title: Explanation of and structure of new angular.json file (angular-cli 6.x)
body: <p>The new angular.json file in angular 6.x, has, as part of its structure the following</p>
  
  <pre class="lang-js prettyprint-override"><code>"styles": [{
    "input": "src/styles.scss"
  }],
  "scripts": []
  },
  </code></pre>
  
  <p>My current angular/cli v1.72 has the equivalent in the .angular-cli.json</p>
  
  <pre class="lang-js prettyprint-override"><code>"styles": [
    "../scss/bootstrap/bootstrap.scss",
    "../src/assets/styles/icon8.css",
    "styles.scss",
    "styles-props.css"
  ],
  "scripts": [
    "../node_modules/web-animations-js/web-animations.min.js",
    "../node_modules/jquery/dist/jquery.js",
  ],
  </code></pre>
  
  <p>How can I convert the v1.7.2 to v 6.x format?
  What does the 'input' in the new format represents?</p>
  
  <p>Cheers</p>
