Answer 1

This should be the code. you should add a class in css as

bottomMenu.active{}

to define your styles there.

$(window).on("scroll", function() {
    if($(window).scrollTop() > 2300) {
        $(".bottomMenu").addClass("active");
    } else {
       $(".bottomMenu").removeClass("active");
    }
});

Answer 3

can you try this ?

$(document).scroll(function () {
    if(($(document).height() - $(document).scrollTop()) > 100 ) {
       $('.bottomMenu').show();
    } else {
       $('.bottomMenu').hide();
    }
});

or javascript way like

document.documentElement.scrollHeight - document.documentElement.scrollTop
