{{TOC limit}}

 

* Do not use <em>any</em> markup after the final heading markup – this will either break the heading, or will cause the heading to not be included in an edit summary.

 

 

Templates: {{tl|fake heading}} for use in documentation.

* <code><nowiki>__NOTOC__</nowiki></code> disables the TOC entirely.

* {{tl|TOC limit}} can be used to control the depth of subsections included in the TOC. This is useful where the TOC is long and unwieldy.

 

===Line breaks===

 

Line breaks or newlines are used to add whitespace between lines, such as separating paragraphs.

 

===Center text===

{{markup

|<syntaxhighlight lang="html" inline style="border:none; background:transparent;"><div class="center" style="width: auto; margin-left: auto; margin-right: auto;">Centered text</div></syntaxhighlight>

 

===={{Anchor|DL}}Description lists====

 

To list terms and definitions, start a new line with a semicolon (;) followed by the term. Then, type a colon (:) followed by a definition. The format can also be used for other purposes, such as make and models of vehicles, etc.

''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.

===Special characters===

 

====Diacritical marks====

{| class="wikitable"

! What you type

|Τ Υ Φ Χ Ψ Ω

|}

 

====Subscripts and superscripts====

* The [[Wikipedia:Manual of Style (mathematics)#Superscripts and subscripts|Manual of Style]] prefers the {{tag|sub|o}} and {{tag|sup|o}} formats, for example <code>x{{tag|sub|content=1}}</code>. So this should be used under most circumstances.

 

{| class="wikitable"

&epsilon;₀ = 8.85 &times; 10^&minus;12 C&sup2; / J m

{{main|wikipedia:MOS:TEXT#PUA and RTL}}

 

 

===Mathematical characters and formulae===

====Mathematical characters====

 

 

{| class="wikitable"

{{main|Help:Displaying a formula}}

 

 

 

* The {{tl|math}} template [[wikipedia:MOS:MATH#Using_HTML|uses HTML]], and will size-match a serif font, and will also prevent line-wrap. All templates are sensitive to the <code>=</code> sign, so remember to replace <code>=</code> with <code>{{tl|{{=}}}}</code> in template input, or start the input with <code>1=</code>. Use wikimarkup <code><nowiki>''</nowiki></code> and <code><nowiki>'''</nowiki></code> inside the {{tl|math}} template, as well as other [[Wikipedia:Mathematical_symbols|HTML entities]]. The {{tl|math}} template is best for typeset formulas in line with the text.

====Complicated formulae====

 

* A formula displayed on a line by itself should probably be indented by using the colon (:) character.

 

 

==Links and URLs==

 

===Free links===

 

 

 

====Link to another wiki article====

 

* Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).

 

{{markup

|<nowiki>London has [[public transport]].</nowiki>

 

|<nowiki>Link to this article: "[[Help:Wikitext]]" will appear only as bold text.</nowiki>

|-

|

|

|}

 

====Automatically rename links====

 

 

{| class="wikitable"

<code><nowiki>[[kingdom (biology)|]]</nowiki></code>

|

|-

| ''Automatically hide the comma and following text''

| <code><nowiki>[[Seattle, Washington|]]</nowiki></code>

|-

|

<code><nowiki>[[Wikipedia:Village pump|]]</nowiki></code>

|

|-

|

 

* Endings are blended into the link.

* Preferred style is to use this instead of a piped link, if possible.

* Blending can be suppressed by using the [[#Nowiki|{{tag|nowiki|s}}]] tag, which may be desirable in some instances.

|

<code><nowiki>San Francisco also has [[public transport]]ation. Examples include [[bus]]es, [[taxicab]]s, and [[tram]]s.</nowiki></code>

|-

| <code><nowiki>A [[micro-]]second</nowiki></code>

|-

|

<code><nowiki>A [[micro-]]<nowiki />second.</nowiki></code>

|

|}

 

====Link to a section of a page====

 

* Include "| link title" to create a stylish ([[wikipedia:WP:Piping|piped]]) link title.

* If sections have the same title, add a number to link to any but the first. [[#Example section 3]] goes to the third section named "Example section". You can use the pipe and retype the section title to display the text without the # symbol.

 

===Redirects===

 

 

{| class="wikitable" border=1

|}

 

 

*The full page name should be included in double square brackets.

|-

|

|

|}

 

===Link to the same article in another language (interlanguage links)===

{{notice|After the launch of [[Wikipedia:Wikidata|Wikidata]], interlanguage links are now added through it. Links in articles should exist only in special cases, for example when an article in one language has two articles in another language.}}

 

* Interlanguage links are not visible within the formatted article, but instead appear as language links on the sidebar (to the left) under the menu section "languages".

