Help:Wikitext

A video about wikicode and how to use it.

Wiki markup is the syntax and keywords used by the MediaWiki software to format a page. To learn how to see this markup and to save an edit, see: Help:Editing.

Layout

Sections

Section headings

Further information: Help:Section

Use headings to split articles into sections. Put a heading on a separate line. A level-two heading ("==") is the highest level editors use in an article.

Horizontal line Separating with a horizontal dividing line: this is above it... ...and this is below it. If you don't use a section header, you don't get a TOC entry.

Table of contents

When a page has at least four headings, a table of contents (TOC) will appear in front of the first header (after the lead). Putting __TOC__ anywhere forces the TOC to appear at that point (instead of just before the first heading). Putting __NOTOC__ anywhere forces the TOC to disappear. See also Compact TOC for alphabet and year headings.

Line breaks

• You can make the wikitext more readable by putting in newlines, but see Wikipedia:Don't use line breaks for possible problems.
• To break lines use the <br /> element. The HTML tag <br> will be converted to the XHTML <br /> tag by HTML Tidy in most instances. The <br> tag is not converted when used in editnotices or in the MediaWiki namespace — it will render invalid XHTML and will break tools such as Twinkle.
• Please use these sparingly.
• Close markup between lines; do not start a link or italics or bold on one line and close it on the next.
• When used in a list, a newline does affect the layout (see Help:List).

What you type	What it looks like
A single newline has no effect on the layout. But an empty line starts a new paragraph, or ends a list or an indented part.	A single newline has no effect on the layout. But an empty line starts a new paragraph, or ends a list or an indented part.

Retaining newlines and spaces

The MediaWiki software suppresses single newlines and converts lines starting with a space to preformatted text in a dashed box. HTML suppresses multiple spaces. It is often desirable to retain these elements for poems, lyrics, mottoes, oaths and the like. The Poem extension adds HTML-like <poem>...</poem> tags to maintain newlines and spaces. These tags may be used inside other tags such as <blockquote>...</blockquote>. CSS styles may be applied to this tag, e.g.: <poem style="margin-left:2em;">.

Format

Text formatting

Description	What you type	What it looks like
Italics, bold, small capital letters.

To italicize text, just put 2 apostrophes on each side. 3 apostrophes will bold the text 5 apostrophes for bold italics For text as small caps, that uses a template.
Syntax highlighting for source code. Computer code has colored text and more stringent formatting. For example, to define a function: int m2(), with highlights.	<syntaxhighlight lang="cpp"> #include <iostream> int m2 (int ax, char *p_ax) { std::cout <<"Hello World!"; return 0; }</syntaxhighlight>	#include <iostream> int m2 (int ax, char *p_ax) { std::cout <<"Hello World!"; return 0; }
Small text.	Use <small>small text</small> if needed. A span tag can set text font-size as being <span style="font-size:87%">87% of prior size</span>, to match an image caption.	Use small text if needed. A span tag can set text font-size as being 87% of prior size, to match an image caption.
Big text.	Better not use <big>big text</big>, unless <small> it's <big>within</big> small</small> text.	Better not use big text, unless it's within small text.
You can include a non-breaking space (sometimes called non-printing character) where you require two words to always appear together on the same line, such as Mr. Smith or 400 km/h, using &nbsp; in place of a regular space between the two "words" that need to behave as a single word (never be separated on different lines).	Mr.&nbsp;Smith or 400&nbsp;km/h.	Mr. Smith or 400 km/h.
Extra spacing within text can best be achieved using the pad template.	Mary {{pad|4em}} had a little lamb.	Mary   had a little lamb.
Typewriter font. (Does also work beyond the end of a paragraph.)	<tt>arrow &rarr;</tt> <tt>''italics'', '''bold'''</tt> <tt><nowiki>[[link]] New paragraph </tt>started here.	arrow → italics, bold link New paragraph started here.

Subscripts and superscripts

• The Manual of Style prefers the x₁ format.
• The latter methods of sub/superscripting cannot be used in the most general context, as they rely on Unicode support which may not be present on all users' machines. For the 1-2-3 superscripts, it is nevertheless preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

Mathematical formulae

Main page: Help:Displaying a formula

• Formulae that include mathematical letters, like x, and operators like × should not use the plain letter x. See math font formatting. For a comprehensive set of symbols, and comparison between <math> tags and the {{math}} template see section TeX vs HTML.

