Unity Read Milton Glaser on Design Unity is an important concept in design. To make all the elements on the page appear to be unified, connected, and interrelated, there needs to be a visual relationship between the separate elements. Even if the separate elements are not physically close on the page, they can appear connected, related, unified with the other information simply by their placement. Take a look at designs you like. No matter how wild and chaotic a well designed piece may initially appear, you can always find the unity within.
Unity is the final goal of layout.
