我的问题是关于在视频中放置导航栏和徽标，它应该是响应
它已经杀死我的时间像地狱一样。
任何人都可以请帮助我，为什么这不响应所有screens.I想要在背景和视频的视频我想在顶部的导航栏和标志在所有屏幕的中心，再加上风景模式。我尝试了最好的水平，但失败了。所以请在所有屏幕上查看并响应，有时导航栏会自动消失。

My question is about placing navbar and logo over video and it should be responsive Its already killing my time like hell. Can anyone please help me out that why this is not responsive at all screens.I want video in the background and over the video I want navbar on the top and logo in the center in the all screens plus landscape mode also. I have tried my level best but I failed. So please take a look and make it responsive in all screens , also sometimes navbar disappears automatically.
