"Template:Para" redirects here; not to be confused with Template:Paragraph break or Template:Param.

Usage

This template is for giving examples of template parameter source code (useful in template documentation and talk page discussions of template code).

It must have at least one or two parameters itself. The first parameter is the name of the example parameter to display (this may be empty, but it must be present). The second (optional) parameter is a value for the first example parameter; or, if the first parameter is empty, the second illustrates an example unnamed parameter (which in some cases may serve as a pre-defined parameter that takes no |=value after it, e.g. the |section in {{More citations needed|section}}).

Examples

Code	Result	Notes
{{para|name}}	|name=
{{para|title|The Oxford English Dictionary}}	|title=The Oxford English Dictionary
{{para||section}}	|section	For unnamed parameters; note empty first parameter in the code
{{para|{{var|parameter}}|{{var|value}}}}	|parameter=value

When using literal, pre-specified parameter names and values, simply provide them (as in the first through third examples above). When illustrating hypothetical/example parameter names, or variable or user-definable values, use something like {{var|parameter}} and/or {{var|value}} (as in the last example above).

Parameters

• |1= or first unnamed parameter – the parameter name. Give this parameter as explicitly blank and just fill in parameter 2 when you want to show an unnamed parameter (which, depending on the context, may serve as a valueless parameter name); e.g., {{para|section}} → |section=
• |2= or second unnamed parameter – the value name; e.g., {{para|section|about}} → |section=about.
  • When the first parameter is given but is blank, the second represents an unnamed parameter's value (or a valueless parameter name), and only the parameter is shown with no equal’s sign; e.g., {{para||section}} → |section
• |plain=y (or any other value besides y) – removes the faint border and light-grey background, which may be useful in various situations. The border and text color are set to inherit, to use the colors of the surrounding text. This parameter cooperates with the two below, in that if either are used, the text will be colorized while the border and background will still be removed.
• |mxt=y or |green=y – to apply the style (green monospaced text) that would be applied by {{mxt}}. Since {{para}} contains <code> markup inside its source which would override the color of {{mxt}}, these parameters can be used when {{para}} is used for text inside a passage of {{mxt}} content. This parameter cooperates with |plain= in applying the color but respecting the removal of border and background.
• |!mxt=y or |red=y – same as above, but applies the red of {{!mxt}}, the “bad monospaced example text" template.
• |style= – to apply arbitrary CSS style, for some specialized contextual purpose. Example: |style=background-color: Yellow;. Any color, background-color, or border specified here will override those provided by any of the above parameters, regardless of the order in which the parameters are given in the template. As this template uses a <span> element, only CSS that can apply to inline elements (not block elements) will work. Like the above parameters, it applies to the entire output.
  • B To specifically style the parameter name and/or the value:
    e.g., {{para|page|{{var|'''single''' page number}}}}, {{para|page'''''<u>s</u>'''''|{{var|page '''range''', or '''multiple''' individual pages, or both}}}}
    gives: |page=single page number, |pages=page range, or multiple individual pages, or both

The three tables below describe the family of approximately forty templates built for talking about templates.

There are also some related templates or subjects not found in those tables:

• {{Param}}, for markup of examples of parameter names as they would appear in MediaWiki source code of templates, e.g. {{param|foo}} gives: {{{foo}}}
• {{Parameter2}}, for syntaxhighlight-style formatting, e.g. {{para2|foo|bar}} gives: |foo=bar
• {{Tag|...|attribs}}, for markup of examples of HTML elements' attributes and values; e.g. {{tag|a|attribs=href=/demo.php|o}} gives: <a href=/demo.php>
