+ +
+ +This plugin can be used to color a piece of text on Ikiwiki page.
+ +It's possible setting foreground and/or background color of the text.
+ +
+ +The plugin syntax is very simple. You only need to type name (e.g. `white`)
+ +or HTML code of colors (e.g. `#ffffff`) and a text you want to color.
+ +The colors should by separated using a comma character.
+ +
+ +Below are a few examples:
+ +
+ + \[[!color white,#ff0000 "White text on red background"]]
+ +
+ +Foreground color is defined as a word, background color is defined as HTML
+ +color code.
+ +
+ + \[[!color white "White text on default color background"]]
+ +
+ +Foreground color is default color if only one color was typed and a comma
+ +character is missing.
+ +
+ + \[[!color white, "White text on default color background"]]
+ +
+ +Background color is missing, so the text is displayed on default background.
+ +
+ + \[[!color ,#ff0000 "Default color text on red background"]]
+ +
+ +Foreground is missing, so the text has default color.
+ +
+ +This plugin is not enabled by default. You can do that in [[ikiwiki.setup]]
+ +file (hint: `add_plugins` variable).
