Include a [hash]
in the destination filename to generate a unique hash code based on the source content:

Custom Configuration
This tool uses cssnano as the optimization module. By default it wil use all advanced optimizations provided by cssnano.
Use the --config
flag to pass a custom json configuration file. This allows you to enable / disable optimizations and to pass options to the individual optimization modules.
