angular cli build does not include css component

Question

Reading the angular-cli documentation and some discussion on stack overflow I had understand that when a project is done with generated components, the inline styles will be all included in the build by default, but when I build my project it seems that none of the inline styles were included.
For example this component:

Component

import { MenubarService } from '../../services/menubar-service/menubar.service'
 
@Component({
    selector: 'app-login',
    templateUrl: './login.component.html',
    styleUrls: ['./login.component.css'],
    providers:[LoginService]
})
export class LoginComponent implements OnInit {
    constructor(.......

the login.component.css file is not present in the final project. I have noticed it for two reason:
First clearly the style of my app is different from the one that I have when I use 'ng serve' command and second because with the browser inspector element I don't find trace of my css.
That's my angular-cli's configuration file

{
  "project": {
  "version": "1.0.0-beta.18",
  "name": "genioimprese"
},
"apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": [
        "images",
        "assets",
        "favicon.ico"
      ],
      "index": "index.html",
      "main": "main.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.json",
      "prefix": "app",
      "mobile": false,
      "styles": [
        "styles.css",
        "paper.css"
      ],
      "scripts": [],
      "environments": {
        "source": "environments/environment.ts",
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "addons": [],
  "packages": [],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    } 
  },
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "prefixInterfaces": false,
    "inline": {
      "style": false,
      "template": false
    },
    "spec": {
      "class": false,
      "component": true,
      "directive": true,
      "module": false,
      "pipe": true,
      "service": true
    }
  }
}

except for some styles and assets it's clearly the default file of a new angular-cli projects. I think there's something wrong in my configuration file but the only documentation that I found is here, and I didn't find anything that helps me.

CSS

a{
    color: #0c699e;
}
a:hover,a:active,a:focus{
    color: #218fce;
}

.login{
    text-align: center;
    background-color: white;
    height: 100%;
    padding-top: 7%;
}
.login > .logo{
    height: 30%;
    width: 50%;
}
.input[type='text']{
    background-color: grey;
    color: #218fce;
    border: none; 
    border-radius: 0;
}  
h4{
    color: #218fce;
}
.form-group{
    margin-bottom: 10px;
}
form{
    margin-bottom: 0px;
}
.checkbox-inline{
    margin: 0;
}

I know this is an old question but Angular's CLI now includes some CSS optimization options which just now caused my app's global stylesheet to output as media=print.

Despite having NO print MQs, this media attr obviously causes no styles to be applied.

<link rel="stylesheet" ... href="styles.css" media="print">

"architect": ...
"build": ...
"configurations": {
  "dev": {
    ...
    "optimization": {
      "scripts": true,
      "styles": {
        "minify": true,
        "inlineCritical": false <--- fix
      },
      "fonts": true
    }
