Themes are used to define a particular look and feel for Confluence. Use themes if you want to add a new functionality or to significantly alter the appearance of Confluence. Themes can be applied to the whole site or to an individual space.

To create a new theme,

1. Create the decorator files that define how the different content types are laid out
2. Create the colour scheme for the space
   Optionally, use a stylesheet which will override the styles defined in the decorator files
