固定Bootstrap导航栏以768 x 1024视图消失(Fixed Bootstrap navbar disappearing with 768 x 1024 view)

 我下载了自举AZY响应1页模板，无法使固定导航栏保持在屏幕顶部768 x 1024（iPad - 人像）分辨率。 从240 x 320到1024 x 768，它仍然固定在所有其他位置的顶部。 
 
 我创造了一个小提琴： http ： //jsfiddle.net/B2sw6/ 
 
 我尝试使用它但它不起作用： 
 
.navbar-fixed-top {
    position: fixed;
    right: 0;
    left: 0;
    z-index: 1030;
    top: 0;
}
 
 如果将中心分隔条拖到约。 768px宽度您将看到黑色导航栏与页面的其余部分向上滚动而不是保留在顶部。 
 
 有没有人有任何关于如何更新CSS以纠正此问题的提示？ 

I downloaded the bootstrap AZY responsive 1 page template and cannot get the fixed navbar to stay at the top of the screen for 768 x 1024 (iPad - Portrait) resolution. It remains fixed at the top for all others from 240 x 320 to 1024 x 768.
 
I've created a fiddle: http://jsfiddle.net/B2sw6/
 
I tried using this but it didn't work:
 
.navbar-fixed-top {
    position: fixed;
    right: 0;
    left: 0;
    z-index: 1030;
    top: 0;
}
 
If you drag the center divider bar across to approx. 768px width you will see the black navbar scrolls up with the rest of the page instead of remaining in place at the top. 
 
Does anyone have any hints on how to update the CSS to correct this?
