This is a small trick I've been using on a number of sites where far expiration dates have been set on the server to improve browsing performance.
Basically if you often do any changes to your CSS (like me) the old version of the file will normally be served to your visitors as the cache expiration header is set to a far future time.
To remedy this we need to add a parameter to CSS file URL that will make it distinct every time you change it.
