We recommend using the latest version of IE11, Edge, Chrome, Firefox or Safari.
To change the theme of your entire site (including the pages for items and collections), select "Themes" or "Appearance" from your dashboard. In this example, the theme is "Berlin." Additional themes can be found on the Omeka Website.
From this page, you can select any theme that you have already downloaded and customize it using the "Configure Theme" button.
You can also change just the theme for an exhibit on the edit page of that exhibit.
