This template is used to insert a quick and easy warning or negative notice with high visibility (because it is red) on project and discussion pages (like the following sentence). This template cannot be used in articles. In situations where color is not relevant (color blindness, screen readers, etc.), it renders exactly the same as {{strong}} (to which it is a CSS-styled call). This template is only for use in template documentation, guidelines, and other Wikipedia-internal purposes. It is the opposite of the {{stronggood}} template.
{{strongbad|important text}}
or, if the important text contains an equals sign:
{{strongbad|1=important text}}
These both render as:
important text
It is safest to always use the |1= syntax.
This template puts intentional and explicit <strong>...</strong> (importance, seriousness, or urgency) HTML markup around the text provided as the first parameter.
Because some people are color blind, and some use screen readers, this template should not be used in a manner in which only the color indicates the difference between the content being marked up and other content; it's simply a visual aid for those who can use it.
{{!mxt}} same as {{!xt}} but uses mono-spaced font; used for incorrect or strongly deprecated code/output/input examples and should usually be wrapped in <code>, <samp>, or <kbd> as appropriate; see also {{dc}} and its variants below
{{!xts}} same as {{!xt}} but also strikes through the text
{{dcr}} inline strongly deprecated or deleted material; {{dc2}} variant has strikethrough (they both use the <del> element, and do not add monospace font on their own; can be used in mainspace (articles), and where necessary wrapped in <code>, <samp>, or <kbd>); see also {{dc}} below
{{xtd}} inline deprecated (or uncertain, unavailable, lorem, etc.) example text, in grey
{{mxtd}} same as {{xtd}} but uses mono-spaced font
{{dc}} inline deprecated or deleted material; (uses the <del> element, and does not add monospace font on it own; can be used in mainspace (articles), and where necessary wrapped in <code>, <samp>, or <kbd>); see also {{dcr}} above
{{xtn}} inline neutral example text, with no color change, when none of the above applies; used for "permissible" examples neither favored nor deprecated
{{bxtn}} same as {{xtn}} but uses boldface; it still applies a CSS class, so it's not simply boldfacing
{{mxtn}} same as {{xtn}} but uses mono-spaced font; this is a good template to use when the shaded box formatting of <code>...</code> might be undesirable, or the semantics of it is incorrect in the context
{{strongbad}} – for introducing something as deprecated or issuing some other warning in documentation, e.g.: Not for use in mainspace.
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, {{var serif}} 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
To display parameter values lightly bordered; replaces <code>...</code>, especially when value contains embedded or leading/trailing blanks; visualized here with middot (·) but can use ␠, ▯, or any character.
To showcase with colors in horizontal format the syntax of any template, while providing an easy way to display placeholder texts using colons as separators
"Ensure the <syntaxhighlight lang="text" class="" id="" style="" inline="1">alt=</syntaxhighlight> parameter ..."
To indicate text is source code. To nest other templates within {{code}}, use <code>...</code>. {{codett}} differs only in styling: <syntaxhighlight lang="text" class="" id="" style="" inline="1">someMethod</syntaxhighlight> becomes <syntaxhighlight lang="text" class="" id="" style="background:none; border:none; color:inherit; padding: 0px 0px;" inline="1">someMethod</syntaxhighlight>
( or {{dc}}) To indicate deprecated source code in template documentation, articles on HTML specs, etc. The {{dc2}} variant uses strike-through (<blink>) while {{dcr}} uses red (<blink>).
To showcase with colors and multiple lines (vertical format) the syntax of any template, while providing an easy way to display placeholder texts using colons as separators
