如何为移动设备创建汉堡菜单？

汉堡包按钮是放置在网页用户界面上角的按钮。汉堡包按钮可切换屏幕上的导航菜单栏。与此窗口小部件相关联的图标(由三个水平条组成)也称为折叠菜单图标。

我们将创建：

• 使用html，CSS和JavaScript的汉堡包菜单用于移动设备
• 使用Bootstrap的汉堡菜单

在移动设备上使用html，CSS和JavaScript的Hamburger Menu：我们将编写自己的所有HTML和CSS，并添加一些JavaScript来处理点击事件。基本方法是将导航栏的可见性标记为隐藏。当用户单击该图标时，JavaScript将从隐藏状态中删除可见性。

        function gfgMenu() {
            const GFG = document.querySelector('.links');
  
            if (GFG.style.display === "none") {
                GFG.style.display = "block";
            }
            else {
                GFG.style.display = "none";
            }
        }
    

  

输出：

使用Bootstrap的Hamburger Menu：在这种方法中，我们将使用Bootstrap设计页面，并且JavaScript的工作与上述方法相同。
