This is a meta-template for development of additional, more specific templates. If you intend to use the template inline in articles or other pages, use {{crossreference}} (shortcuts or {{crossref}} and {{xref}}) or other specific templates based on this metatemplate, e.g. {{see above}} and {{see below}}.
The {{Hatnote inline}} meta-template formats text into a standardized style for an inline (not block-level) variant of a Wikipedia:Hatnote, a short note placed at the point of insertion, to link to more information or otherwise cross-reference another Wikipedia page. like this:
Hatnotes inside definitions in template-formatted glossaries, provided by the {{ghat}} template. These are printworthy, as they refer to content on the same page.
The meta-template does not automatically create links of any kind. Links and other desired formatting must be explicitly added, using normal Wikipedia markup.
Parameters
This template accepts the following parameters:
|1= or |text= or |content= the inline hatnote's text (required). While the explicit naming of this parameter with 1=, text=, or content= is not required, it is always safest to use it this way, since any = character in the text will break the template if the parameter is unnamed.
|class= or |extraclasses= any extra CSS classes to be added. This should not normally be used.
|selfref=no – if set to no (or n, false, 0, etc.) removes the default CSS class selfref, used to denote unprintworthy self-references to Wikipedia
(see Template:Selfref for more information). This option should not be used to indicate a non-selfref on cross-article links, only links within the same article (and the derived shorthand templates {{See above}} and {{See below}} do this automatically). The parameter alias |printworthy=yes (or with any other value, like y, true, 1, etc.) has the same effect as |selfref=no. Note the attempting to manually supply a "this is a selfref" value with |selfref=yes or |printworthy=no will not have the desired effect (which is the default anyway); the meta-template is set to selfref by default, since most uses are self-references (only those within the same article as the template are not).
|category= if set to no (or n, false, 0, etc., suppresses the error-tracking category (Category:Hatnote templates with errors). This only has an effect if the first positional parameter (the hatnote text) is omitted. This should not normally be used.
Technical details
The meta-template places an HTML <span>...</span> container around the text entered as its first, required parameter, upon which it provides standardized formatting (italicized in most displays, and only stylistically, not as semantic emphasis); it also uses CSS classes to isolate the contained code to make sure that it is interpreted correctly and can be acted upon independently of true article content.
The HTML code produced by this template looks like this:
<span class="hatnote">hatnote text</span>
This is the same class used by the <div>-based {{hatnote}} template, the block display of which is controlled by a separate div.hatnote directive in Mediawiki:Common.css.
{{Crossreference}} (a.k.a. {{Crossref}}, {{Xref}}) – Template for inline crossreferences to (usually) other Wikipedia pages (unprintworthy in most cases)
