- ref: the citation's HTML anchor identifier, when different from its default. When set,
|{{SAFESUBST:#if:ref|ref=}}ID
generates an anchor with the given ID
(the id=
attribute in the citation's {{#switch:o
|c|close =
|e|empty|s|single|v|void
|o|open
|p|pair = <{{#if:|cite|cite}}{{#if:id="ID"| id="ID"}}
}}{{#switch:o
|c|close =
|e|empty|s|single|v|void = />
|o|open = >
|p|pair = {{#ifeq:cite|!--||>}}...
}}{{#switch:o
|e|empty|s|single|v|void
|o|open =
|c|close
|p|pair = {{#ifeq:cite|!--|-->|</cite>}}
}}
HTML tag). Setting |{{SAFESUBST:#if:ref|ref=}}ID
identifies the template as a target and allows wikilinking to full references, especially useful with short-form citations like shortened notes and parenthetical referencing. The default anchor ID is suitable for use with {{sfn}} and {{harv}} templates. Since April 2020, the parameter / keyword pair |{{SAFESUBST:#if:ref|ref=}}harv
has no special meaning; this deprecated setting should not be used and may be removed from existing cs1|2 templates. To inhibit anchor ID creation, set |{{SAFESUBST:#if:ref|ref=}}none
. Aliases: none. {{#ifeq:{{#titleparts: Template:Citation Style documentation/ref | 1 }}| Template:Citation | | See Template:Citation/doc § Anchors for Harvard referencing templates. }}
