javascript - 为什么我的非 Canvas 菜单在打开时将我的固定 div 推出框架?

我使用 Pushy off-canvas menu对于我的网站,它工作得很好,但它给我固定的 div header 带来了麻烦。当我向下滚动页面时,标题会完美地贴在顶部,但是一旦我打开 Canvas 外菜单,我的标题就会消失?当我关闭我的 Canvas 外菜单时,它会突然回来。看起来很奇怪。

您可以查看(密码笔)live demo of my problem, here.或者直接运行下面的代码片段。

我希望它在 Canvas 外菜单打开时保持可见。帮助将不胜感激。
提前致谢。

最佳答案

有一个关闭的issue关于那个爱出风头的:

The trick is to have any fixed position (like a fixed header) elements outside of the container div. See the demo.html for examples.

在您的案例中,将 .header 移到 #container 之外是可行的。

如果您对造成这种情况的原因感兴趣,请参阅 this answer .
