Сonnect 2 css files into one using gulp-rigger

[vtboren56]

Is it possible to connect 2 css files into one using gulp-rigger? And how to do it? I tried to do it: My main.css:

/*
 * Third party
 */
//= ../../bower_components/normalize.css/normalize.css
/*
 * Custom
 */
//= partials/style.css

Task for gulp:

gulp.task('css:build', function () {
    gulp.src(path.src.css)
        .pipe(rigger())
        .pipe(sourcemaps.init())
        .pipe(cssmin())
        .pipe(sourcemaps.write())
        .pipe(gulp.dest(path.build.css))
        .pipe(connect.reload());
});

But as a result I get:

//=../../bower_components/normalize.css/normalize.css //=partials/style.css
/*# sourceMappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJmaWxlIjoibWFpbi5jc3MiLCJuYW1lcyI6W10sIm1hcHBpbmdzIjoiIiwic291cmNlcyI6WyJtYWluLmNzcyJdLCJzb3VyY2VzQ29udGVudCI6WyIvKlxyXG4gKiBUaGlyZCBwYXJ0eVxyXG4gKi9cclxuLy89IC4uLy4uL2Jvd2VyX2NvbXBvbmVudHMvbm9ybWFsaXplLmNzcy9ub3JtYWxpemUuY3NzXHJcblxyXG5cclxuLypcclxuICogQ3VzdG9tXHJcbiAqL1xyXG4vLz0gcGFydGlhbHMvc3R5bGUuY3NzIl0sInNvdXJjZVJvb3QiOiIvc291cmNlLyJ9 */
