Format

Text formatting

What it looks like	What you type
You can italicize text by putting 2 apostrophes on each side. 3 apostrophes will bold the text. 5 apostrophes will bold and italicize the text. You can also display text with small caps, but you have to use a template. A semicolon at the start of a line bolds the entire line. Sometimes, it functions as a section header (see above).	You can ''italicize text'' by putting 2 apostrophes on each side. 3 apostrophes will '''bold the text'''. 5 apostrophes will '''''bold and italicize the text'''''. You can also display text with {{Smallcaps\|small caps}}, but you have to use a [[Help:Template\|template]]. ;A semicolon at the start of a line bolds the entire line. Sometimes, it functions as a section header (see [[Help:Wiki markup#Sections\|above]]).
Syntax highlighting for source code. Computer code has a colored background and more stringent formatting. Suppose we want to define `int main()`: #include <iostream> int main ( int argc, char **argv ) { std::cout << "Hello World!"; return 0; }	Computer code has a colored background and more stringent formatting. Suppose we want to define <code>int main()</code>: <syntaxhighlight lang="cpp">#include <iostream> int main ( int argc, char **argv ) { std::cout << "Hello World!"; return 0; }</syntaxhighlight>
You can use small text for captions.	You can use <small>small text</small> for captions.
Better stay away from big text, unless it's within small text.	Better stay away from <big>big text</big>, unless <small> it's <big>within</big> small</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 ` ` 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. Smith or 400 km/h.
Extra spacing within text can best be achieved using the pad template: Mary had a little lamb.	Mary {{pad\|4em}} had a little lamb.
Typewriter font (does also work beyond the end of a paragraph): `arrow →` `italics` `link` `New paragraph` started here.	<tt>arrow →</tt> <tt>''italics''</tt> <tt>[[link]] New paragraph </tt>started here.

Subscripts and superscripts

The Manual of Style prefers the x<sub>1</sub> 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

Formulae that include mathematical letters, like $x$ , and operators like "×" should not use the plain letter "x". See the Font formatting section of the manual of style for mathematics. For a comprehensive set of symbols, and comparison between <math> tags and the {{math}} template see section TeX vs HTML in Displaying a formula.

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 wikitext '' and ''' inside the ${{{1}}}$ template, as well other HTML entities. The {{math}} template is best for typeset formulas in line with the text.

What it looks like (in comparison)

What you type (in comparison)

$2 x \times 4 y \div 6 z + 8 - \frac{y}{z^{2}} = 0$
$2x \times 4y \div 6z + 8 - y⁄z 2 = 0$

$\sin 2 π x + \ln e$
$\sin 2 π x + \ln e$
$sin 2π x + ln e$

<math> 2x \times 4y \div 6z + 8 - \frac {y}{z^2} = 0 </math>

<math>\sin 2\pi x + \ln e</math>
{{math|sin 2&pi;''x'' + 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 it looks like	What you type
It follows that $x 2 \geq 0$ is true when $x$ is a real number.	It follows that {{math\|''x''<sup>2</sup> ≥ 0}} is true when {{math\|<VAR>x</VAR>}} 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 it looks like	What you type
$\sum_{n = 0}^{\infty} \frac{x^{n}}{n!}$	: <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>

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 it looks like	What you type
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 it looks like	What you type
New York also has public transportation.	`New York also has [[public transport\|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 it looks like	What you type
Automatically hide stuff in parentheses.	kingdom	`[[kingdom (biology)\|]].`
Automatically hide namespace.	Village pump	`[[Wikipedia:Village pump\|]].`
Or both.	Manual of Style	`[[Wikipedia:Manual of Style (headings)\|]]`
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 <nowiki></nowiki> tags, which may be desirable in some instances.

Description	What it looks like	What you type
Blending active.	San Francisco also has public transportation. Examples include buses, taxicabs, and trams.	`San Francisco also has [[public transport]]ation. Examples include [[bus]]es, [[taxicab]]s, and [[tram]]s.`
Blending suppressed.	A micro-second.	`A [[micro-]]<nowiki></nowiki>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 it looks like	What you type
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 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\|Links and URLs]] is a link to the same section without showing the # symbol.`
Italics is a piped link to a section within another page.	`[[Wikipedia:Manual of Style#Italics\|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.

Description	What it looks like	What you type
Links to pages that don’t exist yet look red.	The article about cardboard sandwiches doesn't exist yet.	`The article about [[cardboard sandwiches]] doesn't exist yet.`

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]]`
Redirect to a section.	`#REDIRECT [[United States#History]]`

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

To link to a page on the same subject in another language, use the form: [[language code: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".
Please see Interlanguage links and the Complete list of language wikis available.

