For cases where the serif typeface is not desirable (e.g. in blocks of computer code), use {{bxt}}, which substitutes boldfacing, or {{mxt}}, which substitutes a monospaced font. For style examples that break to their own line (e.g. paragraphs), use {{xt2}}.
For examples of bad/wrong style, in red, use {{!xt}}, {{!bxt}}, {{!mxt}}, or {{!xt2}}, respectively.
The {{xtd}} template exists for Insert non-formatted text heredeprecated examples. Its alias {{xtg}} (for "grey") can be used to indicate uncertain, unavailable, disabled, lorem, etc., examples without implying deprecation. The bold, sans-serif equivalent is {{bxtd}} (and {{bxtg}} alias). The mono-spaced equivalent is {{mxtd}}.
The {{xtn}} template is for neutral examples, and has no color change, but is otherwise identical to {{xt}}. It can be used with {{xt}} and {{!xt}} to indicate usage that is neither advised nor advised against or deprecated. The bold, sans-serif equivalent is {{bxtn}}.
Parameters
|text here or |1=text here – The text to which to apply the markup. As with all templates, when the text has any equals characters ("="), explicitly prefix the text with |1= or the template will break.
|title=tooltip text here – Takes text, which cannot be marked up in any way, and displays it as a pop-up "tooltip" (in most browsers) when the cursor hovers over the span
Accessibility
The accompanying change in typeface to a serif or monospaced type style (as in example text) is to make it fully accessible for those with color blindness.
Keep accessibility more broadly in mind, and never construct examples such that a blind person, who may not be able to see the coloration, boldfacing, or monospace font change, cannot understand the examples. Especially indicate, with terms like "not", "don't", "wrong:", etc., that a negative example is a negative one, or with "deprecated", "avoid", etc., that deprecated material is deprecated.
{{!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 Insert non-formatted text heredeprecated (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.
