我遇到的问题是当我点击一个菜单项时它仍然是打开的，因为它是一个带有锚链接的单页网站。单击任何菜单项链接关闭菜单的最佳方法是什么？使用javascript删除菜单onclick不是一个好选择，因为X还需要恢复到汉堡包，如果你使用这种方法它不会。任何帮助表示感谢，提前谢谢！
答案 0 :(得分：1)
可以在不破坏结束图标行为的情况下添加一点JavaScript。
查看下面的修改后的代码段，在点击菜单链接时添加eventListener时，只需取消选中与切换菜单汉堡图标相对应的输入字段：
var menu = document.getElementById('menu');
var closeIcon = document.getElementById("closeIcon");
menu.addEventListener('click', handleMenuClick);
function handleMenuClick(event) {
if (event.target instanceof HTMLAnchorElement) {
closeIcon.checked = false;
}

注意，我还修改了菜单列表元素的语义，将元素放入li元素中，而不是像之前那样反之。另外，在菜单中添加display: block;元素，使其成为全宽并可正确点击。
然而，这不应影响菜单的外观。
注意 如果您想知道是否可以使用纯CSS唯一解决方案。 理论上，您可以尝试通过单击菜单链接取消选中汉堡图标输入字段。您可以尝试使用具有相同名称的无线电输入，以便它们相互切换。
不幸的是，有两件事情与此相反：
答案 1 :(得分：0)
您可以使用Jquery来切换菜单：
Open: $('#menuToggle input').prop( "checked" ,true);
Close: $('#menuToggle input').prop( "checked" ,false);
