Abstract: An exemplary system and method for the substantially modular design and construction of web pages and other markup language document content is disclosed as comprising inter alia: a database (5); a document code module (e.g., 135) that is at least partially derived from data in the database (5); and a substantially graphical user interface (200) for inserting (264), removing (242), hiding (244), showing (294), moving (262), modifying (246) or administrating at least one module (e.g., 235) in order to produce at least a portion of a markup language document (100). Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve modular design and/or production of markup language content for any application or operating environment. Exemplary embodiments of the present invention generally provide for the production, publication and administration of web pages that may be readily integrated with an e-commerce storefront.
