A style, or theme, is a consistent idea used throughout a website to create a feeling of completeness.
These themes often follow period styles. Examples of this are Louis XV, Louis XVI, Victorian, Islamic, Feng Shui, International, Mid-Century Modern, Minimalist, English Georgian, Gothic, Indian Mughal, Art Deco, and many more.
The evolution of website decoration themes has grown to include themes not necessarily consistent with a specific period style allowing the mixing of pieces from different periods. Each element should contribute to form, function, or both and maintain a consistent standard of quality and combine to create the desired design.
