The Custom CSS box allows you to input any CSS for that particular theme. Any background image you might add should come from an HTTPS domain as to not break the secure connection on 4chan. See imgur or imgbb.

Base64-encoded data URIs are also compatible.

Exporting Themes

In the Themes tab click the Edit button for your particular theme. In the window that opens, click Export. A .JSON file will be generated that you save can by clicking the now Save me! button.
