How to Add a Smooth Scrolling "Back To Top" Button in Blogger

Finally yet another exciting trick to create a smooth scroll to top button for BlogSpot blogs. We designed and released many buttons and tutorials on back to top/bottom buttons but they were all static and had no fade out effects and smooth scroll effects. Luckily we just discovered a cool jquery script that does all the work. A back to top button is crucial for a blog or site because visitors enjoy easy site navigation so this button will provide them with this ease. We have kept the installation process a one step process. Please see this button in action towards the bottom right corner of this blog.The best thing about this button is that it appears only when the user scrolls down the page and disappears as he scrolls up.
