Appendix C: TWiki CSS

Listing of CSS class names emitted from TWiki core code and standard plugins.

Who should read this document?

Most HTML elements generated by TWiki core code now have Cascading Style Sheet (CSS) tags. Skin builders and others who want to change the appearance of the default TWiki 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 TWiki class names have the prefix twiki. So: twikiAlert, twikiToc, etc. Remember that CSS class names are case sensitive - TWiki CSS uses lowercase tw.
  2. If you define your own CSS classes, it is preferable that you do not use the twiki prefix to prevent undesired overriding effects.

A wide range of standard styles are used in the TWiki core code and topics, and more are used in plugins. The following is an exhaustive list of all styles defined by the PatternSkin. 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!)
