Template:Circa

Template documentation[view] [edit] [history] [purge]

Usage

This template generates an abbreviation for circa: c. By default the abbreviation is marked with <abbr>.

Examples

Syntax	What it looks like	Notes
{{circa}} 1325	c. 1325	Default style; line break allowed between "c. " and "1325"; normal-width space
{{circa|1325}}	1325c. 1325	Default style: no line break allowed; thin space
{{circa|1325|i=yes}}	1325c. 1325	With italic "c.", though italics are discouraged at MOS:CIRCA
{{circa|1325|lk=abbr}}	1325c. 1325	With abbreviation marking only (default)
{{circa|1325|lk=yes}}	1325c. 1325	With link only
{{circa|1325|lk=no}}	1325c. 1325	With neither link nor abbreviation marking
{{circa|1000|1050}}	1000c. 1000	For ranges

Parameters

Using the date itself as parameter (for example, "{{circa|1956}}", giving "1956c. 1956 "), web browsers do not insert a line break anywhere in the string. By contrast, "{{circa}} 1956" allows a line break between the "c. " and the number. Also, with the date as a parameter a thinner space is used with many browsers:

• "1956c. 1956 " is generated by "{{circa|1956}}".
• "c. 1956" is generated by "{{circa}} 1956".

If the parameter |i= is set to a non-empty value, the "c." is put in italics: for example, "{{circa|i=''}}" generates "c. " instead of "c. ".

If the parameter |lk= (for "link") is set as "|lk=no" or "|lk=off", the abbreviation is rendered as "c. ", without a wikilink or abbreviation element. If it is set to "|lk=abbr", it is rendered with the abbreviation element but without the wikilink. If it is set to "|lk=yes" or "|lk=on", it is rendered as "c. ", with a wikilink to the circa article and not an abbreviation element. Otherwise, the abbreviation is marked with the "<abbr>" element, as in "c. ", and linked to the circa article. The lk parameter can be used to avoid overuse of "<abbr>" or overlinking when this template is used repeatedly in the body of an article. For example:

• [[Dionysius Exiguus]] was born {{circa|470}}, lived in Rome from {{circa|lk=no|500}}, and died {{circa|lk=no|544}}.

  → Dionysius Exiguus was born 470c. 470 , lived in Rome from 500c. 500 , and died 544c. 544 .

If the parameter "cap=yes" is specified, the result starts with a capital letter.

If the parameter "sortable=yes" is specified, the template generates invisible text that will cause the output to work in sortable tables, at the cost of causing problems for visually-impaired readers. Compare "Col 1" and "Col 2" in the following table:

Title	Col 1	Col 2
Foo	1066	1066
Bar	c. 1510	1510c. 1510
Baz	1956	1956
Jaz	c. 410	410c. 410

"Col 1" uses {{Circa}} 1510, and does not sort correctly. "Col 2" uses {{Circa|1510|sortable=yes}}, and does sort correctly. This works because {{Circa|1510|sortable=yes}} inserts an invisible span element at the start of the cell: <span style="display:none;">1510</span>. Although it is not rendered, it is still seen by the sorting code and makes sorting work.

The downside of this approach is that the invisible text is still rendered by screen readers that are used by visually impaired readers, and by text browsers such as Lynx, so the table will become garbled for readers who are using assistive technology or text browsers.
