Background image for specific events?

[kegami1-beep]

I want to add a background image for specific events. Example: whenever there is "Pizza Party" on the calendar, a pizza .jpg or .PNG is shown in the background of that day. Is this possible? Or at the very least show an image somewhere in the description?

Put this in /modules/MMM-CalendarExt3/MMM-CalendarExt3.css

.CX3 .cell.month_12.date_25 {
background-image: url("/modules/MMM-CalendarExt3/christmas.png");
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}

Change the month and date to the the date you need and change the png to your image
