FancyLayouts notifications background

Flow
1

Hi,
I’m having some issues trying to customize fancy notifications background color.

The style I’m using is the following.


.tray-notification {
    background-color: rgba(255,255,255,1.0) !important;
}

.tray-notification:hover {
    background-color: rgba(255,255,255,1.0) !important;
}

.tray-notification .fancy-notif-title {
	color: #000000 !important;
}

.tray-notification .fancy-notif-desc {
	color: #000000 !important;
}

The background actually change to white, but it seems that some 0.5 alpha opacity is still there.
Unfortunately I’m not able to find it with firebug.
Anyone experienced a similar problem?
