html - 需要删除 Div 之间的垂直间距

Question

我是 Web Dev 的新手，我正面临一个关于 Div 的问题:https://jsfiddle.net/debashis_gt540m/17mmmxps/2/最后的三个 div 在它们之间有一定的间距，我尝试将所有 3 个 div 插入一个，但没有帮助。任何人 ？我想去掉 3 个 div 之间的空格。代码是:

<nav class="navbar navbar-inverse navbar-fixed-top">
  <div class="container-fluid">
    <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="https://in.linkedin.com/in/debdebashis"   target="_blank">Debashis Deb</a>
