In my angular 4 project I want to include one of Angular Material's prebuilt themes globally, so in my styles.css I put this import like explained in the angular.io:
@import "~@angular/material/prebuilt-themes/indigo-pink.css";
And in my angular.cli:
"styles": ["styles.css"].
My styles.css file have only that line and nothing else.
But for some reasons it seems that styles.css is not loaded. Do I need to do something else? Why this happening?
