Wikipedia:Catalogue of CSS classes

Many links to CSS files on this page are dead, therefore its contents should not be trusted until it is thoroughly checked and rewritten.

The website HTML, generated Wikipedia content and the JavaScripts of Wikipedia define hundreds of classes and IDs. The use of most of them is not clearly explained or described anywhere. Most of these classes and IDs are used for styling using CSS and identify parts of the page that this styling should apply to. They can also be used to make manipulations to the webpages using JavaScript and some have additional semantic meaning and are used by external parties.

This page is an attempt to catalogue and describe the most used and most important classes and IDs used on this wiki.
