userChrome.css file for a Zotero dark theme. Suggestions for improvements are welcome.
New version available for Zotero 6. Created for Zotero 5.0.92. Windows 10 compatible.
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 - Scrollbars (that is usually done via userContent.css in Firefox but it doesn't work in Zotero),
2 - New PDF reader,
3 - Note editor (in Zotero 6),
3 - Menu colors,
4 - Sub-categories in the Preferences dialog. Not satisfied with the preferences dialog but it's the best I could make it.
If you wish to explore for additional elements to alter: 1 - Go to the folder of my Zotero install (C:\Programs(x86)\Zotero);
2 - Copy the zotero.jar folder to another folder;
3 - Use 7zip to unzip zotero.jar to a zotero folder;
4 - Go to D:\X\zotero\chrome\skin\default\zotero;
5 - Look at ALL .css files in this folder;
6 - Start testing different pieces of code to change the defaults in the userchrome.css file.
To implement a dark theme in the Note Editor in Zotero 5 (credit to 10cks) follow the subsequent steps:
1 - Start Zotero;
2 - Go to Preferences -> Advanced -> Config Editor;
3 - Select "I accept the risks!";
4 - Search extensions.zotero.note.css and double-click it;
5 - Insert the string in the Note_editor_css.txt file;
6 - click "OK" or close the dialog box;
7 - Restart Zotero.
