Upcoming events Enfold/The Events Calendar

It’s been driving me crazy trying to figure out how to target the background color in the events calendar upcoming events widgets. You can see on the front page it’s just white. How can I make it a different color or target it?
I tried this in the custom css in the Enfold folder, but it has no effect.

.av-upcoming-event-data {
	background-color: red !important;
}
