Hi Paul,
Yes am on a Powerhouse plan.
Link to the page: https://app.squarespacescheduling.com/schedule.php?owner=27699300
Basically I would like to make all backgrounds of the booking experience black and text #EBE8E1
I managed to do the calendar with the help code snippets on the help centre but not the choose your time zone and the choose your month containers.
These are the things I managed to alter:
.calendar { background-color: #000000; }
.scheduleday.activeday { color: #C9F3A9; }
.scheduleday { color: #EBE8E1; }
Really appreciate the help!
