Node.js chat app append styled text

I made a chat app with node.js where the client enters in a username and then can send messages. It appends the message in a

<ul>
for the other users to see: "username: message". I wanted to make the username bold and blue. How can it be done with the least amount of code?

HTML (without style)

<!doctype html>


<html>


<head>

<title>Lucas Chat</title>


</head>



<body>
<div id="top">
<h1>Welcome to the chat!</h1>
<br>
<p>Enter in a nickname and a message to get started</p>
<br>
<p id="drop">Scroll up or down to view newer/older messages</p>

</div>

<ul id="messages">







</ul>


<form action="">

<input id="u" autocomplete="off" placeholder="Nickname"/><input id="m" autocomplete="off" placeholder="Message"/><button>Send</button>
</form>



<script src="https://cdn.socket.io/socket.io-1.2.0.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>
var socket = io();
$('form').submit(function(){

if ($('#m').val() != '' && $('#u').val() != '') {

socket.emit('send message', {msg:$('#m').val(),user:$('#u').val()});
$('#u').css("display", "none")
$('#m').css("width", "90%")
$("#u").css("box-shadow", "0px 0px 0px rgba(0, 0, 0, 0)")
$("#m").css("box-shadow", "0px 0px 0px rgba(0, 0, 0, 0)")
$('#m').val('');

} else if ($('#u').val() === '' && $('#m').val() === '') {
$("#u").css("box-shadow", "0px 0px 15px #ff8989")
$("#m").css("box-shadow", "0px 0px 15px #ff8989")
} else if ($('#u').val() === '' && $('#m').val() != '') {
$("#u").css("box-shadow", "0px 0px 15px #ff8989")
$("#m").css("box-shadow", "0px 0px 0px rgba(0, 0, 0, 0)")
} else if ($('#m').val() === '' && $('#u').val() != '') {
$("#m").css("box-shadow", "0px 0px 15px #ff8989")
$("#u").css("box-shadow", "0px 0px 0px rgba(0, 0, 0, 0)")
}

return false;
});
socket.on('receive message', function(msg){
$('#messages').append($('<li>').html(msg));
});
</script>



</body>
</html>


JS

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var peopleCount = 0;

app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){

peopleCount++

console.log('a user connected | connections: ' + peopleCount)

socket.on('disconnect', function(){

peopleCount--

console.log('a user disconnected | connections: ' + peopleCount)

});
});


io.on('connection', function(socket){
socket.on('send message', function(data){
io.emit('receive message', data.user + ': ' + data.msg);
});
});

http.listen(3000, function(){
console.log('listening on *:3000');
});
