/* Answer to: "how to use scss in html" */

/*
  Unfortunately, you can't directly insert an SCSS (Sassy CSS) file
  into your HTML. That's because SASS is a superset (or so-called
  preprocessor or extension) of CSS3's syntax, which is NOT
  supported by web browsers.

  To take full advantage of all the incredible features offered by
  SCSS in your HTML page, you’ll first have to compile it down
  to CSS.

CSS code that your browser understands.
