Im following these instructions to change the color scheme of my project. However I don't see it working. This is the file in the module I am trying to shadow:
And this is my current file that I try to use to override the styles:
One thing that caught my attention is that if I am running my code with gatsby develop and I save one pages/styles.css gatsby deploys the file automatically but If I save the newest theme.css, gatsby doesn't do the same.
Can someone tell me if I am doing anything wrong? Should the changes be reflected automatically after "shadowing" them or I need to build the project again?
