Question

我正在使用一个bootstrap 3网站，我想在边框的帮助下使导航栏中的链接变得更低，如下所示：

但目前它看起来像这样：

我试过＆＃34; padding-bottom＆＃34;属性，但没有任何作用。
我的HTML：

    <nav class="navbar navbar-default navbar-fixed-top">
  <div class="container">
    <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>
      <a class="navbar-brand navbar-left" href="/index.html"><img class="nav-logo" src="/images/xcellent-logo/logo.png"></a>
    </div>
    <div id="navbar" class="navbar-collapse collapse">
      <ul class="nav navbar-nav nav-underline">
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Services<span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="stuff">stuff</a></li>
            <li><a  href="stuff">stuff</a></li>
            <li><a href="stuff">stuff</a></li>
            <li><a  href="stuff">stuff</a></li>
            <li><a  href="stuff">stuff</a></li>
          </ul>
        </li>
        <li><a  href="stuff">stuff</a></span></li>
        <li><a  href="stuff">stuff</a></span></li>
        <li><a  href="stuff">stuff</a></span></li>             
      </ul>
    </div><!--/.nav-collapse -->
  </div>
</nav>

我试过的CSS：

.nav-underline a {
border-bottom: transparent solid 2px;
padding-bottom: 40px;
}
.nav-underline a:hover {
border-bottom: $white solid 2px;
}

有没有办法实现这个目标？谢谢你的帮助！

只需将锚点填充移至li即可。这是自定义css 相同。

.navbar-nav.nav-underline>li>a {
  padding: 0px;
}

.navbar-nav.nav-underline>li {
  padding: 15px;
}

以下是工作示例：

.nav-underline a {
  border-bottom: transparent solid 2px;
  padding-bottom: 40px;
}

.nav-underline a:hover {
  border-bottom: red solid 2px;
}

.navbar-nav.nav-underline>li>a {
  padding: 0px;
}

.navbar-nav.nav-underline>li {
  padding: 15px;
}
