 LaTeX attempts to follow the design philosophy of separating presentation from content, so that authors can focus on the content of what they are writing without attending simultaneously to its visual appearance.In preparing a LaTeX document, the author specifies the logical structure using simple, familiar concepts such as "chapter", "section", "table", "figure", etc., and lets the LaTeX system handle the formatting and layout of these structures.As a result, it encourages the separation of the layout from the content — while still allowing manual typesetting adjustments whenever needed.