NOTE: To create an inline link (a clickable link within the text), see Inline interlanguage links.

Description	What you type
Link to the German version of "Plankton". "de" is the language-code for "Deutsch" (the German language).	`[[de:Plankton]]`
Other examples.	`[[de:Plankton]] [[es:Plancton]] [[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 it looks like	What you type

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

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].
In the URL, all symbols must be among:
A-Z a-z 0-9 . _ \ / ~ % - + & # ? ! = ( ) @
If a URL contains a character not in this list, it should be encoded by using a percent sign (%) followed by the hex code of the character, which can be found in the table of ASCII printable characters. For example, the caret character (^) would be encoded in a URL as %5E, and square brackets as %5B and %5D.
If the "named" version contains a closing square bracket "]", then you must use the HTML special character syntax, i.e. ] otherwise the MediaWiki software will prematurely interpret this as the end of the external link. In certain cases, the open square bracket must be written as [.
See External links for style issues.

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 it looks like	What you type
ISBN 012345678X	`ISBN 012345678X`
ISBN 0-12-345678-X	`ISBN 0-12-345678-X`
Link to a book using alternative text, such as its title.	`[[Special:BookSources/0670037818\|alternative text, such as its title]]`

RFC number

Link to Internet Engineering Task Force Request for Comments (RFCs).

What it looks like	What you type
Text mentioning an RFC number anywhere, e.g. RFC 4321.	`Text mentioning an RFC number anywhere, e.g. RFC 4321.`

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 it looks like	What you type
Konjac (Page Module:IPA/styles.css has no content.English: /ˈkoʊnjæk/)	`'''Konjac''' ({{IPAc-en\|lang\|pron\|ˈ\|k\|oʊ\|n\|j\|æ\|k}})`

Using wiki markup to make a table in which to place a vertical column of images (this helps edit links match headers, especially in Firefox browsers):	Example: {\| align=right \|- \| Place images here \|}

See the Wikipedia's image use policy as a guideline used on Wikipedia.

For further help on images, including some more versatile abilities, see the picture tutorial.

Tables

There are two ways to build tables:

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

References and citing sources

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.

What it's for	What you type
For creating the reference	<ref name="name for reference">Use a closing tag</ref>
When you cite a book	{{cite book}}
To cite a web source	{{cite web}}

Templates and transcluding pages

Template:See also

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.

What it looks like	What you type
This text comes from the page named Template:Transclusion Demo. It has been transcluded into this page.	{{Transclusion demo}}
This transclusion demo is a little bit of text from the page Help:Transclusion Demo to be included into any file.	{{Help:Transclusion Demo}}
This template takes two parameters, and creates underlined text with a hover box for many modern browsers supporting CSS: Hover your mouse over this text Go to this page to see the H:title template itself: {{H:title}}	This template takes two parameters, and creates underlined text with a hover box for many modern browsers supporting CSS: {{H:title\|This is the hover text\| Hover your mouse over this text}} Go to this page to see the H:title template itself: {{tl\|H:title}}

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 it looks like	What you type
You should sign your comments by appending four tildes to the comment, which adds your user name plus date/time.	Username (talk) 16:46, 21 December 2024 (UTC)	`~~~~`
Adding three tildes will add just your user name.	Username (talk)	`~~~`
Adding five tildes gives the date/time alone.	16:46, 21 December 2024 (UTC)	`~~~~~`

What links here and Related changes

What it looks like	What you type
Special:WhatLinksHere/Help:Wiki markup	`[[Special:WhatLinksHere/Help:Wiki markup]]`
Special:RecentChangesLinked/Help:Wiki markup	`[[Special:RecentChangesLinked/Help:Wiki markup]]`

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

User edits

Link to a user's Contributions page.

Description	What it looks like	What you type
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 it looks like	What you type
I will change the color in the middle part of this sentence.	`I will change the color in {{color\|red\| 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 <s></s> markup is an alternative to <del></del>.

What it looks like	What you type
You can ~~strike out deleted material~~ and underline new material. Double underlining is also possible.	`You can <del>strike out deleted material</del> and <ins>underline new material</ins>. {{du\|Double underlining}} is also possible.`

Notes: The <s> tags are listed as deprecated in HTML 4 but are 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 it looks like	What you type

Invisible text (comments)

Template:See also 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 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}}.
