A XWiki skin is used to customize the interface of a XWiki Enterprise instance. Skins are composed of templates, CSS files, JavaScript files, images and fonts. Several skins have been bundled with XWiki over the years, including Dodo, Finch, Albatross, Toucan, Colibri and Flamingo. There is ongoing discussion around improving skin support and flexibility in XWiki, including whether to introduce new skins, make the current skin (Flamingo) more configurable, integrate themes, and define standards and an extensibility model to balance simplicity and customizability.
