Boa noite pessoas, já estive diversas vezes por aqui, só com dúvidas sobre linux. hoje preciso de uma explicação (na verdade uma luz). Eu copie este código na internet pois achei muito elegante. No entanto, o código parece funcional (visto na explicação de onde tirei). Mas quando coloquei para ver como ficava, ele simplesmente não funciona. Alguém poderia me dizer porque disso.
Sempre ocorre erro neste ponto do programa (em negrito).

HTML:

    <header class="header">

      <a href="#" class="logo">My Name.</a>

      <div class="bx bx-menu" id="menu-icon"></div>

      

      <nav class="navbar">

        <a href="#home" class="active">Home</a>

        <a href="#about">HOME</a>

        <a href="#education">EDUCATION</a>

        <a href="#skills">SKILLS</a>

        <a href="#contact">CONTACT</a>



        <span class="active-nav"></span>

      </nav>

    </header>


Javascript:

let menuIcon = document.querySelector('#menu-icon');

let navbar = document.querySelector('.navbar');



menuIcon.onclick = () => {

    menuIcon.classList.toggle('bx-x');

    navbar.classList.toggle('active');

}



let sections = document.querySelectorAll('section');

let navlinks = document.querySelectorAll('header nav a');



window.onscroll = () => {

    sections.forEach(sec => {

        let top = window.scrollY;

        let offset = sec.offsetTop - 100;

        let height = sec.offsetHeight;

        let id = sec.getAttribute('id');



        if(top >= offset && top < offset + height) {



            navlinks.forEach(links => {

                links.classList.remove('active');

                document.querySelector('header nav a[href*=' + id + ']').classList.add('active');

            });



            sec.classList.add('show-animate');

        }



        else {

            sec.classList.remove('show-animate');

        }

    });





    let header = document.querySelector('header')



    header.classList.toggle('sticky', window.scrollY > 100);





    menuIcon.classList.remove('bx-x');

    navbar.classList.remove('active');





    let footer = document.querySelector('footer');

    footer.classList.toggle('show-animate', this.innerHeight + this.scrollY >= document.scrollingElement.scrollHeight);

}

    O código manipula diversas classes CSS que não estão no código que enviou. Manda o CSS também para podermos rodar o código e ver o que esta de errado.

    Já te adianto que o menuIcon.onclick está funcionando, coloquei um console.log dentro e printou corretamente ao clicar no elemento na tela. Falta só o CSS.

    Calistro, boa noite.
    O <html>, parece incompleto....

    let sections = document.querySelectorAll('section');
    captura os elementos 'section', que não existem.

    A função:
    window.onscroll = () => {
    sections.forEach(sec => {
    ....
    })
    ....
    }
    Que 'pega ' o evento onscroll,
    O forEache, usa os elementos de "sections",
    bem provável que esse trecho não funcione.

    Boa noite Calistro.
    Testando aqui, o erro apresentado é referente a linha:
    let footer = document.querySelector('footer');
    Somente um "PONTO" resolveu o problema....
    let footer = document.querySelector('.footer');

    Estava 'tentando' pegar o 'elemento' footer, mas, deve "pegar" o elemento cuja classe é "footer" ....

    
Mensagem de erro no console
    
Uncaught TypeError: Cannot read properties of null (reading 'classList')
    
    at window.onscroll

    É isso....
