userChrome.css file for a Zotero dark theme. Suggestions for improvements are welcome.

Created for Zotero 5.0.92. Windows 10 compatible. Cannot vouch for other OSes.

To use it follow the following steps:

1 - Go to your user Profile folder - C:\Users\User_name\AppData\Roaming\Zotero\Zotero\Profiles\user_profile.default\

2 - Create a chrome folder,

3 - Place the userChrome.css file in there,

4 - Start Zotero and enjoy

I encourage everyone to play around with this and try to improve on it and theme things that I didn't manage to. These include the following elements:

1 - couldn't theme the scrollbars (even tried creating a userContent.css like in Firefox but it didn't work),

2 - the tag box and tag text color,

3 - the menus colors,

4 - the New Item sub-menu in the File drop down menu (it assumes the white color of the menu categories),

5 - the sub-categories in the Preferences dialog. I am not satisfied with the preferences dialog but it's the best I could make it.
