Complete Translation or Customization?

Anyone have tip on how to translate the Booking Widget fully?
Or how to make changes in CSS to get to the goal?

Despite choosing Norwegian I still get
“Today” as a note in English inbetween Norwegian translation.
Furthermore :
“Confirm Booking” when clients are close to booking.
“Required” as Required fields

Anyone have a tip on how to fully translate, so it looks professional?

There are some changes we need to make to the new experience. In the interim I sent an email with the translations you need to modify with CSS.
