JavaScript

$(document).ready(function(){
    // scroll elementos Menu
    var aboutme = $('#about').offset().top,
        project = $('#jobs').offset().top,
        contactme = $('#contact').offset().top;

    $('#btn-about').on('click', function(e){
        e.preventDefault();
        $('html, body').animate({
            scrollTop: 240
        }, 500);
    });

    $('#btn-jobs').on('click', function(e){
        e.preventDefault();
        $('html, body').animate({
            scrollTop: project
        }, 500);
    });

    $('#btn-contact').on('click', function(e){
        e.preventDefault();
        $('html, body').animate({
            scrollTop: contactme
        }, 500);
    });

});

What I have tried:

Due to the depreciation of JQuery. They would be so kind to help you migrate, I'm very clueless
