How to style SASS output file in gulp?
By default, there is a nested style, which is not quite familiar to me, how can I change it?

Answer 1

outputStyle
:nested
:compact
:expanded
:compressed

gulp.task('sass', function () {
 return gulp.src('./sass/**/*.scss')
   .pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))
   .pipe(gulp.dest('./css'));
});