<pre>

===Interwiki link===

 

* Note that interwikimedia links use the internal link style, with double square brackets.

* See also [[Wikipedia:Wikimedia sister projects|Wikimedia sister projects]].

 

 

*Single square brackets indicate an external link. Note the use of a ''space'' (not a pipe |) to separate the URL from the link text in a named link. Square brackets may be used as normal punctuation when not linking to anything – [like this].

:*Use the link button [[File:OOjs UI icon link-ltr.svg]] on the enhanced editing toolbar to encode the link; this tool will add the bracket markup and the linked text, which may not always be desirable.

:*Or manually encode the URL by replacing these characters:

| %20 || %22 || %27 || %2c || %3b || %3c || %3e || %3f || %5b || %5d

|}

 

* See [[Wikipedia:External links]] for style issues, and [[:Category:External link file type templates]] for indicating the file type of an external link with an icon.

<code><nowiki>[http://www.wikipedia.org Wikipedia]</nowiki></code>

 

===Automatic links===

 

Magic links are automatic links for certain unique identifiers that require no markup. They can be used for ISBN numbers, RFC numbers, and PMID numbers.

==Images==

 

See the Wikipedia's [[Wikipedia:Image use policy|image use policy]] for the policy used on Wikipedia.

 

==Columns==

Use {{tl|colbegin}} and {{tl|colend}} to produce columns.

 

==References and citing sources==

 

Making a reference citing a printed or online source can be accomplished by using the {{tag|ref}} tags. Inside these tags details about the reference are added.

==Templates and transcluding pages==

{{main|Wikipedia:Transclusion}}

 

Examples for templates: <nowiki>{{pad|...}}, {{math|...}}, {{as of|...}}, {{edit}}</nowiki>

 

They are specified by putting the template's name in <nowiki>{{double braces}}</nowiki>. Most templates are pages in the [[wikipedia:WP:Template namespace|Template namespace]], but it is possible to transclude mainspace pages (articles) by using <nowiki>{{:colon and double braces}}</nowiki>.

 

They determine whether or not wikitext renders, either in its own article, which we will call "'''here'''", or in another article where it is transcluded, which we will call "'''there'''".

* '''<nowiki><noinclude></nowiki>: ''' the content '''will not be rendered ''there'''''. These tags have no effect ''here''.

* '''<nowiki><onlyinclude></nowiki>: ''' the content '''will render ''here''''' and '''will render ''there''''', but it will only render ''there'' what is between these tags.

 

{{anchor|hovertext}}

Some templates take ''parameters'', as well, which you separate with the pipe character <code>|</code>.

{{anchor|NOWIKI}}

{{redirect|wikipedia:WP:NOWIKI|the essay about the name "Wiki"|Wikipedia:Don't abbreviate "Wikipedia" as "Wiki"!}}

 

In order for the software to interpret wiki markup, its parser first scans the page. When it sees its nowiki tags

:{{tag|nowiki|s}} (escapes the interpretations it is designed to "break"),

it escapes its wikicode, so editors can document its markup ''using'' its markup.

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&nbsp;|&nbsp;''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.

 

 

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.

<nowiki /># Ordered list

|<nowiki>A [[micro-]]second.</nowiki>

|<nowiki>A [[micro-]]<nowiki />second.</nowiki>

|<nowiki>a<nowiki>

 

:{{ ''pagename'' <nowiki />| {{ ''pagename'' }<nowiki />} }}

 

 

====Displaying wikilinks====

 

====Displaying magic words====

 

For input '''parameters''', {{{1}}}, {{{2}}}, just write them out, unless they have a default (which goes behind their pipe):

 

==Invisible text (comments)==

 

It's uncommon{{spaced ndash}}but on occasion acceptable for notes to other editors{{spaced ndash}}to add a hidden comment within the text of an article. These comments are visible only when editing or viewing the source of a page. Most comments should go on the appropriate [[Wikipedia:Talk page|Talk page]]. <!-- This is an example of text that is not visible except in "edit" mode. --> The format is to surround the hidden text with "<code>&lt;!--</code>" and "<code>--&gt;</code>" and may cover several lines, e.g.:

{{main|Help:HTML in wikitext}}
