Custom Styling

You can change the style by creating and modifying a custom style file ~/.config/gtk-3.0/gtk.css.

For instance, the screenshot (background was created with the Gimp render filter Flame):

was made with the following ~/.config/gtk-3.0/gtk.css:

.juci_window {
  background: url("/home/eidheim/Pictures/juci_background.png");
  background-size: 100% 100%;
}

.juci_directories * {
  background-color: rgba(255, 255, 255, 0.7);
}

.juci_directories *:selected {
  background-color: rgba(200, 200, 200, 0.6);
}

.juci_directories button * {
  background: transparent;
}

.juci_terminal {
  background: transparent;
}

.juci_terminal * {
  background: transparent;
}

.juci_terminal_scrolledwindow {
  background-color: rgba(255, 255, 255, 0.8);
}

.juci_notebook {
  background-color: rgba(255, 255, 255, 0.8);
}

.juci_notebook * {
  background: transparent;
}

textview.view text selection {
  background-color: #4a90d9;
}

.juci_entry {
  background-color: rgba(255, 255, 255, 0.8);
}

.juci_status_box {
  background-color: rgba(0, 0, 0, 0.8);
