Themes are pre-defined style sets that you can apply to Confluence, to alter the appearance of your site. This is a way of personalising the 'look and feel' of Confluence. You can apply a theme to your entire Confluence site and to individual spaces. Choose a specific theme if you want to add new functionality or significantly alter the appearance of Confluence.
Confluence comes with a selection of themes. After a theme is installed on your Confluence site, any space administrator can apply a theme to a space.
A site administrator can install new themes as add-ons via the Confluence Administration Console.
By default when you create a new space, the space will have the Confluence default theme.
To look at the themes installed on your Confluence site:
Before installing an add-on (also called a plugin) into your Confluence site, please check the add-on's information page to see whether it is supported by Atlassian, by another vendor, or not at all. See our guidelines on add-on support.
Visit the Atlassian Marketplace to search for additional themes you can add to your site.
