Avoiding CSS warnings in console
GTK CSS has a specific format in order to be parsed without warnings. The format is as follows:
<widget name/selector> {<property>: <value>;}
For example:
GtkWidget {background-color: rgba(255, 0, 0, 255);}
Forming CSS strings with this format will not cause any warnings. Additional semi-colons will cause problems. Note that only one semi-colon is needed.
Please note that the selectors have changed for GTK3.20+, so using things like GtkWidget as a selector will not work. Thankfully, GTK3 CSS is now part of the API, so you can look up the proper selectors here.
