It's mostly a browser issue - the site's CSS is stored your browser so it doesn't have to download it every time you visit a page, but that caching causes problems in situations like this where the new CSS conflicts with the old. You'll either have to manually clear your cache and refresh, or (probably what you did) just wait for your browser to make the change. -- 09:25, October 24, 2016 (UTC)
