I'm not sure what to put there. The manual entry [1] for GTK styling
links to a dead resource [2] concerning the GTK styling options. I
suppose it means to reference this page
<https://docs.gtk.org/gtk3/css-overview.html>

Still, that page doesn't say anything about toolbars.

I found this answer [3] which uses "gsettings" and as far as I know,
settings changed through gsettings do not affect Emacs, so I have to
create a stylesheet just as the manual says.

Any pointers?
