I will read it more carefully when I have some spare time. This morning I was looking for the exact meaning of single ampersand as in tooltip { &.background { In that page only double ampersand is mentioned unfortunately. And I have to admit that I have not bookmarked that page already -- "Copyright © 2005‒2014 The GNOME Project" made me wonder if that info is valid at all for GTK >= 3.20.