• The <math> tag typesets using LaTeX markup, which may render as an image or as HTML, depending on environmental settings. The <math> tag is best for the complex formula on its own line in an image format. If you use this tag to put a formula in the line with text, put it in the {{nowrap}} template.

• The {{math}} template uses HTML, and will size-match a serif font, and will also prevent line-wrap. All templates are sensitive to the = sign, so remember to replace = with {{=}} in template input. Use wikimarkup '' and ''' inside the {{math}} template, as well other HTML entities. The {{math}} template is best for typeset formulas in line with the text.

Markup	Renders as
<math>2x \times 4y \div 6z + 8 - \frac {y}{z^2} = 0</math> {{crlf|}} {{math|2x &times; 4y &divide; 6z + 8 &minus; {{Fraction |y|z<sup>2</sup>}} {{=}} 0}} <math>\sin 2\pi x + \ln e\,\!</math> <math>\sin 2\pi x + \ln e</math> {{math|sin 2&pi;''x'' + ln ''e''}}	$2x\times 4y\div 6z+8-{\frac {y}{z^{2}}}=0$ 2x × 4y ÷ 6z + 8 − y⁄z2 = 0 $\sin 2\pi x+\ln e\,\!$ $\sin 2\pi x+\ln e$ sin 2πx + ln e

Spacing in simple math formulae

• Using   to prevent linebreak is not needed; the {{math}} template will prevent line breaks anyway; you can use <br/> if you need an explicit line break inside a formula.

What you type	What it looks like
It follows that {{math |''x''<sup>2</sup> &ge; 0}} is true when {{math|<VAR>x</VAR>}} is a real number.	It follows that x2 ≥ 0 is true when x is a real number.

Complicated formulae

• See Help:Displaying a formula for how to use <math>.
• A formula displayed on a line by itself should probably be indented by using the colon (:) character.

What you type	What it looks like
: <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>	$\sum _{n=0}^{\infty }{\frac {x^{n}}{n!}}$

Links and URLs

Free links

In Wikipedia and some other wikis, free links are used in wikitext markup to produce internal links between pages, as opposed to the concept of CamelCase for the same purpose, which was used in the early days of Wikipedia, see CamelCase and Wikipedia.

In Wikipedia's markup language, you create free links by putting double square brackets around text designating the title of the page you want to link to. Thus, [[Texas]] will be rendered as Texas. Optionally, you can use a vertical bar (|) to customize the link title. For example, typing [[Texas|Lone Star state]] will produce Lone Star state, a link that is displayed as "Lone Star state" but in fact links to Texas.

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).
• Thus the link below is to the URL en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Canonicalization.
• A red link is a page that doesn't exist yet; it can be created by clicking on the link.
• A link to its own page will appear only as bold text.

What you type	What it looks like
London has [[public transport]].	London has public transport.
Link to this own article: "[[Help:Wiki markup]]" will appear only as bold text.	Link to this own article: "Help:Wiki markup" will appear only as bold text.

Renamed link

• Same target, different name.
• The target ("piped") text must be placed first, then the text to be displayed second.

What you type	What it looks like
New York also has [[public transport|public transportation]].	New York also has public transportation.

Automatically rename links

• Simply typing the pipe character (|) after a link will automatically rename the link in certain circumstances. The next time you open the edit box you will see the expanded piped link. When previewing your edits, you will not see the expanded form until you press Save and Edit again. The same applies to links to sections within the same page.
• See Pipe trick for details.

Description	What you type	What it looks like
Automatically hide stuff in parentheses	[[kingdom (biology)|]]	kingdom

Or both	[[Wikipedia:Manual of Style (headings)|]]	Manual of Style
But this doesn't work for section links	[[Wikipedia:Manual of Style#Links|]]	[[Wikipedia:Manual of Style#Links|]]

Blend link

• Endings are blended into the link.
  • Exception: a trailing apostrophe (') and any characters following the apostrophe are not blended.
• Preferred style is to use this instead of a piped link, if possible.
• Blending can be suppressed by using the <nowiki /> tag, which may be desirable in some instances.

Description	What you type	What it looks like
Blending active.	San Francisco also has [[public transport]]ation. Examples include [[bus]]es, [[taxicab]]s, and [[tram]]s.	San Francisco also has public transportation. Examples include buses, taxicabs, and trams.
Blending suppressed.	A [[micro-]]<nowiki />second.	A micro-second.

Link to a section of a page

• The part after the number sign (#) must match a section heading on the page. Matches must be exact in terms of spelling, case, and punctuation. Links to non-existent sections are not broken; they are treated as links to the top of the page.
• Include "| link title" to create a stylish (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.

