Funny thing – when you edit wordpress templates ccs (and other CMS) in Google Chrome – often the cache glitches, and as a result, when you refresh the page changes are not visible. I did not understand what’s wrong until I refreshed the page cache (Ctrl+F5).
In other browsers (fox, for instance) it’s OK; knows when to refresh what. By the way, chrome glitches permanently in terms of caching – it can be seen in YouTube, where the bar “… begins live broadcasting” is often lit on old videos, although there is no broadcast. I wrote to google support about a year ago – they know about the problem, but so far they are not scratching.
