Note: To install it globally i.e. for situation when you run apps as root or specially SNAP packages move your theme to /usr/share/themes



Here is the link to the trello board for the project > board.


This stylesheet doesn’t need to be compiled. It is recommended to make a symbolic link from the source directory to “/usr/share/themes” for testing:

ln -s /path/to/your/branch /usr/share/themes/

Apps will need to be restarted or the system stylesheet will need to be changed for your changes to take effect.

You can also test changes live with Gtk Inspector. Make sure you have Gtk development libraries installed:

sudo apt install libgtk-3-dev

Open an app you wish to test your changes on. Open Gtk Inspector with the keyboard shortcut Shift + Ctrl + D, then navigate to the tab “Custom CSS”. Your changes here will take immediate effect on the focused app.
