London has public transport.

• A 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 above is to the URL en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Wikipedia:Canonicalization.

London has [[public transport]].

San Francisco also has public transportation.

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

San Francisco also has
[[public transport|
public transportation]].

San Francisco also has public transportation.

Examples include buses, taxicabs, and streetcars.

• 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 <nowiki></nowiki> tags, which may be desirable in some instances. Example: a microsecond.

San Francisco also has
[[public transport]]ation.

Examples include [[bus]]es,
 [[taxicab]]s, and [[streetcar]]s.

a [[micro]]<nowiki>second
</nowiki>

See the Wikipedia:Manual of Style.

• A link to another namespace.

[[Wikipedia:Manual of Style]].

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.

#and another example is a link to an anchor too, but this one was created using SPAN tag instead of the DIV tag in the previous one.

Italics is a stylish link to a section within another 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.
• Identifiers may be created by attaching an id="..." attribute to almost any HTML element. This doesn't work with legacy browsers.
• Include "| link title" to create a stylish link title.

When adding a comment to a Talk page, you should sign it by adding four tildes to add your user name plus date/time:

Patricia Zhang 13:40, Jan 14, 2007 (UTC)

Three tildes will add just your user name:

Patricia Zhang

and five tildes gives the date/time alone:

13:40, Jan 14, 2007 (UTC)

• The first two both provide a link to your user page.

• 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 United States page, to the History section if it exists.

#REDIRECT [[United States]]

#REDIRECT [[United States#History|United 
States History]] will redirect to the 
[[United States]] page, to the History 
section if it exists 

• Link to a page on the same subject in another language by using a link of the form: [[language code:Title]].

• It does not matter where you put these links while editing as they will always show up in the same place when you save the page, but placement at the end of the edit box is recommended.
• Please see Wikipedia:Interlanguage links and the list of languages and codes.

[[Category:Character sets]]

• To link to a Wikipedia:Category page without putting the article into the category, use an initial colon (:) in the link.

Three ways to link to external (non-wiki) sources:

1. Bare URL: http://www.wikipedia.com/ (bad style)
2. Unnamed link: [1] (only used within article body for footnotes)
3. Named link: Wikipedia

See MetaWikiPedia:Interwiki_map for the list of shortcuts.

• 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" version.
• 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.
• If the "named" version contains a closing square bracket "]", then you must use the HTML special character syntax, i.e. &#93; otherwise the MediaWiki software will prematurely interpret this as the end of the external link.
• There is a class that can be used to remove the arrow image from the external link. It is used in Template:Ref to stop the URL from expanding during printing. It should never be used in the main body of an article. However, there is an exception: wikilinks in Image markup. An example of the markup is as follows:
  • Markup: <span class="plainlinksneverexpand"> [http://www.sysinternals.com/ ntw2k/freeware/winobj.shtml WinObj]</span>
  • Display: WinObj
• See Wikipedia:External links for style issues.

Linking to other wikis:

1. Interwiki link: Wiktionary:Hello
2. Interwiki link without prefix: Hello
3. Named interwiki link: Wiktionary definition of 'Hello'

• All of these forms lead to the URL http://en.wiktionary.org/wiki/Hello
• 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 above).
• See also Wikipedia:How to link to Wikimedia projects.

ISBN 012345678X

ISBN 0-12-345678-X

• 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.

• Alternative text, used when a mouse hovers over the image or when the image is loaded in a text-only browser, or when spoken aloud, is strongly encouraged. See Alternate text for images for help on choosing it.

Floating to the right side of the page using the ''frame'' attribute and a caption:
[[Image:wiki.png|frame|Wikipedia Encyclopedia]]

• The frame tag automatically floats the image right.
• The caption is also used as alternate text.

Floating to the right side of the page using the ''thumb'' attribute and a caption:
[[Image:wiki.png|thumb|Wikipedia Encyclopedia]]

• The thumb tag automatically floats the image right.
• The caption is also used as alternate text.
• An enlarge icon is placed in the lower right corner.

Linking directly to an image
without displaying it:
[[:media:wiki.png|Image of the jigsaw globe logo]]

• To include links to images shown as links instead of drawn on the page, use a "media" link.

A typewriter font for monospace text or for computer code: int main()

• For semantic reasons, using <code> where applicable is preferable to using <tt>.

A typewriter font for <tt>monospace text</tt>
or for computer code: <code>int main()</code>

#include <iostream.h>
int main ()
{
cout << "Hello World!";
return 0;
}

Use <code><pre> Block of Code </pre></code> around the 
block of code.

* The <pre> tags within the codeblock will create formatting 
issues - to solve, display the tags literally with 
&lt;pre&gt;  and  &lt;/pre&gt;

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 strike out deleted material and underline new material.

You can also mark deleted material and inserted material using logical markup. For backwards compatibility better combine this potentially ignored new logical with the old physical markup.

• 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.

You can <s>strike out deleted material</s>
and <u>underline new material</u>.

You can also mark <del>deleted material</del> and
<ins>inserted material</ins> using logical markup.
For backwards compatibility better combine this
potentially ignored new <del>logical</del> with
the old <s><del>physical</del></s> markup.

Suppressing interpretation of markup:
Link → (''to'') the [[Wikipedia FAQ]]

• Used to show literal data that would otherwise have special meaning.
• Escape all wiki markup, including that which looks like HTML tags.
• Does not escape HTML character references.
• To escape HTML character references such as &rarr; use &amp;rarr;

<nowiki>Link &rarr; (''to'') 
the [[Wikipedia FAQ]]</nowiki>

• 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.

Ordinary text should use wiki markup for emphasis, and should not use <i> or <b>. However, mathematical formulas often use italics, and sometimes use bold, for reasons unrelated to emphasis. Complex formulas should use <math> markup, and simple formulas may use <math>; or <i> and <b>; or '' and '''. According to WikiProject Mathematics, wiki markup is preferred over HTML markup like <i> and <b>.

<math>\,\! \sin x + \ln y</math>
sin''x'' + ln''y''

<math>\mathbf{x} = 0</math>
'''x''' = 0

Spacing in simple math formulas:
Obviously, x² ≥ 0 is true when x is a real number.

• To space things out without allowing line breaks to interrupt the formula, use non-breaking spaces: &nbsp;.

Obviously, ''x''² ≥ 0 is true when ''x'' is a real number.

Complicated formulas:

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

: <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>
