To indicate text is a variable name. Use for any variable names except those including "I" (uppercase i) and/or "l" (lowercase L); for these, {{varserif}} should be used to ensure a noticeable distinction.
To display parameters as used in code (i.e. with triple braces), especially to indicate relationships between them. May be combined with {{para}} above.
( or {{dc}} ) To indicate deprecated source code in template documentation, articles on HTML specs, etc. The {{dc2}} variant uses strike-through (<blink>) while {{dc|red{{=}}y}} uses red (<blink>).
Intended for transclusion at the end of the documentation for each of the main Semantic markup templates, e.g. as part of a "See also" section such as:
How to manage this template's initial visibility
To manage this template's visibility when it first appears, add the parameter:
|state=collapsed to show the template in its collapsed state, i.e. hidden apart from its titlebar – e.g. {{Semantic markup templates |state=collapsed}}
|state=expanded to show the template in its expanded state, i.e. fully visible – e.g. {{Semantic markup templates |state=expanded}}
|state=autocollapse to show the template in its collapsed state but only if there is another template of the same type on the page – e.g. {{Semantic markup templates |state=autocollapse}}
Unless set otherwise (see the |state= parameter in the template's code), the template's default state is collapsed.
