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.
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>).
