position Position

Typically indicates whether a display object (for example, figure, table, boxed text) must be anchored in its exact location within the text or may float to a different location in the document (for example, to the top of the next page, into the next column, within a separate window). Also used to indicate that the display object should be placed in the margin or used as a background image behind the text.
