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	== 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 Help:Don't use line breaks for details.	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 />.)	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
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.
Centered text.	<center>Centered text.</center>
A horizontal dividing line: above and below. If you don't use a section header, you don't get a TOC entry.	A horizontal dividing line: above ---- and below.

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 -- DCCWiki User's Guide: Starting a new page tells about creating the page.
When the mouse cursor "hovers" over the link, you see a "hover box" containing...

Section of page Introduction_to_DCC#FreeDCC. Introduction_to_DCC#Sealand. 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]].

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.)	''Emphasize'', '''strongly''', '''''very strongly'''''.
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).	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`.	A typewriter font, sometimes used for <tt>technical terms</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 <strike>strike out deleted material</strike> and <u>underline new material</u>.
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

Spacing things out -- spaces and tables

Using non-breaking spaces

x² ≥ 0 true.

<i>x</i><sup>2</sup>&nbsp;
&nbsp;&ge;
&nbsp;&nbsp;0 true.

Using Wikitext piped tables

x²		≥0	true.
a		b

See templates Template:hs1, Template:hs, and Template:vs for more examples

{||-
|<i>x</i><sup>2</sup> 
| width=20px | || width=20px | ≥0 || true.
|-
| a || || b
|}

Input boxes

The inputbox extension is a DCCWiki extension by Erik Möller to add predefined HTML forms to wiki pages. It was originally created for the purpose of adding a Create an article box.

General syntax

Inputboxes are constructed like this:

 <inputbox>
 type=box type
 parameter1=value
 parameter2=value
 </inputbox>

The type parameter is mandatory. All other parameters are optional.

Box types

Type	Description	Example
type=search	Generates a search box with a width of 50 characters. The button labels can be specified, see below; the defaults are MediaWiki:Tryexact and MediaWiki:Searchfulltext. The text field specifies the search criteria.
type=create	Allows creating a new page. Note especially the preload= and editintro= options below. The button label can be specified, see below; the default is MediaWiki:Createarticle. The text field specifies which page is to be edited.
type=comment	Add one or more sections to an existing page, or create a page, with an edit summary that is automatically the same as the (first) new section header. The button label can be specified, see below; the default is MediaWiki:Postcomment; note that this message is also used in the sidebar of the old "Standard" skin. The text field specifies which page is to be edited.

Parameters

Parameter Scope	Description	Example
bgcolor= All types	Sets the table background color (HTML color values). Do not use quotes.	<inputbox> type=search bgcolor=#eeeeff </inputbox> produces:
width= All types	Sets the width of the inputbox in characters.	<inputbox> type=create width=6 </inputbox> produces:
default= All types	Default text to put in the inputbox.	<inputbox> type=comment default=User talk:Eloquence </inputbox> produces:
preload= comment, create	The text of the page under this title will be loaded into the blank editbox when a new page is created. Enter the title of a non-existent page in the example inputbox, and click "Create" to test this effect.	<inputbox> type=create preload=Template:Standard content for new page </inputbox> produces:
editintro= comment, create	The text of the page under this title will be added, as instructions, before the submission form for new pages or comments. Enter the title of a non-existent page in the example inputbox, and click "Create" to test this effect.	<inputbox> type=create editintro=Template:Instructions </inputbox> produces:
buttonlabel= All types	This label will be used for the main button of the form.	<inputbox> type=comment buttonlabel=Add new rumor </inputbox> produces:
searchbuttonlabel= search	This label will be used for the "Search full text" button of the search form.	<inputbox> type=search searchbuttonlabel=Dig deeper </inputbox> produces:

Applying create to an existing page simply gives the edit page. In that case editintro and preload are ignored.

Variables, parameters, and templates are not allowed in values of parameters of inputbox; see Template talk:Inputbox demo.

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.

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.
