如何使我的导航栏项目垂直，同时让徽标和图标保持在顶部

问题描述 投票：0回答：1

这是我第一次做一些响应式设计，我用它作为练习。但在尝试了几个小时之后，我现在很绝望。所以我有一个简单的 

Navbar
，左上角有一个徽标，中间有四个导航项，右侧有三个按钮。

当 

viewport
达到 
912px
的宽度时，我将导航项隐藏在中间。现在只剩下左侧的Logo，右侧的三个按钮被替换为汉堡菜单图标。

当我点击汉堡包

menu icon
时，导航项应该出现并垂直堆叠在徽标和菜单图标下方。但它们只是出现在徽标和菜单之间。目前我还没有经验，无法解决这个问题。所以我恳请帮助。

这不是最干净的方法，但它可以为您提供如何操作的指导。 我在这里还使用了一些变量只是为了记住它们，你应该在你的研究/示例中更多地使用它们。

            const burgerMenu = document.getElementById("burger-menu");
            const logo = document.getElementById("icon-logo");
            const navUl = document.querySelector("nav ul");

            function toggleMenu() {
                toggleLogo();
                toggleBurgerMenuIcon();
                toggleNavVisibility();
            }

            function toggleLogo() {
                    if (logo.src.includes("logo-small.svg")) {
                        logo.src = "../images/logo-filled.svg";
                    } else {
                        logo.src = "../images/logo-small.svg";
                    }
            }

            function toggleBurgerMenuIcon() {
                if (burgerMenu.innerHTML === "☰") {
                    burgerMenu.innerHTML = "✖";
                } else {
                    burgerMenu.innerHTML = "☰";
                }
            }

            function toggleNavVisibility() {
                navUl.classList.toggle("nav-visible");
            }

            burgerMenu.addEventListener("click", toggleMenu);
