## ❓ Frequently Asked Questions

**Q: Why are all dates grayed out in the calendar?**
A: By default, no dates are available. You must go to **Settings > GRT Booking** and add an "Available Date Range" for the dates you want to be bookable.

**Q: Can I style the form?**
A: Absolutely! The plugin uses `assets/css/grt-booking.css`. You can easily override these styles in your theme's custom CSS or child theme.
