降低bootstrap 3.0导航栏的高度
降低bootstrap 3.0导航栏的高度
提问于 2013-09-04 03:14:28
我正在尝试减少bootstrap 3.0导航栏高度，它用于固定顶部行为。这里我使用的是代码。
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, 0, 0, .25), inset 0 -1px 0 rgba(0, 0, 0, .1);-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .25), inset 0 -1px 0 rgba(0, 0, 0, .1);box-shadow: 0 1px 3px rgba(0, 0, 0, .25), inset 0 -1px 0 rgba(0, 0, 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, 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
从屏幕上看，导航栏的输出减少了，但高度没有减少。原始高度以粉红色显示。
上面的css脚本在bootstrap 2中几乎工作得很好。*
有没有办法适当地降低高度。

在花了几个小时之后，添加了以下css类解决了我的问题。
与Bootstrap 3.0配合使用。*
.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，以自定义和减少屏幕截图导航栏的高度。
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; }使用代码：
<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>

工作解决方案：
Bootstrap 3.0默认在顶部和底部都有15px的填充，所以我们只需要覆盖它！
例如：
.navbar-nav > li > a {padding-top:10px !important; padding-bottom:10px !important;}
.navbar {min-height:40px !important}Stack Overflow用户

只需覆盖.navbar中设置的最小高度，如下所示：
.navbar{
min-height:20px; //* or whatever height you require
}将元素高度更改为小于最小高度的值不会有什么不同。
