addveventlistener不能处理768px以上的媒体查询

标签： javascript html

我在firefox 49和chrome 63上尝试过这个网站，同样的问题，如果我点击每个支架[翻转卡]，它可以在iphone4，galaxy 5和iphone 8上运行，使用chrome，但是，经过几次尝试，如果我将方向从640px切换到320px，纵向视图，顶部翻转卡将无法立即工作，而是我必须等待30秒，然后它将工作..上述768px没有卡工作.... / p>

。问题来自导航栏[#nav_bar]被设置为绝对值，高度设置为100％，z-index为3，当切换且不透明度为1时，我可以看到它覆盖翻转卡表面积，我已经将nav_bar的高度更改为50％，70％它仍然会覆盖翻转卡的上半部分。  现在一切都运转良好，动画没有引起任何问题，很多不是Shilly，为了解决这个问题的方向......
