Add CSS classes to distinguish sites for multi-site custom apps

Enter a site: ie master demo site. Open the Developer tools and check html tag classes Class must contain the domain name of the site replacing dots (.) with hyphens . If it has paths: double hyphen in between prefixed with url-: ie: http://foo.bar/foo/bar > url-foo-bar -foo-bar Change site and check the previous domain is not in class names but the new one is.
