Stylish tags doesn’t work — and mostly because of lazy admins and content creators They don’t clean breaking news!!!111!1!! tags and quite soon everything is polluted with old news advertizing breaking one.
And that’s why such tag/announcement must work under timer.
We have right now one active topic about mobiles. Such tag or sketch of OP just doesn’t work. There is not enought space. Background color, perhaps. But hey… we have old netscape trick: blinking colors
Perhaps if a breaking news type would be lifted on the top and keeped separately? A bit like what we can do with carousels?
