Javascript & CSS Back To Top Button

Welcome back to another of my 30 Days Of Frontend Challenges videos. In today's frontend challenge, we're going to build an animated back to top button. We'll have the button hidden by default, but once the user starts to scroll, we'll hide it. When the user clicks it, we'll animate the page back to the top.