What you type	What it looks like
[[Wikipedia:Manual of Style#Italics]] is a link to a section within another page.	Wikipedia:Manual of Style#Italics is a link to a section within another page.
[[#Links and URLs]] is a link to another section on the current page. [[#Links and URLs|Links and URLs]] is a link to the same section without showing the # symbol.	#Links and URLs is a link to another section on the current page. Links and URLs is a link to the same section without showing the # symbol.
[[Wikipedia:Manual of Style#Italics|Italics]] is a piped link to a section within another page.	Italics is a piped link to a section within another page.

Create page link

• To create a new page:
  1. Create a link to it on some other (related) page.
  2. Save that page.
  3. Click on the link you just made. The new page will open for editing.
• For more information, see starting an article and check out Wikipedia's naming conventions.
• Please do not create a new article without linking to it from at least one other article.

Redirects

• Redirect one article title to another by placing a directive like the one shown to the right on the first line of the article (such as at a page titled "USA").
• It is possible to redirect to a section. For example, a redirect to United States#History will redirect to the History section of the United States page, if it exists.

Description	What you type
Redirect to an article.	#REDIRECT [[United States]]

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

• To link to a corresponding page in another language, use the form: [[language code:Foreign Title]].
• It is recommended interlanguage links be placed at the very end of the article.
• 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".
• For further help, please see Interlanguage links and the Complete list of language wikis available.

NOTE: To create an inline link (a clickable link within the text) to any foreign language article, see Inline interlanguage links and consider the usage notes.

Description	What you type
Link from English article "Plankton" to the Spanish article "Plancton". "es" is the language code for "español" (the Spanish language).	[[es:Plancton]]
Other examples: German (de for Deutsch), Russian (ru), and simple English (simple).	[[de:Plankton]] [[ru:Планктон]] [[simple:Plankton]]

Interwiki link

• Link to any page on other Wikimedia wikis.
• Note that interwiki links use the internal link style.
• See MetaWikiPedia:Interwiki_map for the list of shortcuts; if the site you want to link to is not on the list, use an external link (see below)
• See also Wikimedia sister projects.

Description	What you type	What it looks like

Simple link. Without prefix. Named link.	[[Wiktionary:fr:bonjour]] [[Wiktionary:fr:bonjour|]] [[Wiktionary:fr:bonjour|bonjour]]	Wiktionary:fr:bonjour fr:bonjour bonjour

Categories

• To put an article in a category, place a link like the one to the right anywhere in the article. As with interlanguage links, placing these links at the end of the edit box is recommended.
• To link to a category page without putting the article into the category, use a colon prefix (":Category") in the link.

Description	What you type	What it looks like
Categorize an article.	[[Category:Character sets]]
Link to a category.	[[:Category:Character sets]]	Category:Character sets
Without prefix.	[[:Category:Character sets|]]	Character sets

External links

• Square brackets indicate an external link. Note the use of a space (not a pipe) to separate the URL from the link text in the "named" link. Square brackets may be used as normal when not linking to anything — [like this].
• URLs must begin with a supported URI scheme: http:// and https:// will be supported by all browsers; irc://, ircs://, ftp://, news://, mailto: and gopher:// will require a plugin or an external application. IPv6 addresses in URLs are currently not supported.
• URLs containing certain characters will display and link incorrectly unless those characters are encoded. For example, a space must be replaced by %20. Encoding can be achieved by:

• Use the link button 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:

sp	"	,	'	;	<	>	?	[	]
%20	%22	%2c	%3a	%3b	%3c	%3e	%3f	%5b	%5d

• See External links for style issues, and External link file type templates for indicating the file type of an external link with an icon.

Automatic links

Book sources

• Link to books using their ISBN. This is preferred to linking to a specific online bookstore, because it gives the reader a choice of vendors. However, if one bookstore or online service provides additional free information, such as table of contents or excerpts from the text, then a link to that source will aid the user and is recommended. ISBN links do not need any extra markup, provided you use one of the indicated formats.
• To create a link to Book Sources using alternative text (e.g. the book's title), use the internal link style with the appropriate namespace.

What you type	What it looks like

Pronunciation aids

It is often desirable to provide an aid to pronunciation for a word. The IPAc-en and Respell templates can be of assistance.

What you type	What it looks like

Tables

There are two ways to build tables:

• In special wiki-markup (see Table).
• Using HTML elements: <table>, <tr>, <td> or <th>.

See also When tables are appropriate.

