div { color: white; /* correct highlighting */ border-radius: 4px; box-shadow: 5px 5px 10px 10px #abc; transform: rotate(90deg); } -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtksourceview in Ubuntu. https://bugs.launchpad.net/bugs/877566 Title: Syntax highlighting missing for CSS 3 additions To manage notifications about this bug go to: https://bugs.launchpad.net/gtksourceview/+bug/877566/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
