Appendix C: CSS

Listing of CSS class names emitted from Foswiki core code and standard extensions.

Who should read this document?

Skin builders and others who want to change the appearance of the default installation or any of the skins can use this document to see what styles can be created for these html elements.

Naming conventions

  1. All Foswiki class names have the prefix foswiki - for example: foswikiAlert, foswikiToc. This makes it less likely that our CSS classes will get in conflict with other Style Sheets. Remember that CSS class names are case sensitive - Foswiki CSS uses lowercase foswiki.
  2. If you define your own CSS classes, it is preferable that you do not use the foswiki prefix to prevent undesired overriding effects.

A wide range of standard styles are used in the Foswiki core code and topics, and more are used in extensions. The following is an exhaustive list of all styles defined by Foswiki. For the most part, the names are the only documentation of the purpose of the style. For more information on how these styles are used, read the code (sorry!)