References and citing sources

Main page: Wikipedia:Citing_sources

See also: APA style, Chicago style, Harvard style, and MLA style

Making a reference citing a printed or online source can be accomplished by using the ref tag. Inside the reference tag details about the reference are added. You can add additional attributes to add detail about the source and reference, a pipe (|) precedes each reference, each attribute goes inside the cite portion of the tag.

Templates and transcluding pages

Main page: Wikipedia:Transclusion

See also: Help:Template § Noinclude, includeonly, and onlyinclude

Examples for templates: {{pad|...}}, {{math|...}}, {{as of|...}}, {{edit}}

Templates are segments of wiki markup that are meant to be copied automatically ("transcluded") into a page. You add them by putting the template's name in {{double braces}}. It is also possible to transclude other pages by using {{:colon and double braces}}.

There are three pairs of tags that can be used in wikitext to control how transclusion affects parts of a template or article. 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".

• <noinclude>: the content will not be rendered there. These tags have no effect here.
• <includeonly>: the content will render only there, and will not render here (like invisible ink made visible by means of transclusion).
• <onlyinclude>: 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 "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 <onlyinclude> tags. To append text there, wrap the addition in <includeonly> tags above, within, or below the section. To omit portions of the section, nest <noinclude> tags within it.

If a page is transcluded without transclusion markup, it may cause an unintentional categorization. Any page transcluding it will contain the same category as the original page. Wrap the category markup with <noinclude> tags to prevent incorrect categorization.

Some templates take parameters, as well, which you separate with the pipe character.

Talk and project pages

Signing comments

• The character tilde (~) is used when adding a comment to a Talk page.
• Your username provides a link to your user page.

Description	What you type	What it looks like
You should sign your comments by appending four tildes to the comment, which adds your user name plus date/time.	~~~~	Username (talk) 09:05, 12 July 2024 (UTC)
Adding three tildes will add just your user name.	~~~	Username (talk)
Adding five tildes gives the date/time alone.	~~~~~	09:05, 12 July 2024 (UTC)

What links here and related changes

What you type	What it looks like
[[Special:WhatLinksHere/aaa]]	Special:WhatLinksHere/aaa
[[Special:RecentChangesLinked/aaa]]	Special:RecentChangesLinked/aaa

Linking to old revisions of pages, diffs, and specific history pages

• External link function is used for these.
• Open an old revision or diff and copy the URL from the address bar, pasting it where you want it.

What you type	What it looks like
[http://en.wikipedia.org/w/index.php?title=Help:Wiki_markup&diff=330350877&oldid=330349143 previous edit]	previous edit

User edits

• Link to a user's Contributions page.

Description	What you type	What it looks like
Username (registered users).	[[Special:Contributions/UserName]]	Special:Contributions/UserName
IP address (unregistered users).	[[Special:Contributions/192.0.2.0]]	Special:Contributions/192.0.2.0

Coloring text

What you type	What it looks like
I will change the color in {{color|red|the middle part of}} this sentence.	I will change the color in the middle part of this sentence.

Show deleted or inserted text

• When editing regular Wikipedia articles, just make your changes and do not mark them up in any special way.
• When editing your own previous remarks in talk pages, it is sometimes appropriate to mark up deleted or inserted material.
• For striking out material, the <code><s></s></code> markup is a less semantic element than <code><del></del></code>.

What you type	What it looks like
You can <del>strike out deleted material</del> and <ins>underline new material</ins>. {{du|Double underlining}} is also possible.	You can strike out deleted material and underline new material. Double underlining is also possible.
Alternative markup: You can <s>strike out deleted material</s> and <u>underline new material</u>.	Alternative markup: You can strike out deleted material and underline new material.

Notes

The <s> element is listed as deprecated in HTML 4 but is used in HTML 5.

Limiting formatting / escaping wiki markup

A few different kinds of formatting will tell the wiki to display things as you typed them — what you see is what you get!

What you type	What it looks like
'''&<nowiki&> tag:''' <nowiki> The nowiki tag ignores [[wiki]] ''markup''. It reformats text by removing newlines and multiple spaces. It still interprets special characters: &rarr; </nowiki>	<nowiki> tag: The nowiki tag ignores [[wiki]] ''markup''. It reformats text by removing newlines and multiple spaces. It still interprets special characters: →
'''&<pre&> tag:''' <pre> The <pre> tag ignores [[wiki]] ''markup'' as does the <nowiki> tag. Additionally, <pre> displays in a mono-spaced font, but does not reformat text spaces. It still interprets special characters: &rarr; </pre>	<pre> tag: The <pre> tag ignores [[wiki]] ''markup'' as does the <nowiki> tag. Additionally, <pre> displays in a mono-spaced font, but does not reformat text spaces. It still interprets special characters: →

Nowiki

In some instances, it is not desirable to parse markup nor to format it using <pre>. <nowiki> is a parser tag that causes the included content to not be parsed as wikimarkup, except for HTML entities. It is very useful in documentation to display markup.

