title: How to make Angular-CLI compile SCSS to CSS in assets folder
body: <p>I have an Angular 4 project, created with angular-cli 1.0.x.
  At this time, angular-cli is upgraded to 1.1.1 in my project.</p>
  
  <p>I have an assets folder and when I put a css file in it, it can be used.
  But when I rename the css file to scss, it is not compiled by angular-cli.</p>
  
  <p>What do I need to do to get the scss file to be compiled to css?</p>
