find the specific position inside the element, use Document.caretPositionFromPoint().
