Let’s start with an explanation of some terms you will see in this ThemeBuilder documentation.
What is a Confluence Theme?
ThemeBuilder is a theme in the sense that it can be selected as an alternative to the default Confluence theme in Confluence Administration. To select ThemeBuilder as your Theme:
Under Jira Settings, click System.
The Look and Feel menu is displayed in the left sidebar.
What is a ThemeBuilder Skin?
A skin is the collection of editable panels that make up one whole page framework that can be applied to Confluence through ThemeBuilder. You can have multiple skins in the Skin Editor and each can be applied automatically to individual spaces, pages, actions and similar options to finely tune user experience.
In previous versions of ThemeBuilder a skin was called the layout.
