const navbar = document.querySelector("nav#navbar");
const close = document.querySelector(".close");
menu.addEventListener("click", function () {
  navbar.style.display = "block";
  navbar.style.bottom = "-10px";
  navbar.style.transition = "bottom .3s ease";
  menu.style.display = "none";
  close.style.display = "block";
});

close.addEventListener("click", function () {
  close.style.display = "none";
  navbar.style.display = "none";
  menu.style.display = "block";
});

const listAbout = document.querySelector(".listAbout");
const listServices = document.querySelector(".listServices");
const listHire = document.querySelector(".listHire");
function viewport() {
  if (screen.width < 426 || screen.width < 375 || screen.width < 320) {
    listHire.innerHTML = `<a href="#contact"><i class="ri-suitcase-fill"></i></a>`;
    listServices.innerHTML = `<a href="#services"><i class="ri-service-line"></i></a>`;
    listAbout.innerHTML = `<a href="#about"><i class="ri-question-fill"></i></a>`;

    listHire.style.color = "#fff";
    listServices.style.color = "#fff";
    listAbout.style.color = "#fff";

    listHire.style.fontSize = "19px";
    listServices.style.fontSize = "19px";
    listAbout.style.fontSize = "19px";

    listHire.style.transform = "rotate(-90deg)";
