我在旋转木马下使用导航栏和子弹。到达那里之后，我的subnav应该被修复。它是固定的，但内容正在跳跃。 如果我只使用上面的容器我会找到一个解决方案，但它不适合我，所以它仍在跳... 我已经看到了一些解决方案，但没有得到它.. 那我在做什么呢？

通常当网站从词缀跳转时，它是因为标题变为位置固定并离开布局并位于内容本身的顶部。网站的其余部分＆＃34;跳跃＆＃34;抬高标题的高度。
您可以做的一件事就是将导航栏包装在包装器中，并为导航栏包装器指定导航的高度。
<div class="navbar-wrapper">
<nav class="navbar navbar-inverse navbar-static-top navtop">
<!-- the rest of your nav code is here -->
</nav>
</div>
和css
.navbar-wrapper { height:60px; } /* or whatever the height of the nav is */
您可以使用浏览器检查器或猜测直到跳转消失来找到导航的高度。
这是你的Jsfiddle，清理了一下以便它可以正常工作。
