Separation of presentation and content

Separation of presentation and content (or "separate content from presentation", a special case of the form and content principle) is a common idiom, a design philosophy, and a methodology applied in the context of various publishing technology disciplines, including information retrieval, template processing, web design, web development, word processing, desktop publishing, and model-driven development. It is a specific instance of the more general philosophy, separation of concerns.
