Actually, this scrollbar percentage is not an important feature for a blog. But it never hurts to try, it was depending on the taste of each.
By adding this percentage not only as a blog ornament but visitors will be able to see what percentage of pages he has a scroll if it has reached the bottom of the page then the percentage value will be 100%.
How to apply it is quite easy, please follow the following simple steps:
First, keep the code below just above ]]></b:skin>or</style>
#scroll {
display:none;
position:fixed;
top:0;
right:15px;
z-index:500;
padding:3px 8px;
background-color:#369fcf;
color:#fff;
border-radius:3px;
font-size:14px;
}
#scroll:after {
content: " ";
position: absolute;
top:50%;
right:-10px;
height:0;
width:0;
margin-top:-6px;
border:6px solid transparent;
border-left-color:#369fcf;
}
Next, save the caller code below </head>
<div id='scroll'></div>
Keep the code below just above </body>
<script type='text/javascript'>
//<![CDATA[
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;
$('#scroll')
.css('top', distance)
.text(' (' + Math.round(progress * 100) + '%)')
.fadeIn(600);
if (scrollTimer !== null) {
clearTimeout(scrollTimer);
}
scrollTimer = setTimeout(function() {
$('#scroll').fadeOut(600);
}, 1000);
});
//]]>
</script>
Then save the Template.
If the steps you are doing is not wrong, then your blog should already have a percentage in addition to the scrollbar.
Quite easy is not it. Good luck.
