For the shadow effect you will have to use LAYERS. There is no built-in support for this in HTML. You will have to your DHTML for the same.

JavaScript can allow you to achieve for the results.

You may use the following fade script written by me as a start point. This script changes the background color of the page.

function makearray(n) {
    this.length = n;
    for(var i = 1; i <= n; i++)
        this[i] = 0;
    return this;
}

hexa = new makearray(16);
for(var i = 0; i < 10; i++) hexa[i] = i;
hexa[10]="a"; hexa[11]="b"; hexa[12]="c";
hexa[13]="d"; hexa[14]="e"; hexa[15]="f";

function hex(i) {
    if (i < 0)
        return "00";
    else if (i > 255)
        return "ff";
    else
        return "" + hexa[Math.floor(i/16)] + hexa[i%16];
}

function setbgColor(r, g, b) {
    var hr = hex(r); var hg = hex(g); var hb = hex(b);
    document.bgColor = "#"+hr+hg+hb;
}

function fade(sr, sg, sb, er, eg, eb, step) {
    for(var i = 0; i <= step; i++) {
        setbgColor(
        Math.floor(sr * ((step-i)/step) + er * (i/step)),
        Math.floor(sg * ((step-i)/step) + eg * (i/step)),
        Math.floor(sb * ((step-i)/step) + eb * (i/step)));
    }
}



To call this script, put this line in your page.

<script language=javascript>setTimeout("glow()",5000)</script>

> How can add shadow to a text in html :

If you don't mind targeting Internet Explorer, here is a very quick and easy way to do it:

<table style="filter: progid:DXImageTransform.Microsoft.Shadow(direction=135,color=#808080,strength=2)"><tr><td>This Text is Shadowed!</table>

(I don't know why it has to be in a TABLE tag, it just does..)

> Also how can change it's color.

You change its color by changing the "color=#808080" to whatever RGB color value you want.  There are 2 other values (direction and strength) that you can play with too to get how you like it.

It might be nicer if you used a style sheet instead of an inline style tag to accomplish this, but the idea is the same:  Use  the MS filter to add a drop shadow.

It works on images, too...

Hope That Helps,
Dex*

>>I don't know why it has to be in a TABLE tag, it just does..
I'm not sure where you're getting that info from, it certainly doesn't require a table.

It does require what's called "layout", which allows us to render css styling effects. An object with a layout is anything that is either absolutely positioned, contained in a block element, or is an inline element with a specified height or width.


<html>
<head>
<style type="text/css">
<!--
body        { font-family: Verdana, sans-serif; font-size:15px; color:#000000; font-weight:bold; }
div.bshadow { filter: progid:DXImageTransform.Microsoft.Shadow(color=#cccccc, Direction=135, Strength=4); width: 300px; }
div.rshadow { filter: progid:DXImageTransform.Microsoft.Shadow(color=#ff0000, Direction=135, Strength=4); width: 300px; color:#0000FF; }
/-->
</style>
</head>
<body>
<div class="bshadow">Black text with a black shadow.</div>
<div class="rshadow">Blue text with a red shadow.</div>
</body>
</html>

And just to complete the picture:

For a more cross-browser css implementation:
<html>
<head>
<title></title>
<style type="text/css">
<!--
h4 { position: relative; left: 1px; top: 1px; color: #999; font-family: "Times New Roman"; font-size:21px; }
.text { position: absolute; left: -2px; top: -2px; color: #000;}
//-->
</style>
</head>
<body>
<h4>A headline with a drop shadow<font color="#FFFFFF" class="text">A headline with a drop shadow</font></h4>
</body>
</html>

At some point in the future, most browsers will (should) support the CSS2 text-shadow property:
http://www.w3.org/TR/REC-CSS2/text.html#propdef-text-shadow

Safari actually supports it now in OSX 10.3 - for those of you that have it...

<html>
<head>
<style type="text/css">
<!--
p { font-family:Georgia; font-size: 18px; color: #000; text-shadow: black 0px 0px 5px;}
//-->
</style>
</head>
<body>
<p>Safari 1.1 in OS X 10.3</p>
</body>
</html>

@seanpowell:

Well, it was late when I wrote that.  What I should've said is that I couldn't get it to work with anything but a <TABLE> tag, but your explaination clears up why that is.  Thanks!
