Wikitext markup — making your page look the way you want

Organizing your writing — sections, paragraphs, lists and lines

What it looks like	What you type
Sections and subsections Start sections with header lines Note: Single equal signs give the highest level heading, like the page title; usually projects have the convention not to use them. New section Subsection Sub-subsection Start with a second-level heading (`==`); don't use first-level headings (=). Don't skip levels (for example, second-level followed by fourth-level). A table of contents will automatically be added to an article that has four or more sections. If appropriate, place subsections in an appropriate order. If listing countries, for example, place them in alphabetical order rather than, say, relative to population of OECD countries, or some random order. If you want to keep headings out of the TOC you have to use HTML heading tags and close them without using a slash e.g. <h4>heading too low level to be in the toc of large page<h4>.	== New section == === Subsection === ==== Sub-subsection ====
Newline A single newline has no effect on the layout. But an empty line starts a new paragraph, or ends a list or indented part. (<p> disables this paragraphing until </p> or the end of the section) (in Cologne Blue two newlines and a div tag give just one newline; in the order newline, div tag, newline, the result is two newlines) You can make the wikitext more readable by putting in newlines. You might find this causes future problems — see w:Wikipedia:Don't use line breaks for details. When used in a list, a newline does affect the layout (See Help:List).	A single newline has no effect on the layout. But an empty line starts a new paragraph.
You can break lines without starting a new paragraph. (The HTML tag <br> is sufficient. The system produces the XHTML code <br />.) Please use this sparingly. Close markup between lines; do not start a link or italics or bold on one line and close it on the next.	You can break lines<br> without starting a new paragraph.
Unordered Lists are easy to do: start every line with a star more stars means deeper levels A newline in a list marks the end of the list. Of course you can start again.	* Unordered Lists are easy to do: start every line with a star * more stars means deeper levels A newline in a list marks the end of the list. Of course you can *start again.
Numbered lists are also good very organized easy to follow A newline in a list marks the end of the list. New numbering starts with 1.	# Numbered lists are also good ## very organized ## easy to follow #A newline #in a list marks the end of the list. #New numbering starts #with 1.
You can even do mixed lists and nest them or break lines in lists	* You can even do mixed lists # and nest them #* or break lines<br>in lists
Definition list word definition of the word longer phrase phrase defined	; word : definition of the word ; longer phrase : phrase defined One item per line; a newline can appear before the colon, but using a space before the colon improves parsing.
indenting A colon indents a line or paragraph. A manual newline starts a new paragraph. This is often used for discussion on Talk pages.	: A colon indents a line or paragraph. A manual newline starts a new paragraph.
When there is a need for separating a block of text the blockquote command will indent both margins when needed instead of the left margin only as the colon does. This is useful for (as the name says) inserting blocks of quoted (and cited) text.	<blockquote> The '''blockquote''' command will indent both margins when needed instead of the left margin only as the colon does. </blockquote>
Centered text. Please note the US-English spelling of "center".	<center>Centered text.</center>
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.	A horizontal dividing line: this is above it... ---- ...and this is below it.

Links, URLs

Internal links

General notes:

Enclose the target name in double square brackets — "[[" and "]]"
First letter of target name is automatically capitalized
Spaces are represented as underscores (but don't do underscores yourself)
Links to nonexistent pages are shown in red — Help:Starting a new page tells about creating the page.
When the mouse cursor "hovers" over the link, you see a "hover box" containing... hover over links bellow to see.

Section of page List of cities by country#Morocco List of cities by country#Norway If the section doesn't exist, the link goes to the top of the page. If there are multiple sections by the same name, link to specific ones by adding how many times that header has already appeared (e.g. if there are 3 sections entitled "Example header," and you wish to link to the third one, then use [[#Example section 3]].

Piped link Use a pipe "\|" to create a link label: About Links	*[[Help:Link\|About Links]]

Text formatting — controlling how it looks

What it looks like	What you type
Emphasize (italics), strongly (bold), very strongly (bold italics). (These are double and triple apostrophes, not double quotes.) Note: this can also be applied to links (e.g., Wikipedia).	''Emphasize'', '''strongly''', '''''very strongly'''''. ''[[Wikipedia]]''
You can also write italic and bold. This is useful in mathematical formulas where you need specific font styles rather than emphasis. F = ma (The difference between these two methods is not very important for graphical browsers, so most people ignore it). But it may make a big difference for the visually impaired ;-)	You can also write <i>italic</i> and <b>bold</b>. This is useful in mathematical formulas where you need specific font styles rather than emphasis. :<b>F</b> = <i>m</i><b>a</b>
You can also write in small caps. If the wiki has the templates, this can Template:Bsmbe much simpler to writeTemplate:Esm.	You can also write <span style="font-variant:small-caps"> in small caps</span>. If the wiki has the templates, this can {{bsm}}be much simpler to write{{esm}}.
A typewriter font, sometimes used for `technical terms` and `computer code`.	A typewriter font, sometimes used for <tt>technical terms</tt> and <code>computer code</code>. For semantic reasons, using `<code>` where applicable is preferable to using `<tt>`.
You can use small text for captions.	You can use <small>small text</small> for captions.
You can ~~strike out deleted material~~ and underline new material. You can also mark ~~deleted material~~ and inserted material using logical markup rather than visual markup. When editing regular 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 <strike>strike out deleted material</strike> and <u>underline new material</u>. You can also mark <del>deleted material</del> and <ins>inserted material</ins> using logical markup rather than visual markup.
Subscript: x₂ Superscript: x² or x² Most browsers have an easier time formatting lines with ² than with <sup>2</sup> ε₀ = 8.85 × 10⁻¹² C² / J m. 1 hectare = 1 E4 m²	Subscript: x<sub>2</sub> Superscript: x<sup>2</sup> or x² ε<sub>0</sub> = 8.85 × 10<sup>−12</sup> C² / J m. 1 [[hectare]] = [[1 E4 m&sup2]]

IF a line of plain text starts with a space
 it will be formatted exactly

this is useful for:
 * pasting preformatted text;

 * chemical structures;

WARNING If you make it wide, you force the whole page to be wide and hence less readable. Never start ordinary lines with spaces.

Including another page — transclusion and templates

Changing a transcluded file will change every file that transcludes it.

transclusion: Including the contents of another page into the current page.

This transclusion demo is a little bit of text to be included into any file.

But it isn't a demo ... it's just a line of text.

{{:Help:Transclusion Demo}}

template

A special kind of page designed for transclusion. These pages are found in the Template: namespace Templates can even take parameters. When you edit a page, all the templates used on the page are listed below the edit box.

Template:H:title

{{H:title|hovertext|This is underlined}}
