Which CSS property defines the floating notification background?

[samwcoulter]

The background of all the notifications when they appear (floating - not in the notification center) is completely transparent. I can't figure out which CSS style property to change to fix it.

Here is my style sheet:
style.css

Hi!

The .notification-background css class handles it.

.notification-background {
  background: red;
  box-shadow: none;
  border-radius: 15px;
}
