SCSS and Angular
I am using https://scotch.io/tutorials/using-sass-with-the-angular-cli tuturial to remember how to do stylings with scss and Angular.
I did have to change the code a little.
"styles": [ "sass/styles.scss" ],
"styles": [ "src/sass/styles.scss" ],
Although, I refuse to use Bootstrap for any project. With CSS Grid and Flexbox, the need for Bootstrap has disappeared.
