قالب:LinkCatIfExists2/doc

This a simple helper template, to be used in other templates. It displays a link to a category if that category exists; otherwise it just displays plaintext in grey, to reduce the visual prominence of the unlinked text.

An optional display text may be added as a second parameter.

 Purpose

This template is a variant of {{LinkCatIfExists}}, which does no greying.

The greying was designed to improve the clarity of category header templates such as {{EstcatContinentCentury}}.
