<!-- Cliproll CSS Auto-Scroll customizing by BigBadWolf

Please note: I am including only the HTML basics in this page so you can
see how it works. If you'd like to see the naked basics of what to include,

Big props to EricW at clipmarks for helping me get some of this nailed down!

You can copy and paste this entire document minus a couple of lines and paste it into yours.
See the descriptions below.

<!-- Leave the <html> and <head> out when copying -->
<html>
<head>

<!-- This is the Dynamic Drive DHTML include file that handles the scrolling. I keep it in a directory
called "js" but you can put it anywhere you like just make sure to change the path. -->
<script src="js/jquery.js" type="text/javascript"></script>

<!-- You can either embed the CSS styles in your document somewhere inbetween the <head> </head>
statements or include them in an external style sheet. Leave out the <style type="text/css">
if you put it into an external sheet. -->

<style type="text/css">

/* .Clipmarks - Note that this style must be included here unless you are using external style sheets.
This sets the style for the entire clipmarks div. As it is, I set the background color, border style
and width of the div. You will see later why I am setting a width. */

.Clipmarks {
background-color: #FFFFFF; /* sets the background color for the whole cliproll */
border: thin solid #FFCC33; /* puts a border around the entire cliproll */
width: 474x; /* sets the width of the cliproll div */
}

</style>

<!-- Leave this </head> out when copying -->
</head>

<!-- Leave this <body> out when copying and paste everything below someplace between
your <body> and </body> tags -->
<body>

<!-- Here is the actual div that contains the cliproll. Copy and paste your cliproll into the line between the <div> and </div>
(the line that begins "<script type="text/javascript" src="http://clipmarks.com/feed/" is your cliproll. -->

<div class="Clipmarks" id="Clipmarks" style="width:570px; height:170px; z-index:1; left: 30px; top: 24px;">

<!-- This starts the scripting that sets up the scrolling. Set the width to -6 or so pixels less than above and the
height as the same number. -->

<script type="text/javascript">
