    },
    less: {
      production: {
        files {
          "public/css/style.css": ["less/*.less"]
        },
      },
    },
    autoprefixer: {
      single_file: {
        src: "public/css/style.css",
        dest: "public/css/style.css"
      }
    },
  });
  grunt.loadNpmTasks("grunt-contrib-jshint");
  grunt.loadNpmTasks("grunt-contrib-less");
  grunt.loadNpmTasks("grunt-autoprefixer");

  grunt.registerTask("css", ["less", "autoprefixer"]);
  grunt.registerTask("default", ["jshint"]);
