grunt custom css into main.css - css

Question

I'm using grunt since recently. I have an app generated with yeoman and I've wrote some css code and I put it into /project/app/style/main.css.
When I start grunt command grunt serve into shell all works fine but my css isn't loaded. I don't understand what is the trick but apparently only sass and scss files are processed.
Any suggestion to solve?
this is my gruntfile.js

You have to actually somehow tell Grunt to include your css file, otherwise it won't know about its existence.
There's several ways you can do this, but since you're already using SASS which is being compiled and minified, an easy way would be to import your file as an scss file as well. This way you don't have to create separate rules and you can stay efficient.
Since SASS is a superset of CSS, your css file already is a valid .scss file too. If you rename it to _main.scss you can simply import it into any other scss file you already use in the project:
#import "main"
The underscore in the filename tells SASS to import it into the file that's being parsed instead of keeping it as a regular import (which would mean it needs to be copied to the dist and requires an http request to be loaded).
