''Description lists''<!--HTML5 name--> (formerly ''definition lists''<!--HTML4 name-->, and a.k.a. ''association lists''<!--draft HTML5 name-->) consist of group names corresponding to values. Group names (terms) are in bold. Values (definitions) are indented. Each group <em>must</em> include one or more definitions. For a single or first value, the <code>:</code> can be placed on the same line after <code>;</code> – but subsequent values must be placed on separate lines.
{{hatnote-inline|Do not use a semicolon (;) simply to bold a line without defining a value using a colon (:). This usage renders invalid [[Wikipedia:HTML5]] and creates issues with [[screen reader]]s.}}

Line 1,510:
* '''<nowiki><includeonly></nowiki>: ''' the content '''will render only ''there''''', and '''will not render ''here''''' (like [[invisible ink]] made visible by means of transclusion).
* '''<nowiki><onlyinclude></nowiki>: ''' the content '''will render ''here''''' and '''will render ''there''''', but it will only render ''there'' what is between these tags.
There can be several such section "[[Wikipedia:HTML#Elements|elements]]". Also, they can be nested. All possible renderings are achievable. For example, to render ''there'' one or more sections of the page ''here'' use '''<nowiki><onlyinclude></nowiki>''' tags. To append text ''there'', wrap the addition in '''<nowiki><includeonly></nowiki>''' tags before, within, or after the section. To omit portions of the section, nest '''<nowiki><noinclude></nowiki>''' tags within it.
If a page is transcluded without transclusion markup, it may cause an unintentional [[Help:Category#Putting_pages_in_categories|categorization]]. Any page transcluding it will contain the same category as the original page. Wrap the category markup with '''<nowiki><noinclude></nowiki>''' tags to prevent incorrect categorization.
Line 1,883:
Article editors can normalize the font of characters trailing <code>[<nowiki />[...]]outside</code> a wikilink, which would otherwise adhere to the wikilink font. They can also add line-spacing in the wikitext. Template editors: tag {{tag|nowiki|o}} works only on its source page, not the target; also <code>{{#tag<nowiki />:nowiki | ''content''}}</code>, although it wraps that content in nowiki tags, it also does a [[mw:Manual:Tag extensions#How do I render wikitext in my extension?|pre-save transform]] on that content, which is entirely at odds with the intended purpose of nowiki for templates, subst, signatures, and the pipe-trick.
The two kinds of nowiki operate in different ways to target content, but they both remove meaning (subtract rendering) of wiki markup, then disappear into the background font. Nowiki does nothing toward rendering, but it can add newlines to wikitext (for readability), just like the HTML comment (the preferred method) can. Unlike wiki markup, nowiki does not remove the meaning of ''character entities'', either [[Wikipedia:HTML character entities|HTML]] or MediaWiki [[#Special characters|special ''characters'']].
There is only one meaning for what {{tag|nowiki}} contains, so it needs few examples; but the singular {{tag|nowiki|s}} tag "contains" ''many'' linkage structures, where it is expected between bracketing-pair characters or in the keyword area. So this section has ''many'' examples and few mis-examples.

{{main|Help:HTML in wikitext}}
Many [[Wikipedia:HTML]] tags can be used in wiki markup. You can check your HTML by using [[Help:Markup validation|markup validation]].
