Floating back button is fantastic and it's most useful button for when website page size is too much large and user want to scroll at the top when it's at bottom of the page. It's very useful to make user friendly website.

This type of button is most useful when we have a large amount of content in a single page that time we need this type of button going at the top of the page.

To make better interface and responsive button, we need to use css and jQuery to create this button.

When page is scroll down, then button automatically display on the page and when click on button then page will scroll and move on top of the page.
