If you're site's CSS is being updated and you are not seeing your changes, or if you are experiencing other issues with viewing content you thought was updated, nine times out of ten, the problem is that you are viewing a cached version of your site.  The answer in this case is to clear your browser's cache.  Sometimes, a simple F5 (PC) will do the trick.  Other times, you will need to perform a hard reset.  Here are instructions for performing a hard reset of your cache for a number of popular browsers:
