Using this as my guide https://github.com/angular/angular-cli#global-library-installation
, I added these two lines of code in my angular-cli.json file,like so and installed bootstrap by running npm install bootstrap@3. But still the bootstrap css is not taking over in my app.
I also added this line in my index.html but did not help.
<link href="node_modules/bootstrap/dist/css/bootstrap.css" rel="stylesheet" />
