One of the Principles of Design Followed by a Layout

One of the principles of design followed by a layout artist is that:

A) the total headline area should always fill 80 percent of the ad.
B) ads should comprise multiple dominant visuals that occupy 10 percent of the total area.
C) the space within the ad should be divided into asymmetrical units.
D) a directional pattern should be evident so that the reader knows in what sequence to read.
E) all elements of the ad should have equal emphasis in order to avoid dominating the others.
Advertising author Roy Paul Nelson points out that the principles of design are to the layout artist what the rules of grammar are to the writer. The basic rules include the following:
(a) The design must be in balance.
(b) The space within the ad should be broken up into pleasing proportions.
(c) A directional pattern should be evident so the reader knows in what sequence to read.
(d) Some force should hold the ad together and give it unity.
