Skinr is an extension for the Drupal web content management system. It allows to apply custom CSS classes to individual page elements being output in Drupal. These CSS classes are defined through atomic skin plugins. Each skin usually focuses on a certain appearance topic, implements multiple variants, and thus provides options for the user to choose from. The Skinr extension itself only provides an API to be consumed by other modules and themes, as well as a default user interface to configure skins.
