A style guide is a set of standards used for editing and formatting documents. There are different types of style guides for branding, design, writing, coding, and more. Major style guides include the Associated Press (AP) style guide, the Chicago Manual of Style (CMS), the Modern Language Association (MLA) style guide, and the American Psychological Association (APA) style guide. When creating an editorial style guide, decisions need to be made about spelling, abbreviations, citations, dates, page layout, lists, images, fonts, tables, titles, footnotes, numbers, names, bibliographies, and graphic elements like color palettes, logos, and photos.
