Every time you change the layout of your pages, the user is forced to adjust to a new interface. Already, when linking from one Web site to another, users are confronted with a new environment. You have the power to make a conscious decision to shift things.
Consistency applies to other aspects of design as well.
In your images, navigation buttons and other graphical elements, maintaining a consistency in fonts, appearance, and functionality all strengthen your pages. Designers call this repetition . Clicking on the first icon, an unlabeled picture of Elvis, does absolutely nothing. Positioned next to that icon is an unlabeled button, an orange. This button sends e-mail to Elvis.
