title: where is angular-cli.json file in ionic 3?
body: <p>I wanted to include a third party module( <a href="https://www.npmjs.com/package/ngx-intl-tel-input" rel="nofollow noreferrer">https://www.npmjs.com/package/ngx-intl-tel-input</a> ) in my app. They have asked us to insert their style sheet in angular-cli.json. Where I can I find this file in ionic 3 or any other way to add this stylesheet? Thank you.</p>
