I've recently been playing with Materailize CSS, and It's beautiful. Here's how you install it in Angular 6.

1. Once you've created your project, open up your terminal and run:
npm i materialize-css@next jquery --save

This installs Materailize CSS and jQuery.

2. Open up your angular.json file and add the style and scripts.

"styles": [
  "scripts": [

3. Restart your server and you should be ready to go!
