Pro web developer tip: always clear cache (CTRL+F5 instead of regular refresh) if a change is not immediately visible. Websites will cache a lot of things to speed up the website and save bandwith. Whenever your browser needs to request a file (usually images or CSS) it will first look in your local cache. Using CTRL+F5 clears that cache and forces the browser to retrieve the updated file from the webserver.
