Here's one example that uses strictly CSS to horizontally auto-scroll as an area with a fixed width is populated. No scroll bars are used or rendered. A few things to note here:

  • Your question is a bit ambiguous. When you say you want it to auto-scroll, do you mean that you want the content to scroll by as it's added to the div? Do you mean you want it to repeatedly scroll over the same text? Or perhaps something else? I'm assuming here that you're requesting the first option.

  • The scrolling here uses no JavaScript, but of course some script is needed to populate the div that's being scrolled.

  • I've only tested this in Firefox and Chrome.

<html>
<head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
        <style type="text/css">
                #scrollbox{
                        display: inline-block;
                        width: 16em;
                        overflow: hidden;
                        border: 1px solid #F00;
                }   
                #scrollcontent{
                        float:right;
                        white-space: nowrap;
                }   
        </style>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
        <script type="text/javascript">
                var idx = 0;
                $(document).ready(function(){
                        setInterval(function(){
                                idx++;
                                $('#scrollcontent').append('foo_' + idx + " ");
                        }, 200);
                })
        </script>
</head>
<body>
        <span id="scrollbox">
                <span id="scrollcontent"></span>
        </span>
</body>
</html>

That works nicely as long as you're adding text to the div and only wish for it to scroll rightwards as the text is added. If you want it to automatically scroll left and right, then you'll need JavaScript to automatically zig-zag the position of "#scrollcontent". You would need an algorithm that gets the width of the parent span ("#scrollbox" in this case), subtracts that from the width of the child span ("#scrollcontent") and oscillates a number between zero and the result of that subtraction. The x position of the child span would be set to the negative of that number. Note that you would need to give "scrollcontent" an absolute position, and remove the float: right attribute. You would also need to specify the position attribute for "scrollbox", otherwise the absolute position of scrollcontent would be relative the next parent that does have the positioning explicitly defined, rather than scrollbox itself.

Here is the code for static text, you need to give the width according to text inside the div:

CSS:

.divcon-outer{
width:143px;

}
.divcon{
margin:0px;
padding:0px;
max-height:45px;
width:auto;
font:bold 9px Verdana, Geneva, sans-serif;
line-height:30px;
color:#000;
background-image:url(../images/glass_bg.png);
background-repeat:repeat-x;
display:block;
overflow-x: auto;
overflow-y: hidden;

}
.divcon p{
min-width:200px;
max-width:50000px;
margin:0;
padding:0;
}

HTML:

<div class="divcon-outer">
<div class="divcon"><p>I have div with fixed width.I want to auto scroll(lefta nd right:Hirizontal direction) the text if content of div is more than div width.How can i do this thought css or jquery.Currently div has a class like this..</p></div></div>

Add 

overflow: auto; /* scroll bars appear, only when they are needed */

or 

overflow: scroll; /* scroll bars appear (both horizontal and vertical, even when not needed */

There are also other ways of coding overflow, especially if you want a specific scroll bar to appear. Although, these are not widely supported by older browsers (IE8 and earlier).

overflow-x: scroll; /* only horizontal scroll bar */
overflow-y: scroll; /* only vertical scroll bar */

One Simple method will be adding overflow in the CSS class:

overflow: scroll;

This will make div scrollable both in horizontal and vertical.

If you want scroll in one direction only, then you should try:

overflow-y:scroll; // For vertical scroll bar

And

overflow-x:scroll; // For horizontal scroll bar

you can have like this

for giving horizontal scroll

overflow-x:scroll;

for giving vertical scroll

overflow-y:scroll;

for giving scroll on both side overflow:scroll;

From above css default scroll will come it will not depend on the content size

To make it depend on the content size make scroll --> auto
