Happy to see you on the forum, @EXEC!
Hmm, this is really strange, I’ve just checked the CSS code and it worked perfectly fine for me. Could you please send me the link to the page with the widget in question? I’ll be happy to check it on my end, too.
I agree that it would be a great option to implement, and we even have a similar request in our Wishlist: Choose the pages on which the badge appears Desktop / Mobile. Feel free to vote for it to follow the updates
