Help:Citation Style 2
Citation Style 2 (CS2) is a style applied to citations on Wikipedia. It is used by default in the general purpose citation template {{Citation}}, and available as an option in many other templates.

By default, the {{Citation}} template uses CS2 formatting. To apply CS2 formatting to other citation templates, add |mode=cs2 to the template's parameters. For example, {{cite web}} uses CS1 formatting, but {{cite web |mode=cs2}} uses CS2 formatting.
