<script type="text/javascript">
//<![CDATA[
function myLength()
{
    var element = document.getElementById('fname');
    element.value = element.value.toUpperCase();
    document.getElementById('len').innerHTML = element.value.length;
}
//]]>

Use the 'style' property of HTML elements.

<script type="text/javascript">
//<![CDATA[
function myLength()
{
    var str, strColor;
    var display = document.getElementById('streng');
    var element = document.getElementById('fname');
    var leng = element.value.length;
    document.getElementById('len').innerHTML = leng;
    if(leng <= 3)
    {
        str = "Weak";
        strColor= "red";
    }
    else if(leng <= 6) 
    {
        str = "Decent";
        strColor = "orange";
    }
    else
    {
        str = "Strong";
        strColor= "green";
    }
    display.style.color = strColor;
    display.innerHTML = str;
}
//]]>
</script>
</head>
<body>
<form id="frm">
<label>Enter password:</label><input type="password" id="fname" onkeyup="myLength();" /><br /><br />
<div>length of the password is: <span id="len"></span></div><br />
<div>The password is : <span id="streng" style="font-size: 20px;"></span></div>
</form>
</body>
</html>

Also read some good tutorials so that you don't have basic queries. Start here.
