  • At last, save your template and give it a view!
[success headline=Success]Congratulations! You have added this feature to your blog successfully. But if you want to give it permission to load fastly, then add it below ‘<body>’ tag. [/success]

UPDATE: We have found another script which is made of jQuery and is very minimalistic and impressive. Instead of the above script, you can use this code which would not much affect your blog's loading speed:
<script type='text/javascript'>
      //<![CDATA[
      !function(e){jQuery.scrollSpeed=function(n,o){var t=e(document),i=e(window),l=e("html, body"),r=i.height(),u=0,a=!1;return window.navigator.msPointerEnabled?!1:void i.on("mousewheel DOMMouseScroll",function(e){return a=!0,(e.originalEvent.wheelDeltaY<0||e.originalEvent.detail>0)&&(u=u+r>=t.height()?u:u+=n),(e.originalEvent.wheelDeltaY>0||e.originalEvent.detail<0)&&(u=0>=u?0:u-=n),l.stop().animate({scrollTop:u},o,"default",function(){a=!1}),!1}).on("scroll",function(){a||(u=i.scrollTop())}).on("resize",function(){r=i.height()})},jQuery.easing["default"]=function(e,n,o,t,i){return-t*((n=n/i-1)*n*n*n-1)+o}}(jQuery);
      $(function() {  
        jQuery.scrollSpeed(100, 800);
      });
      //]]>
</script>
