Position refers to the location of an element relative to its container, typically on the horizontal and vertical axes.
In computing, position closely relates to the geometrical definition of a position or position vector, also known as location vector or radius vector, which is a Euclidean vector that represents the position of a point P in space in relation to an arbitrary reference origin O. Usually denoted x, r or s, it corresponds to the displacement from O to P.
In simplified terms, position is used in reference to the location of a 'child' entity within a two-dimensional or three-dimensional space, the boundaries of which are referred to as the 'container' or 'parent'.
