As you can see using the animate and scrollTop functions in jQuery we don’t need a plugin to create a simple scroll to top animation.

By changing the scrollTop value we can change where we want the scrollbar to land, in my case I used a value of 0 because I want it to go to the very top of our page, but if I wanted an offset of 100px I could just type 100px in the function.

So all we are really doing is animating the body of our document throughout the course of 800ms until it scrolls all the way to the top of the document.
