Question

我正在构建一个应该贴在页面顶部的navbar。我用.navbar-fixed-top类来完成它并给了body元素，填充70px。现在处于折叠模式（移动分辨率），当切换时，它提供垂直导航。

不确定此滚动的来源。

以下是代码：

<header class=" container-fluid navbar-fixed-top">

  <!-- header navbar -->
  <nav class="navbar navbar-default">
    <div class="container">
      <!-- Brand and toggle get grouped for better mobile display -->
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="market.html"><img src="images/logo-inner.jpg" / alt="B-Hive: Expand your business"></a>
      </div>

      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

        <!-- Form search start -->
        <form class="navbar-form navbar-left" role="search" class="top-search-padding">
          <div class="form-group">

            <div class="search-div ui-widget">
              <input id="tags" type="text" class="txt-search" placeholder="Search people, products and services">

              <button type="submit" class="btn-search"><img src="images/search-icon.png" /></button>
            </div>
          </div>
        </form>
        <!-- Form search end -->
        <ul class="nav navbar-nav navbar-right">
          <li class="top-menu-links-active"><a href="#">MARKET</a></li>
          <li><a class="top-menu-links" href="#">EXHIBITIONS</a></li>

            <ul class="dropdown-menu">
              <li><a href="#">Account</a></li>
              <li><a href="#">Privacy</a></li>

              <li role="separator" class="divider"></li>

                </ul>
              </li>

            </ul>
          </li>



        </ul>
      </div>
      <!-- /.navbar-collapse -->
    </div>
    <!-- /.container-fluid -->
  </nav>
  <!-- /header navbar -->

</header>

不要在顶部使用标题，只需从导航

开始

            <nav class="navbar navbar-default">
           <div class="container-fluid">
           <!-- Brand and toggle get grouped for better mobile display -->
          <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-     
          toggle="collapse" data-target="#bs-example-navbar-collapse-1"   
         aria-expanded="false">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>
  <a class="navbar-brand" href="#">Brand</a>
</div>

<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
  <ul class="nav navbar-nav">
    <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown"    
     role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span  
      class="caret"></span></a>
      <ul class="dropdown-menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li role="separator" class="divider"></li>
        <li><a href="#">Separated link</a></li>
        <li role="separator" class="divider"></li>
        <li><a href="#">One more separated link</a></li>
      </ul>
    </li>
  </ul>
  <form class="navbar-form navbar-left" role="search">
    <div class="form-group">
      <input type="text" class="form-control" placeholder="Search">
    </div>
    <button type="submit" class="btn btn-default">Submit</button>
  </form>
  <ul class="nav navbar-nav navbar-right">
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown"   
     role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span 
       class="caret"></span></a>
      <ul class="dropdown-menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li role="separator" class="divider"></li>
        <li><a href="#">Separated link</a></li>
      </ul>
           </li>
          </ul>
        </div><!-- /.navbar-collapse -->
          </div><!-- /.container-fluid -->
          </nav>

Answer 2

试试这个。

OFFSET1=`date +%y%m%d -d "2 day ago"`

还提到这个文件： Bootstrap.min.css，bootstrap.min.js＆amp; jquery.min.js

Answer 3

Bootstrap的.navbar-collapse有一个默认max-height: 340px;，当导航内的链接超过此高度时会导致滚动条出现。

您只需删除此属性即可避免滚动条显示在移动视图中。
