Template:Infobox Cosmology

This template produces formatted text, following the guideline for a hatnote.

{{hatnote|Example hatnote text.}} →

Example hatnote text.

Broadly speaking, a hatnote should answer a readers' question (maybe preemptively): Am I on the right page?

Function

This template is primarily used to add a correctly formatted hatnote to a page. Often, but not always, this is a disambiguation link at the top of article pages. It places an HTML div- / div block around the text entered as its only argument, which provides standardized formatting (contents are indented and italicized in most displays); it also isolates the contained code to make sure that it is interpreted correctly.

This template is also used as the "meta-template" for additional specialized disambiguation link templates.

The template does not automatically create links of any kind. Links and other desired formatting must be explicitly added, using normal Wikipedia markup.

Usage

Template:((hatnote|textTemplate:))

Parameters
