| A third contributor to the flavor of your web site's interface design is its style-its layout graphics, typefaces, colors and so on. The layout of the site needs to be flexible enough to support changing content and different media types. This requires an underlying grid that at least defines areas for site of company identification, navigation elements, text and imagery. In addition, alignment within the areas should be consistent. For instance, don't center some elements but align others left. Even beyond the basic grid, always look for ways to align, and thus relate, elements to one another.
One way to characterize an interface is by the dimensionality of its graphics: 2D,”2 ½ D” or 3D. The 2D style is similar to the printed page with its emphasis on a structures organization of the text and graphics on a flat surface. An example of the 2 ½ D style is the beveled button, a navigation element that appears raised and clickable. Using this approach you can easily make it clear which parts of the interface are interactive. The 3D style defines a virtual thee-dimensional space , where images of real-world environments and objects are used for navigation and information access.
Typically, dimensionality is closely tied with the metaphor used for the site. For instance, a newspaper or magazine metaphor is best represented in a 2D style. A 2 ½ D style work well for an instrument panel or appliance metaphor. A 3D style can involve anything from illustrations that fake perspective to a render-on-the-fly virtual reality (VRML) representation that lets the visitor more freely through a complex environment. But metaphor and style don't have to match perfectly. For instance, a three-dimensional metaphor such as a house can also be presented in a 2D graphical style, as a blueprint or cross-sectional drawing showing different rooms. |
