Themes are used to change the appearance of your Confluence site. See Working with Themes for an overview of how themes apply to your whole site, and how you can add more themes. 

To apply a theme across the site:

  1. Go to 


    in the Confluence navigation
     > Themes
  2. Choose a theme
  3. Hit Confirm

All spaces that have the Global look and feel applied as their space theme will inherit this theme and any customizations you make to it.
