When I try to use the Custom CSS field on a rental calendar, instead of applying to the calendar, the CSS is printed below the iframe. I am embedding the calendar with an iframe into a WordPress (Divi) Code block, the same as I do with appointment calendars with no issue. My CSS is fine. I have tried much simpler CSS with no luck. I tried a couple of things the AI support widget suggested, like wrapping the CSS in an html <style> element, and applying the CSS to the code block in WordPress instead of the custom CSS field in GHL. Still no luck. I believe there is some kind of disconnect where the custom CSS field in GHL simply is not applying to the calendar at all.
