Answer: continuity is the term used to denote visual relationship between two or more individual designs. The answer is continuity.
Explanation: The law of continuity ,the items placed in a certain row or direction are seen as a group . The Law of Continuity can be applied both to the design aspect and to the content aspect of elements . Eyes can easily and naturally follow elements that are arranged along a continuous line, those elements are therefore perceived as a unit. The elements that follow each other, either logically or visually, are perceived as unit as well.
When designers produce templates, they place elements into the layout suchwise that user can easily guess that these elements can be considered as a group. These elements are easily traced and share a common direction line. Try to find “these lines” in your everyday experience and understand how they affect your perception .
