A typeface is like a chair
A figure is an element or shape placed on a page, canvas, or other background. Ground is the space of the page.
A figure is also called object, form, element, or positive shape. Ground is alternately called space, residual space, white space, or field.
Figure-ground theory states that the space that results from placing figures should be considered as carefully as the figures themselves.
Space is called negative space if it is unshaped after the placement of figures. It is positive space if it has a shape.
