I just found the amazing Stackblitz online VS Code editor. I created an Angular project and under dependencies installed the Bootstrap CSS framework but how
Check this StackBlitz example : https://stackblitz.com/edit/angular-wkc7ix?file=styles.css
It does have a angular-cli.json file and a style.css file
angular-cli.json :
{
"apps": [{
"styles": ["styles.css"]
}]
}
style.css :
@import "bootstrap/dist/css/bootstrap.min.css";
In angular.json:
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.css"
],
For me works just fine.
