Answer 1

I am using this, This is also simple

$(document).ready(function(e) {
var a = 400,
t = 1200,
l = 700,
s = e(".scrool-top");
e(window).scroll(function() {
e(this).scrollTop() > a ? s.addClass("scrool-is-visible") : s.removeClass("scrool-is-visible scrool-fade-out"), e(this).scrollTop() > t && s.addClass("scrool-fade-out")
}), s.on("click", function(a) {
a.preventDefault(), e("body,html").animate({
scrollTop: 0
}, l)
})
})
