Spaces removed from :not statement #996
Description
Hello,
I have been using gulp wrapper of this package and have noticed the whitespace is removed from :not statements.
Basically if i have css:
button {
&:not(.gmap &){
@include button();
}
}
The compiled css becomes (notice the space removed from .gmap and button:
button:not(.gmapbutton){/* the mixin css */}
When using the following gulp process:
return gulp.src(cssPath + '/**/*.css')
.pipe(groupMediaQueries())
.pipe(cleanCss({
compatibility: ie8,
level: 2
}))
.pipe(gulp.dest(cssPath));