Markup	Renders as
<nowiki>{{cite book}}</nowiki>	{{cite book}}

A singular <nowiki /> can be used to break wikimarkup.

• Markup such as *, #, ; and : only and always take effect at the beginning of a line. A <nowiki /> before the markup will cause the characters to not parse as markup.
• An internal link immediately followed by characters are blended to form a single link. Where this is not desired, add a <nowiki /> after the link.

<nowiki> examples

Markup	Renders as
* Unordered list	Unordered list
<nowiki />* Unordered list	* Unordered list
A [[micro-]]second.	A micro-second.
A [[micro-]]<nowiki />second.	A micro-second.
'<nowiki />'We don't want italics.'<nowiki />'	''We don't want italics.''
[[<nowiki />example<nowiki />]]	[[example]]

HTML entities

<nowiki> parses HTML entities. If you want to escape this, replace & with &.

Markup	Renders as
<nowiki>&amp;</nowiki>	&
<nowiki>&lt;</nowiki>	<
<nowiki>&amp;amp;</nowiki>	&amp;
<nowiki>&amp;lt;</nowiki>	&lt;

Use in templates

When used in a template, <nowiki> simply does not work as you may expect.

• Including <nowiki> immediately acts upon the enclosed markup. Attempting to escape or transclude the brackets causes <nowiki /> to not work at all.
• Using #tag:nowiki works, but has major limitations:
  • Templates, parameters, parser functions, and parser magic such as signatures are parsed, not nowikied.
  • Included <ref> tags will expose the strip markers.

Markup	Renders as
<nowiki>{{tl|cite book}}</nowiki>	{{tl|cite book}}
{{#tag:nowiki|{{tl|cite book}}}}	<span class="nowrap">{{</span>[[Template:cite book|cite book]]<span class="nowrap">}}</span>
{{#tag:nowiki|<ref>text</ref>}} {{reflist}}

Pre

<pre> is a parser tag that emulates the HTML <pre> tag. It defines preformatted text that is displayed in a fixed-width font and is enclosed in a dashed box. HTML and wiki markups are escaped and spaces and line breaks are preserved, but HTML entities are parsed.

<pre> examples

Markup	Renders as
<pre><!--Comment--> [[wiki]] markup &amp;</pre>	<!--Comment--> [[wiki]] markup &

<pre> formatted text does not wrap, thus text may extend past the browser window:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. 

To resolve this, <pre> may use CSS styling to add wrapping or a horizontal scrollbar:

• <pre style="overflow:auto; width:auto; white-space:-moz-pre-wrap; white-space:-pre-wrap; white-space:-o-pre-wrap; white-space:pre-wrap; word-wrap:break-word;">
• <pre style="scroll white-space:-moz-pre-wrap; white-space:-pre-wrap; white-space:-o-pre-wrap; white-space:pre-wrap; word-wrap:break-word;">

Since this involves quite a bit of markup, the template {{pre2}} is useful.

Invisible text (comments)

See also: Help:Hidden text

It's uncommon — but on occasion acceptable for notes to other editors — to add a hidden comment within the text of an article. These comments are only visible when editing or viewing the source of a page. Most comments should go on the appropriate Talk page. The format is to surround the hidden text with "<!--" and "-->" and may cover several lines, e.g.:

<!-- An example of hidden comments
 This won't be visible except in "edit" mode. -->

NUMBEROFARTICLES is the number of pages in the main namespace which contain a link and are not a redirect, in other words number of articles, stubs containing a link, and disambiguation pages.

CURRENTMONTHNAMEGEN is the genitive (possessive) grammatical form of the month name, as used in some languages; CURRENTMONTHNAME is the nominative (subject) form, as usually seen in English.

In languages where it makes a difference, you can use constructs like {{grammar:case|word}} to convert a word from the nominative case to some other case. For example, {{grammar:genitive|{{CURRENTMONTHNAME}}}} means the same as {{CURRENTMONTHNAMEGEN}}.

HTML

Many HTML tags can be used in wiki markup. You can check your HTML by using markup validation.
