Template:Eras/doc

Syntax:  or
 * Type is "ages" or "eras" without quotes for the respective display modes. Ages go at the top of the page and eras go in the eras parameter of the nation infobox.
 * Age1...Age6 or Era1...Era13 are the names of ages or eras (see list below).
 * Width (should only be necessary for Ages) can have the values of "nation" or "officeholder" to make it match the width of Nation infobox and Infobox Officeholder, respectively, or a custom width (in pixels; don't add "px" suffix). Default is auto, which will make it just the width of the ages used. A custom width can be used with eras and will default to filling the width of the infobox.
 * NOTE: for Eras, the header is automatically positioned just above where the eras box will be. However, if a flag is used, and its width:height ratio is not 9:5 (i.e. its display height in the infobox isn't 50px), the  parameter must be used with the nation infobox and set to the display height of the flag (without the "px" suffix).
