There are a number of types of pages that are used repeatedly on MDN. This article describes these page types, their purposes, and gives examples of each.
There are three broad categories of page types on MDN, though some page types fall into more than one category.
- Reference pages describe the details of something, and are organized according to the structure of the thing described.
- Guide pages describe how to do something or use something, and are organized based on the goals of the reader.
- Navigation pages exist primarily to provide links to other pages, usually about related topics.
API landing page
An API landing page provides an overview of what a particular API does, then contains links to the documentation for each of the interfaces, globals, functions, etc. offered by the API. It does not link directly to specific methods or properties within the API's classes, except in the context of the overview text. It is primarily a navigation page, but also functions as an at-a-glance reference page for the API.
API reference page
An API reference page lists all the methods, properties, events, and so forth, belonging to a particular interface or class. It provides an overview of what the class or interface does or is used for, and gives links to the documentation for each of these members. It is more granular than an API landing page, which typically links to multiple API reference pages.
API reference subpage
An API reference subpage is a child of an API reference page. It documents a single member in detail.
A conceptual page is a guide page that explains or teaches something. Generally, if a page contains primarily prose, and doesn't fall into another page type, it's probably a conceptual page. An extended discussion of a topic might be spread across multiple conceptual pages, and linked using
A glossary page contains a brief explanation of a term, topic, or concept. The first paragraph should be a simple, self-contained description of the term, no more than a couple sentences. This can be followed by links to further information in the Learn more section. If the page grows to more than a screenful or so, it's too long, and should be converted to a conceptual page. See How to write and reference an entry in the glossary for more details.
A landing page serves as a menu, of sorts, for its subpages, and is therefore primarily a navigation page. A landing page layout is typically used for the root page of a tree of pages about a particular topic. It opens with a brief summary of the topic, then presents a structured list of links to its subpages, and optionally, additional material that be useful to the reader. The list of subpages can be generated automatically using the
