Wiki Markup

In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.

You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the Sandbox.


Sections, paragraphs, lists and lines

What it looks like What you type
Start your sections with header lines: New section Subsection Sub-subsection


== New section ==

=== Subsection ===

==== Sub-subsection ====
New line: A single newline has no effect on the layout. But an empty line starts a new paragraph. (

disables this paragraphing until

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)


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.

Sufficient as wikitext code is <br>, the XHTML code <br /> is not needed, the system produces this code.

You can break lines
without starting a new paragraph.
* 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.

A manual newline starts a new paragraph.
IF a line of plain text starts with a space THEN
  it will be formatted exactly
    as typed;
  in a fixed-width font;
  lines won't wrap;
ENDIF
this is useful for:
  * pasting preformatted text;
  * algorithm descriptions;
  * program source code
  * ASCII art;
  * 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.

Centered text.
Centered text.
A horizontal dividing line: above ---- and below. (However, in most cases a section header is more useful. The horizontal dividing line should only be used if what follows is logically part of the same section; otherwise that part would be hidden in the TOC.)

Summarizing the effect of a single newline: no effect in general, but it ends a list item or indented part; thus changing some text into a list item, or indenting it, is more cumbersome if it contains newlines, they have to be removed;

Emphasize, strongly, very strongly.

  • These are double and triple apostrophes, not double quotes.
''Emphasize'', '''strongly''',
'''''very strongly'''''.

You can also write italic and bold if the desired effect is a specific font style rather than emphasis, as in mathematical formulae:

F = ma
  • However, the difference between these two methods is not very important for graphical browsers, and many people choose to ignore it.
You can also write <i>italic</i>
and <b>bold</b> if the desired effect is a 
specific font style rather than emphasis, as 
in mathematical formulas:
:<b>F</b> = <i>m</i><b>a</b>
A typewriter font for technical terms.
A typewriter font for 
<tt>technical terms</tt>.
You can use small text for captions.
You can use <small>small text</small>

You can strike out deleted material

and underline new material.

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

  • The latter method of superscript can't be used in the most general context, but is preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.
