jquery - 使用 jQuery 隐藏菜单，然后使用 CSS3 媒体查询重新出现

希望这应该是一个简单的，但就是不太明白。我正在制作一个小的响应式菜单，当窗口大于 800 像素宽时，它会在页面顶部显示为内联 block 。当低于此值时，导航消失并被一个切换按钮取代，单击该按钮会弹出下方和左侧的导航。

一切正常，但是代码中的一个小错误是，如果您将窗口大小调整到 800 像素以下，打开菜单然后再次关闭，然后将窗口大小调整回 800 像素以上，菜单将不再显示顶部，因为 jQuery 已将其隐藏。

是否可以更有效地重写我的媒体查询，以便任何时候将窗口大小调整到 800 像素以上时，它都能正常显示菜单？我最初写了一个小 jQuery，它不断检查 $(window).width() 是否高于 800，但这似乎是一个非常笨拙的解决方案。

谢谢!弗雷泽

最佳答案

我会说，试试:

@media screen and (min-width: 800px) {
    nav{
         display: block !important;
    }
}
