twitter-bootstrap – 降低bootstrap 3.0 navbar的高度

我试图减少bootstrap 3.0 navbar高度，用于固定顶行为。这里我使用代码。

HTML

<div class="tnav">
<div class="navbar navbar-fixed-top" role="banner">
    <div class="navbar-inner-sm">
  <div class="container">
    <div class="navbar-header">
      <button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".bs-navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
    </div>
    <nav class="collapse navbar-collapse" role="navigation">
      <ul class="nav navbar-nav pull-right">
        <li class="active">
          <a href="../getting-started">Getting started</a>
        </li>
        <li>
          <a href="../css">Ext01</a>
        </li>
        <li>
          <a href="../components">Language</a>
        </li>
        <li>
          <a href="../javascript">My Account</a>
        </li>
        <li>
          <a href="../customize">Sign Out</a>
        </li>
      </ul>
    </nav>
  </div>
    </div>
</div>

CSS

.tnav .navbar { background:#F06; height:30px; }
.navbar-inner-sm{background-color: #282828;padding: 1px 20px;background-repeat: repeat-x;-webkit-Box-shadow: 0 1px 3px rgba(0,.25),inset 0 -1px 0 rgba(0,.1);-moz-Box-shadow: 0 1px 3px rgba(0,.1);Box-shadow: 0 1px 3px rgba(0,.1);background-image: linear-gradient(top,#333333,#222222);}
.navbar-inner-sm .nav {position: relative;left: 0;display: block;float: left;margin: 0 10px 0 0;}
.navbar-inner-sm .nav.pull-right {float: right;}
.navbar-inner-sm .nav > li {display: block;float: left;}
.navbar-inner-sm .nav > li > a {float: none;padding: 4px 5px;line-height: 19px;color: #999999;text-decoration: none;text-shadow: 0 -1px 0 rgba(0,0.25);}
.navbar-inner-sm .nav > li > a:hover {background-color: transparent;color: #ffffff;text-decoration: none;}
.navbar-inner-sm .nav .active > a,.navbar .nav .active > a:hover {color: #ffffff;text-decoration: none;background-color: #003753;}
.navbar-inner-sm .divider-vertical {height: 27px;width: 1px;margin: 0 9px;overflow: hidden;background-color: #282828;border-left: 1px solid #3f3f3f; border-right: 1px solid #161616;}
.navbar-inner-sm .nav.pull-right {margin-left: 10px;margin-right: 0;}

结果

从屏幕上显示，导航栏输出减少，但高度不降低。原始高度显示为粉红色。

以上css脚本几乎工作良好在bootstrap 2. *

有什么办法正确减少高度。

解决方法

花了几个小时后，添加以下CSS类固定了我的问题。

使用Bootstrap 3.0。*

.tnav .navbar .container { height: 28px; }

使用Bootstrap 3.3.4

.navbar-nav > li > a,.navbar-brand {
    padding-top:4px !important; 
    padding-bottom:0 !important;
    height: 28px;
}
.navbar {min-height:28px !important;}

更新
完整的代码来自定义和减少导航栏的高度与屏幕截图。

CSS：

/* navbar */
.navbar-primary .navbar { background:#9f58b5; border-bottom:none; }
.navbar-primary .navbar .nav > li > a {color: #501762;}
.navbar-primary .navbar .nav > li > a:hover {color: #fff; background-color: #8e49a3;}
.navbar-primary .navbar .nav .active > a,.navbar .nav .active > a:hover {color: #fff; background-color: #501762;}
.navbar-primary .navbar .nav li > a .caret,.tnav .navbar .nav li > a:hover .caret {border-top-color: #fff;border-bottom-color: #fff;}
.navbar-primary .navbar .nav > li.dropdown.open.active > a:hover {}
.navbar-primary .navbar .nav > li.dropdown.open > a {color: #fff;background-color: #9f58b5;border-color: #fff;}
.navbar-primary .navbar .nav > li.dropdown.open.active > a:hover .caret,.tnav .navbar .nav > li.dropdown.open > a .caret {border-top-color: #fff;}
.navbar-primary .navbar .navbar-brand {color:#fff;}
.navbar-primary .navbar .nav.pull-right {margin-left: 10px; margin-right: 0;}
.navbar-xs .navbar-primary .navbar { min-height:28px; height: 28px; }
.navbar-xs .navbar-primary .navbar .navbar-brand{ padding: 0px 12px;font-size: 16px;line-height: 28px; }
.navbar-xs .navbar-primary .navbar .navbar-nav > li > a {  padding-top: 0px; padding-bottom: 0px; line-height: 28px; }
.navbar-sm .navbar-primary .navbar { min-height:40px; height: 40px; }
.navbar-sm .navbar-primary .navbar .navbar-brand{ padding: 0px 12px;font-size: 16px;line-height: 40px; }
.navbar-sm .navbar-primary .navbar .navbar-nav > li > a {  padding-top: 0px; padding-bottom: 0px; line-height: 40px; }

用法代码：

<div class="navbar-xs">
   <div class="navbar-primary">
       <nav class="navbar navbar-static-top" role="navigation">
          <!-- Brand and toggle get grouped for better mobile display -->
          <div class="navbar-header">
              <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-8">
                 <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-8">
              <ul class="nav navbar-nav">
                  <li class="active"><a href="#">Home</a></li>
                  <li><a href="#">Link</a></li>
                   <li><a href="#">Link</a></li>
              </ul>
          </div><!-- /.navbar-collapse -->
      </nav>
  </div>
</div>
