你如何降低Bootstrap 4中的导航栏高度？

Question

下面是我的bootstrap 4代码

 <nav class="navbar navbar-collapse navbar-toggleable-md navbar-light bg-faded ">
    <div class="collapse navbar-collapse" id="navbarText">
      <ul class="navbar-nav mr-auto">

        <li class="nav-item">

          <a class="nav-link " >
            <span  class="icon icon18 icon-upload"></span>
            Input Data From Prior Month
            </a>
        </li>
        <li class="nav-item">
          <a class="nav-link " >
            <span  class="icon icon18 icon-excel-file"></span>
            Export to Excel
          </a>
        </li>
      </ul>
      <span class="navbar-text color-blue">
        *Data Automatically pulled from sources
      </span>
    </div>
   </nav>

这里为bootstrap 3提供了各种示例 如何降低Bootstrap 3中的导航栏高度？ 但是它们似乎都没有用于bootstrap 4,任何人都可以帮助这个吗？

使用spacing utils在Bootstrap 4中减小Navbar高度更容易.导航栏的高度来自Navbar内容中的填充.

只要使用py-0在nav-link与navbar-text..

<nav class="navbar navbar-collapse navbar-toggleable-md navbar-light bg-faded ">
    <div class="collapse navbar-collapse" id="navbarText">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item">
                <a class="nav-link py-0">
                    <span class="icon icon18 icon-upload"></span> Input Data From Prior Month
                </a>
            </li>
            <li class="nav-item">
                <a class="nav-link py-0">
                    <span class="icon icon18 icon-excel-file"></span> Export to Excel
                </a>
            </li>
        </ul>
        <span class="navbar-text py-0 color-blue">
        *Data Automatically pulled from sources
      </span>
    </div>
</nav>

将py-0类设置padding-top:0;padding-bottom:0的项目.
