Template:Colorbox/doc

This template supersedes legend3.

Usage

 * Colors are most commonly specified as either a color keyword or as the hexadecimal triplet representing an RGB combination. See web colors for details.
 * Text is optional; it is displayed using the default style foreground color as prescribed by CSS. For most users this is black.
 * The wikilink parameter is also optional and specifies the article to which the text should point.

NOTE: Using a blue, purple, or red colorbox obscures unvisited, visited, and missing wikilinks, respectively, as these are the default link colors for most users.

Legends and keys
The  template is widely used to annotate complex tables in which editors have used color to group like entries. The editor uses the  style to color individual cells in the table and then adds a legend consisting of colorboxes at the beginning or end of the table explaining the meanings behind the color scheme. The editor may also add symbols like a caret (^), dagger/obelisk (†), double dagger/diesis (‡), or asterisk (*) to call attention to the different meanings.

NOTE:
 * 1) Using a black colorbox with text markers obscures the text as the default style foreground color for most users is black.
 * 2) The HTML code  must be used to create the asterisk as Wikipedia will treat the typed asterisk as an indented bullet point.
