A Standard Skin can be selected and used as a default skin to use when ThemeBuilder is the Global theme in Confluence. When a Global or Personal space does not have a skin specifically selected, the Standard Skin selection is used. This allows you to choose a skin which all Personal or Global spaces should use. You may then, optionally, prevent space admins from selecting a skin, thus enforcing your corporate look and feel site-wide. The steps below direct you to the area of Confluence in which you can set the Standard Skin:
Go to the Confluence Administration icon, and select General Configuration.
Choose Standard Skin from the ThemeBuilder section of the left sidebar.
Select the desired options from the Standard Skin screen.
