CodePudding user response：

here is your correct code : missing ; and remove . before class in javascript code. good luck.

               const MenuIcon = document.querySelector(".hamburger-menu");
               const navbar = document.querySelector(".navbar");
               MenuIcon.addEventListener("click", () => {
                   navbar.classList.toggle("change");
               });
