How to Add Percentage Value to a Scrollbar in Blogger
We have already shown you a way through which you can customize your Scrollbar using Web toolkit. Recently, one of our users asked us how to add percentage value to a Scrollbar in Blogger? It basically shows you the percentage of a page while scrolling. It might turn out to be extremely useful for your visitors to find out how much page they have scrolled, or how much content is left to be read. In this article, we will show you How to Add Percentage Value to a Scrollbar in Bloggers.
Note: You can check out the demo of this widget Here (Tip: Make sure you scroll up or down the page to see the percentage along the scrollbar). 

The First thing you need to do is to login into your Google account making sure that your blogs are hosted on that particular account. Now go to Blogger Dashboard and select the blog in which you would like to add Percentage Value to a Scrollbar. Go to Template >> Edit HTML and search for the ]]></b:skin> tag. Once you have found the ]]></b:skin> tag successfully, just above it paste the following CSS code.

#scroll {
display: none;
position: fixed;
top: 0;
right: 20px;
z-index: 500;
padding: 3px 8px;
background-color: #2187e7;
color: #fff;
border-radius: 3px;
#scroll:after {
content: ” ”;
position: absolute;
top: 50%;
right: -8px;
height: 0;
width: 0;
margin-top: -4px;
border: 4px solid transparent;
border-left-color: #2187e7;

After adding the CSS coding, search for the ending </head> tag and right after it paste the following code. (Tip: Make sure you paste the code between the ending </head> and opening <body> head tag.

<div id='scroll'></div>

Lastly, search for the ending </body> tag and just above it paste the following JavaScript code. This is the code which will ensure that your scrollbar shows the accurate percentage upon scrolling up or down the page. Once everything is done, save the template by pressing “Save Template” Button available on the top right corner of your screen.

<script type='text/javascript'>
var scrollTimer = null;
$(window).scroll(function() {
var viewportHeight = $(this).height(),
scrollbarHeight = viewportHeight / $(document).height() * viewportHeight,
progress = $(this).scrollTop() / ($(document).height() - viewportHeight),
distance = progress * (viewportHeight - scrollbarHeight) + scrollbarHeight / 2 - $('#scroll').height() / 2;
.css('top', distance)
.text(' (' + Math.round(progress * 100) + '%)')
if (scrollTimer !== null) {
scrollTimer = setTimeout(function() {
}, 1500);
