The bulk of the infobox is generated by blocks of numbered parameters: headerX, labelX, dataX, dataXa, dataXb, and dataXc. The following examples demonstrate the order in which these parameters are used.

end
return ret
end

-- for the specified prefix. For example, if the prefix was 'data', and

Loads the templatestyles for the infobox.

See [[Mediawiki_talk:Common.css/to_do#Infobox]] and/or come help :).
When we do this we should clean up the inline CSS below too.
Will have to do some bizarre conversion category like with sidebar.
