Editing Help:CS1 errors (section)

=== Properties category highlighting ===

<section begin="prop_cat_highlight_help_text" />
[[Module:Citation/CS1]] adds properties categories to some CS1|2 citations.  Unlike errors or maintenance needs, there is no message when a properties category is added.  Properties categories may be temporary or may be perpetual.  Editors can use CSS to add special styling to CS1|2 template renderings that will highlight a citation that added a properties category.  For example, this template uses a long volume name:
:<code><nowiki>{{cite book |title=Title |date=May–Jun 2021 |volume = 1: Long volume}}</nowiki></code>
::{{cite book |title=Title |date=May–Jun 2021 |volume = 1: Long volume |no-tracking=y}}
If you add this to your CSS that citation will render with a {{background|#FFC|pale yellow}} background:
:<syntaxhighlight lang="css">.cs1-prop-long-vol {background: #FFC;}</syntaxhighlight>
Add one or more of these (with appropriate styling) to your CSS to highlight template renderings when those templates add the associated properties category:
::{{code|lang=css|.cs1-prop-foreign-lang-source {}|}} – subcategories of {{cl|CS1 foreign language sources}}
::{{code|lang=css|.cs1-prop-foreign-lang-source-2 {}|}} – {{cl|CS1 foreign language sources (ISO 639-2)}}
::{{code|lang=css|.cs1-prop-interwiki-linked-name {}|}} – author, contributor, editor, interviewer, translator name(s) linked to another language Wikipedia
::{{code|lang=css|.cs1-prop-interproj-linked-name {}|}} – author, contributor, editor, interviewer, translator name(s) linked to another MediaWiki project
::{{code|lang=css|.cs1-prop-location-test {}|}} – {{cl|CS1 location test‎}}
::{{code|lang=css|.cs1-prop-long-vol {}|}} – {{cl|CS1: long volume value}}
::{{code|lang=css|.cs1-prop-script {}|}} – subcategories of {{cl|CS1 uses foreign language script‎}}
::{{code|lang=css|.cs1-prop-tracked-param {}|}} – subcategories of {{cl|CS1 tracked parameters}}
::{{code|lang=css|.cs1-prop-year-range-abbreviated {}|}} – {{cl|CS1: abbreviated year range‎}}
