The Scroll Buttons component consists of two scroll buttons, one for scrolling up and the other for scrolling down, and can be placed at a comfortable position on the webpage.
You need to set the component fixed position type for it to work.
When you paste the component, by default it scrolls by 300px per click. You need to customize the values to acheive smoothness and make it work like demo.
Just copy, paste and customize as you like.
