minfication of CSS

[bdelaney]

I notice that in the Gulp project you document how to send the CSS stream for minification. Is this possible in the Grunt version, or an option for a template that I have not found. No problem if not, can always minify as post-processing step in build.

In gulp.spritesmith, the minification is done via a separate module. Both grunt and gulp build systems focus on tasks doing one thing well and chaining to perform higher level actions (e.g. building/minifying).

For the grunt integration, it's recommended to save to a separate temporary file and then generate the minified result from that. Then, we can register a task that does both:

grunt.registerTask('sprite-and-minify', ['sprite', 'minify']);

This is one of the major complaints about grunt; there is no interim state to share between tasks.
