grunt-contrib-cssmin - how to remove comments from minified css

Question

Im using cssmin to minify css files.

my config like this:

module.exports = function(grunt) {

    grunt.config.set(\'cssmin\', {
        site: {
                 


        

Answer 1

Set keepSpecialComments to zero, for removing all comments.

grunt.config.set('cssmin', {
    options: {
        keepSpecialComments: 0
    },
    site: {
        src: ['.tmp/public/concat/site.css'],
        dest: '.tmp/public/min/site.min.css'
    }
});

For future reference: grunt-contrib-cssmin uses clean-css options.
