Help:Extension:ProofreadPage/Index-specific CSS/en

Every Index page can have a CSS stylesheet added (as long as Extension:TemplateStyles is installed). This CSS stylesheet is applied to every page in the Page namespace, and also to Page pages that are transcluded with the  tag.

Creating the stylesheet
To create an Index stylesheet, all you need to do is add a  subpage. For example, create. This will be automatically applied to all Page-namespace page in that Index.

Targeting elements
The ability to target specific element on a page depends on the wiki, as these are usually added in templates. Generally, elements are targeted by classes:

It is suggested that classes added by templates use a common prefix (e.g. English Wikisource uses ) to make it obvious that a certain class originates in a template.

Using an underscore as a prefix for work-specific classes also makes is less likely that this Index-specific CSS will collide with built-in MediaWiki CSS.

CSS
The CSS used is a subset of CSS called. Some features are not used, for example data URLs and some browser-prefixed or non-standard CSS properties.
