CSS can be optimized by compressing all different CSS files into one (or minimum number of files). Also removing all spaces and comments in the CSS file helps. This can be done using 3rd party CSS optimizer like: http://www.refresh-sf.com/yui/.
For my PHP based Drupal applications, I also compress my CSS files using smartoptimizer: http://farhadi.ir/posts/how-to-install-smartoptimizer-on-drupal.
In the end, do not forget to implement "Never expire" policy by setting far future time for your css files, so that the browser need not have to send the request for CSS again and again to the server.
