x1 (text, image, page element) is supra/aforementioned/previous/earlier/preceding/above/toward the top of the page/screen (flat and primarily two-dimensional display) relative to x2 (text, image, page element) on page/screen/in work x3 according to cultural convention x4.
Because text is usually read horizontally, this word could mean "to the left of" (for left-to-right writing) or "to the right of" (for right-to-left writing), as assessed on each given line; additionally, any horizontal direction within the plane of the display can contribute a nonzero component, so long as x1 is also topward of x2. For texts/writing systems which begin at the bottom of a page (according to physical orientation), then this word refers to that direction instead of the physical top of the page. In other words, this word always is oriented back along the writing/display which, by cultural convention, the user should have already consumed. Can refer to distinct prior pages. Essentially, the entire document is imagined as being displayed upon a single, arbitrarily-long, ordered screen which is wide enough to display at most a single word/character or element per line throughout; in this configuration, x1 precedes and is perforce 'above' x2.
