My MagicMirror isnt a mirror at all - its a display that is on in my kitchen. It has two modes - normal - shown below, which shows calendar, what is currently playing on my Sonos speaker in my kitchen, weather, and headlines.

and also a ‘party’ mode, where all that other info is hidden, and only shows me and my guests what music is playing

Happy to share my custom CSS code with anyone that wants to see this.

thanks - Uploaded the code here.

@yawns Ive uploaded my version of calendar.js to github. access it here : https://github.com/dinkybluebug/MMM-CustomCSSv2

It has amended javascript for calendar to show day of week and time.

@schlachtkreuzer6 In Nodehelper.js - I changed lines 104-117. I didnt need the option of monitor on and off, as I have a PIR sensor attached to my display.

if (query.action === 'MONITORON')
		{
			exec('cp ../MagicMirror/css/party_custom.css ../MagicMirror/css/custom.css', opts, function(error, stdout, stderr){ self.checkForExecError(error, stdout, stderr, res); });
			exec('cp ../MagicMirror/config/party_config.js ../MagicMirror/config/config.js', opts, function(error, stdout, stderr){ self.checkForExecError(error, stdout, stderr, res); });
			exec('pm2 restart mm', opts, function(error, stdout, stderr){ self.checkForExecError(error, stdout, stderr, res); });
			return true;
		}
		if (query.action === 'MONITOROFF')
		{
			exec('cp ../MagicMirror/css/normal_custom.css ../MagicMirror/css/custom.css', opts, function(error, stdout, stderr){ self.checkForExecError(error, stdout, stderr, res); });
			exec('cp ../MagicMirror/config/normal_config.js ../MagicMirror/config/config.js', opts, function(error, stdout, stderr){ self.checkForExecError(error, stdout, stderr, res); });
			exec('pm2 restart mm', opts, function(error, stdout, stderr){ self.checkForExecError(error, stdout, stderr, res); });
			return true;
		}

As the functions had changed, I then changed the text displayed in the app , by changing the text in the remote.html file. Line 80- 87

               <div id="monitor-on-button" class="menu-element button main-menu">
                    <span class="fa fa-fw fa-glass" aria-hidden="true"></span>
                    <span class="text">Party Mode</span>
                </div>
                <div id="monitor-off-button" class="menu-element button main-menu">
                    <span class="fa fa-fw fa-calendar" aria-hidden="true"></span>
                     <span class="text">Calendar Mode</span>
                </div>```

I had installed the remote control module too, and tweaked it slightly, so I can move between Normal and Party mode, instead of using bash scripts via SHH
