To get a peek on how it works...click here..

A reminder:
  • The CSS is what u paste between <style type="text/css"> and </style>
  • The HTML is what you paste between </style> and </body>
*Paste the following between the tags <head> and <style type="text/css>
<link href="http://static.tumblr.com/1f1tzta/Drsme9t4s/preview.css" rel="stylesheet" type="text/css" />
* To make things happen, u've gotta change ur post-body CSS tags to #content(for CSS) and <div id="content"> (for html)
For example, before the tag <blogger>, replace any existing tag before it or simply add the following code:
<div id="content">

as for the content's CSS, u've gotta paste the following:
#content {
position:relative;
margin:0 auto;
width: 400px;
height:560px;
left:4%;
top:0px;
-webkit-box-sizing:border-box;

-moz-box-sizing:border-box;

box-sizing:border-box;

overflow:auto;
background:transparent;
}

*you can edit those texts in pink.

Now, add the following script right before the tag </body>:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script>!window.jQuery && document.write(unescape('%3Cscript src="http://static.tumblr.com/1f1tzta/dX9m986fz/jquery-1.7.2.min.js"%3E%3C/script%3E'))</script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>!window.jQuery.ui && document.write(unescape('%3Cscript src="http://static.tumblr.com/1f1tzta/gacm986gu/jquery-ui-1.8.21.custom.min.js"%3E%3C/script%3E'))</script>
<script src="http://static.tumblr.com/1f1tzta/KtCm986fe/jquery.mousewheel.min.js"></script>
<script src="http://static.tumblr.com/1f1tzta/QPIm986ex/jquery.mcustomscrollbar.min.js"></script>
<script>
(function($){
$(window).load(function(){
$("#content").mCustomScrollbar({
scrollButtons:{
enable:true
}
});
});
})(jQuery);
</script>
