Bootstrap Navbar在小屏幕上占用了太多空間

Question

我正在使用bootstrap 3創建一個響應式網站。折疊的導航欄存在問題，其中正常高度（即一個導航鏈接項目的高度）代替了它的正常高度（它占用了所有導航鏈接項目的總高度）。 這是我在說的http://tinyurl.com/pr4hae5的屏幕截圖

這是我的HTML，尚未覆蓋任何默認的Bootstrap CSS。

<!-- Static navbar -->
  <nav class="navbar navbar-inverse">
    <div class="container-fluid">
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>

<!-- Bootstrap core JavaScript
================================================== -->
<!-- Placed at the end of the document so the pages load faster -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

一切正常...只需將您的導航欄添加到入門模板中，然后更改：

<nav class="navbar navbar-inverse">

進入

<nav class="navbar navbar-inverse navbar-fixed-top">

我認為您忘記了代碼中的javascript：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://getbootstrap.com/dist/js/bootstrap.min.js"></script>

在getbootstrap.com上

需要JavaScript插件如果禁用了JavaScript並且視口足夠窄以至於導航欄折疊，則將無法展開導航欄並查看.navbar-collapse中的內容。

響應式導航欄要求將崩潰插件包含在您的Bootstrap版本中。

我已經解決了這個問題。 在我的CSS中，有一點：

.navbar-collapse.collapse {
    text-align: center
    display: block !important;
    height: auto !important;
    padding-bottom: 0;
    overflow: visible !important;
}

我刪除了所有規則，但text-align和navbar正常工作。

謝謝大家的協助。
