Volumio project with extra hardware buttons

Based on this post I tweaked my display CSS to hide the volume control which is useless with the digital output:

Here’s what I added to the end of app-e831b7a181.css:

@media (min-width: 800px) and (max-width:800px) and (min-height: 480px) and (max-height: 480px)
{
/* hide scrollbar on playback screen */
div#contentWrapper.playback { overflow-y: hidden !important; }

/* hide multi-room */
multi-room-dock {
    display:none;
}

/* wider scrollbars */
::-webkit-scrollbar{
    width: 30px;
    height: 30px;
}

.knobWrapper {
    margin-bottom: 4px;
}

#playbackPanelWrapper #rightPanel {
	display:none;
}

#trackInfo #trackDetails
{
	text-align:center;
	margin-left: -433px;
	width:400px;
	height: 200px;
	overflow:  visible;
}

#playbackPanelWrapper #leftPanel {
	float: left;
	width: 50%
}

#playbackPanelWrapper #centerPanel {
	float: left;
	width: 50%
}

#trackInfo {
	position: relative;
	float: left;
	width: 100%;
	min-height: 1px;
	padding-left: 0px;
	padding-right: 0px;
	text-align: right;
	margin-top: 28px;
	line-height: 1.3;
	margin-left: 25px;
}

#trackInfo img {
	width: 100%;
	margin: 0;
	max-width: 380px;
	max-height: 320px;
	border: 0px;
	margin-top: -200px;
	object-fit:contain;
}
}
