Template:Tnull

Template documentation[view] [edit] [history] [purge]

This template, often abbreviated as {{tnull}}, is used to provide stylized formatting to template displays without actually using the template itself.

Parameters

With the exception of alttext, the named parameters are toggles that are either omitted (default in most cases) or activated (by being assigned a value such as "on", "yes", "true", "include", etc.). They may be included in any order (see Examples below). Certain templates have the parameter "on" by default; see the main table for all alternate options.

bold	Renders the template link/name in bold	{{example}}	{{tlb}}, {{tlxb}}
code	Display output using HTML <code>...</code> tags (monospaced font)	{{example}}	{{tlc}}, {{Template link expanded}}, etc.

This template can take any number of unnamed parameters as parameters accompanying the template link (or name); see Examples below.

Examples

Note

On the source sister projects, en.wikipedia and Meta, X0, X1, X2, …, X9 are sandbox templates for experimentation on involved templates that need be in template space. An auto-cleansing software facility exists that might be used to duplicate the facility on other Sister projects.
