WikiStyles allow an author to modify the color and other attributes of text that follow. A style specification such as
%red% will cause the following text to be displayed as red until the end of the line or the next pair
%% of percent signs. For example:
%red% This text is red and %blue% this text is blue %% but this text is normal.
The set of predefined wiki styles? is customizable by the WikiAdministrator. Most PmWiki systems define %newwin% to cause links to open in a new window (example), and standard text colors such as %black%, %white%, %red%, %green%, %blue%, etc.
target specifications inside of a pair of percent signs will change the style of the following text to use those colors up to the end of a line or until the next pair of percent-signs. For example:
%color=red% This text is red and %color=blue% this text is blue %% but this text is normal.
If one wants the formatting to continue past the end of the line, there are a couple options one can use (found here).
For example, using %block color=red% will continue the formatting until it gets to to the end of the current block/paragraph. For example:
This is some text %block color=red% that is being colored red by the wikistyle in the line.
This is some text that is being colored red by the wikistyle in the line.
The other options (according to the e-mail) are:
One can also change the background color using the
%color=black bgcolor=green% This text is black on green %color=green bgcolor=black% and this is green on black.%%
This text is black on green and this is green on black.
One can specify that links should open in a new window via the
%target=_blank% Any links on this line like http://www.pmichaud.com will open in a new window.
Finally, WikiStyles can control the width and height of ImagesInWikiPages, thus the markup
will display some.gif scaled to a height of 50 pixels.
Wiki authors can also make their own WikiStyle definitions within a document using the
define attribute. For example, the statement
will cause the markup
%hotpink% to be a shortcut for
%color=#ff69b4% (like this). One can specify multiple items in a definition, as in
%define=reverse color=white bgcolor=black%
%reverse% to cause reverse video, and
%reverse hotpink% to be the combination of both shortcuts.
It's often a good idea to put common style definitions into GroupHeaders so that they can be shared among multiple pages in a group. Or, the WikiAdministrator can predefine styles as a LocalCustomization -- see WikiStylesAdmin.
See predefined wiki styles? for a description of the WikiStyles that are defined in a standard installation of PmWiki. That page also describes how an administrator can predefine additional WikiStyles.
