Hi, could you please help me with Css to add background colour to  to the event text in calendar. We have 3 spots each day and would like to show customers if the spot is available or booked.

Also we would like to remove the click through to events. I

t should look just like that and should be  visible (minimum colours) on mobile.

Thank you!!!!

}

    color: white !important;
    pointer-events: none;
}
