在浏览器移动屏幕尺寸中切换导航图标将使导航列表项在将浏览器屏幕调整为大尺寸时消失

Question

你好，我目前的问题是，当页面最初加载时，导航工作正常，并且在浏览器放大时正常显示，但是当将浏览器 window 重新调整为较小的尺寸时，切换导航菜单图标工作但是然而

a) 如果移动菜单保持打开状态，则重新调整较大的 Web 浏览器屏幕中的布局要么 b) 如果移动菜单关闭，导航项将完全消失

重新调整浏览器时 window 回到更大的屏幕尺寸。

我试图将 display:block 属性放在较大的媒体查询中适当的 class 选择器下。它没有填充任何导航列表项目，我保留了 display:flex 属性因为这就是我希望在更大的布局中格式化导航列表项目的方式。

我目前正在使用我在 css-tricks 上找到的一个简单脚本，但我愿意接受其他建议来解决想要简单地隐藏和显示导航菜单而不影响其他菜单的问题大型媒体查询中的布局。

当切换到更大的视口时，您需要将 #nav-list 的显示属性设置回 flex，因为当切换移动导航时它已经被覆盖。

@media screen and (min-width: 760px){
  #nav-list {
    display: flex!important;
  }
}

在浏览器移动屏幕尺寸中切换导航图标将使导航列表项在将浏览器屏幕调整为大尺寸时消失

Toggling nav icon in browser mobile screen size will make nav-list-items dissapear when readjusting browser screen to large size
