Changing the look of new Gnome 3 title bars in with a GTK3 theme

Question

I have a GTK3/Metacity theme which uses dark title bars.

Recent versions of Gnome 3 combine title- and toolbars, e.g. in Nautilus. I want to change their color to be consistent with all other GTK windows.

What is the attribute I need to look for?

Answer 1

The source code for the GTK+ themes is located in the https://git.gnome.org/browse/gnome-themes-standard/ git repository. The styling for the different widgets for Adwaita is located in the themes/Adwaita/gtk-3.0/gtk-widgets.css file -- see the section starting:

/***************
 * Header bars *
 ***************/

Specifically:

• .header-bar { ... }
• .header-bar:backdrop { ... }
• .header-bar .button.text-button { ... }
• .header-bar .button.image-button { ... }

Although not 100% sure, I thought Nautilus is a GTK2 application. If that is the case, you need to create a GTK2 theme next to your GTK3 theme.

You can put these folders next to each other.

Take a look in your /usr/share/themes folder for examples.

Does this help you?

Answer 3

You could install gtk-tweak-tool and configure your system to global-dark-theme.
