I found the documentation pages
https://goodies.xfce.org/projects/applications/xfce4-notifyd
https://docs.xfce.org/apps/notifyd/theming

with examples such as:
https://git.xfce.org/apps/xfce4-notifyd/tree/themes/gtk-3.20/ZOMG-PONIES!/gtk.css

However there doesn't seem to be difference between a warning message
and an information message. Should I open a feature request?
