bootstrap导航栏崩溃问题

标签： javascript jquery html css twitter-bootstrap

我正在开发的网站让我发疯。我有一个媒体查询来折叠导航栏，但我不知道如何更改按钮。崩溃也无法正确显示。试图改变navhar高度来补偿和尝试使用位置：相对但没有运气。

HTML 

<div class="containter-fluid" id="full-size-container">

    <nav class="navbar navbar-default navbar-inverse navbar-fixed-top" role="navigation" id="navbar">

          <span class="sr-only">Toggle Navigation</span>

}

#navbar .navbar-toggle .glyphicon{
    color:white;
}
#navbar .navbar-toggle:hover .glyphicon{
    color:white;
}

问题是：

  

折叠导航栏未显示在旋转木马上方   折叠导航栏无法从导航栏启动（您可以在折叠按钮和导航栏开始之间看到旋转木马滑动）   菜单按钮必须大1.2倍

感谢您的帮助

这通常是因为您为navbar指定了一个默认值为min-height: 50px的高度，因此当它低于768px时，它会为移动导航链接创建背景。通过设置固定的高度，它不再能够正常运行。尝试使用填充来更改导航的高度。

.navbar.navbar-inverse {
  font-size: 1.3em;
  width: 100%;
  text-transform: uppercase;
  padding: 25px 0;
  background-color: black;
  margin-bottom: 0;
}

工作示例：

body {
  background-color: black;
  background-position: center center;
  background-repeat: no-repeat;
  background-size: 100% 100%;
  margin: 0px;
  padding: 0px;
  font-family: "Open Sans";
  height: auto;
}
.navbar.navbar-inverse {
  font-size: 1.3em;
  width: 100%;
  text-transform: uppercase;
  padding: 25px 0;
  background-color: black;
  margin-bottom: 0;
}
.navbar.navbar-inverse .navbar-toggle {
  color: white;
  font-weight: bold;
  border-color: white;
}
.navbar.navbar-inverse .navbar-toggle:hover {
  color: #333;
  background-color: #ddd;
}
.navbar.navbar-inverse.navbar-toggle .glyphicon {
  color: white;
}
.navbar.navbar-inverse .navbar-toggle:hover .glyphicon {
  color: white;
}
.navbar.navbar-inverse .navbar-nav > li {
  margin-left: 10px;
  margin-right: 10px;
  font-size: 20px;
  color: blue;
}
.navbar.navbar-inverse .navbar-brand {
  padding-top: 0px;
  margin-top: -25px;
}

  width: auto;

没有小提琴/片段来测试您的代码，您可以尝试的一个观察是clearfix。

在jumbotron div上方添加以下代码，位于结尾</nav>

下方 
<div class="clearfix"></div>
