Please is is possible to change the background color of GTK titlebar via CSS?
I have tinkered with various combinations of .headerbar and .titlebar.default-decoration (I looked through the gtk-contained.css file) CSS classes but no luck.
I want to achieve a uniform theme in my application. For example, if the general theme of the application is blue, I want the titlebar to be some shade of blue.
Kindly point me in the right direction if it is possible to achieve this.
I have also considered creating a custom titlebar but I won’t have the native windows icons (minimize, maximize and close).
P.S. I am targeting Windows platform and developing using Msys2.
