I am doing assets pre-compile, and running the application in production mode. After compilation when I load the my index page I got followings warnings in the chrome consol
My issue was that I was declaring two fonts, and scss seems to expect that you declare the name of the font.
after your @font-face{} you must declare $my-font: "OpenSans3.0 or whatever";
@font-face{}
$my-font: "OpenSans3.0 or whatever";
and this for each font-face.
