In common speech, the term column (from the Latin columna) refers to the vertical sections in a newspaper or magazine, or also to a brief, regularly publish opinion article in this format. In technical printing terminology, a column is the text designed for a page of a printed product. The titles at the top edge of a page are called heads. In this context, a distinction is made between running heads and folios. The former vary according to the content of the respective page. The latter do not change and contain, for example, fixed section titles or page numbers.
