是否可以修复该栏，以便在滚动期间始终可见？
我需要在滚动过程中修复导航和第一个顶栏（带徽标的那个）。
HTML code：
<!--*-*-*-*-*-*-*-*-*-*- Start Logo Bar *-*-*-*-*-*-*-*-*-*-->
<div class="container-fluid logo-bar">
<div class="container">
<div class="row">
<div class="col-md-9">
<div class="row">
<!--======= Text =========-->
<div class="col-md-4 logo_bar_icons">
<h2 class="first-text"><b>Wohnen</b>,<br>wie es <b>gefällt.</b></h2>
</div>
</div>
</div>
<!--======= Logo =========-->
<div class="col-md-3">
<a href="index.html">
<img src="img/logo_2.png" class="img-responsive" alt="Logo" id="" />
</a>
</div>
</div>
</div>
</div>
<!--*-*-*-*-*-*-*-*-*-*- End Logo Bar *-*-*-*-*-*-*-*-*-*-->

在bootstrap中很容易。您需要做的就是在第一个nav元素中添加一个.navbar-fixed-top类。该类是在bootstrap css中预定义的，它添加如下：
.navbar-fixed-top {
position: fixed;
right: 0;
left: 0;
top: 0;
z-index: 1030;
}
所以你看，它始终位于文件顶部（顶部：0;），并固定在该位置（位置：固定;）。

这是直接来自getbootstrap.com，是您正在寻找的。
