Sass (Sass) Question

Why my comments between /* and */ in my SCSS file are taken into account?

Gulp watch
yields errors related to code between
in my
file, although I've read that this is a regular way of commenting in
. Any idea why I have this problem?


Error: Undefined variable: "$sm-breakpoint".

SCSS has two kinds of comments:

[SCSS] supports standard multiline CSS comments with /* */, which are preserved where possible in the output. These comments can have whatever formatting you like; Sass will do its best to format them nicely.

SCSS also uses // for comments that are thrown away

Especially, SCSS interprets interpolated expressions (#{..}) within /* */. If you place the $sm-xx definitions into // style comments, the file will compile. (Note that you cannot nest comments. The // lines must be outside of the /* */ block.)
