Wiki style basics

Wiki styles allow authors to modify the color and other styling attributes of a page’s contents. A wikistyle is written using percent-signs, as in %red% or %bgcolor=lightblue%.

Text color and font

The most basic use of wiki styles is to change text attributes such as color, background color, and font. PmWiki defines several wikistyles for changing the text color to %black%, %white%, %red%, %yellow%, %blue%, %gray%, %silver%, %maroon%, %green%, %navy%, and %purple%.

The basket contains %red% apples, %blue%
blueberries, %purple% eggplant, %green%
limes, %% and more.

For colors other than the predefined colors, use the %color=...% wikistyle. (Note: RGB colors (#rrggbb) should always be specified with lowercase letters to avoid WikiWord conflicts.)

I'd like to have some %color=#ff7f00%
tangerines%%,  too!

To change the background color, use %bgcolor=...% as a wikistyle:

This sentence contains %bgcolor=green
yellow% yellow text on a green
background.

See Wiki Style Colors for more color help.

Text justification

Styles are used to control the text justification

%center% This text is centered. 

%right% Right justified.

and to create floating text:

%rfloat% This text floats to the right

%rframe% floats to the right with a
frame

Lorem ipsum dolor sit amet,
consectetuer sadipscing elitr

Scopes

Wikistyles can also specify a scope; with no scope, the style is applied to any text that follows up to the next wikistyle specification or the end of the paragraph, whichever comes first. The apply= attribute and its shortcuts allow to change the scope as follows:

thus %p color=blue% is the same as %apply=p color=blue%, and %list ROMAN% is the same as %apply=list list-style=upper-roman%.

Some predefined style shortcuts also make use of apply, thus %right% is a shortcut for %text-align=right apply=block%.

Example: Apply a style to a paragraph:

%p bgcolor=#ffeeee% The wikistyle specification at the beginning of this
line applies to the entire paragraph, even if there are %blue% other
wikistyle specifications %% in the middle of the paragraph.

Caveat: An applied wikistyle will only take effect if it’s on the line that starts the thing it’s supposed to modify. In other words, a wikistyle in the third markup line of a paragraph can’t change the attributes of the paragraph:

after the first line of the paragraph,
we try to %apply=p color=blue% change
color.
This does't work because the style
comes

However, this %p color=red% paragraph
''will'' be in red because its block
style does
occur in the first line of its text.

* Here's a list item
* %list red% Oops, too late to affect
the list!

Wiki style syntax for tables and directives

Wiki styles can also be applied to tables and table directives. Unfortunately the syntax is inconnsistent, so you will have to experiment to get the result you require.

||class="green"
style="font-style:italic; border:1px
solid blue; background-color:#ffffcc"
||Everything after the above line is
styled with green italic text, ||
|| ||
||This includes ||
||    preformatted text ||
||* lists ||
||-> indented items ||

(:table class="green"
style="font-style:italic; border:1px
solid blue; background-color:#ffffcc":)
(:cellnr:)
Everything after the above line is
styled with green italic text,

This includes
    preformatted text
* lists
-> indented items
(:tableend:)

   preformatted text

The >>style<< block can be used to apply a wikistyle to a large block of items. The style is applied until the next >><< is encountered.

>>blue font-style:italic
bgcolor=#ffffcc<<
Everything after the above line is
styled with blue italic text,

This includes
    preformatted text
* lists
-> indented items
>><<

   preformatted text

The (:div style:) works in almost the same way as >>style<<, but the style information is encapsulated in a style=“ ” attribute and nested div blocks are possible.

(:div class="green"
style="font-style:italic; border:1px
solid blue; background-color:#ffffcc":)
Everything after the above line is
styled with green italic text,

This includes
    preformatted text
* lists
-> indented items
(:divend:)

   preformatted text

(:div1 style="font-style:italic;
background-color:#ffffcc":)
outer style
(:div2 style="color:red;
background-color:lightblue":)
nested style
(:div2end:)
again outer style
(:div1end:)

Wikistyle attributes

The style attributes recognized within a wikistyle specification are:

   ------------ CSS -------------          —HTML—
   color               bgcolor             class 
   background-color    margin              id
   text-align          padding             hspace
   text-decoration     border              vspace
   font-size           float               target
   font-family         list-style          rel
   font-weight         widthfn              accesskey
   font-style          heightfn             value
   display

   Special: define, apply

The attributes in the first two columns correspond to the cascading style sheet [1] (CSS) properties of the same name. The attributes in the last column apply only to specific items:

• class= and id= assign a CSS class or identifier to an HTML element
• target=name opens links that follow in a browser window called “name”
• rel=name in a link identifies the relationship of a target page
• accesskey=x uses ‘x’ as a shortcut key for the link that follows
• value=9 sets the number of the current ordered list item

Enabling Styles

Styles not listed above can be enabled by a PmWiki Administrator by modifying the local/config.php file. For instance to enable the “line-height” style attribute add the line

to the local/config.php file.

Custom style shortcuts

The define= attribute can be used to assign a shorthand name to any wikistyle specification.\\ This shorthand name can then be reused in later wikistyle specifications.

%define=box block bgcolor=#ddddff
border="2px dotted blue"%

%box% [@some sort of text@]

%box font-weight=bold color=green%
[@some sort of text@]

Predefined style shortcuts

PmWiki defines a number of style shortcuts.

• Text colors: black, white, red, yellow, blue, gray, silver, maroon, green, navy, purple (shortcut for %color=...%)
• Justification: %center% and %right%
• Images and boxes
  • Floating left or right: %rfloat% and %lfloat%
  • Framed items: %frame%, %rframe%, and %lframe%
  • Thumbnail sizing: %thumb%
• Open link in new window: %newwin% (shortcut for %target=_blank%)
• Comments: %comment% (shortcut for %display=none%)
• Ordered lists: %decimal%, %roman%, %ROMAN%, %alpha%, %ALPHA% (see also Cookbook:OutlineLists)

Examples

Wiki Style Examples contains a number of examples of ways to use wikistyles in pages.

Known Issues

• Percents in style definitions (like: %block width=50% %) require the use of “pct” instead of “%”.
• If you specify multiple values for an attribute, like border=“2px solid blue” make sure you place the values in quotes.
• Be sure to use lowercase letters for red-green-blue hex colors, %color=#aa3333% will work, %color=#AA3333% may not.
