如何在导航栏的内容中从左到右提供空间

问题描述

我想开发一个navbar，其内容左右左右都有空间，它也应该支持移动屏幕和台式机屏幕，但是我无法获得它。

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">eNno</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Service</a>
      </li>

      <li class="nav-item">
        <a class="nav-link" href="#">Blog</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Portifolio</a>
      </li>

      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
  </div>
</nav>

这是我的代码的输出

我怎么得到

解决方法

您可以在<nav>内插入Bootstrap .container。这将在左侧和右侧设置适当的边距。另外，将navbar-nav mr-auto更改为navbar-nav ml-auto，以使导航栏项目向右对齐。

    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav ml-auto">
        <li class="nav-item active">
          <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Service</a>
        </li>

        <li class="nav-item">
          <a class="nav-link" href="#">Blog</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Portifolio</a>
        </li>

        <li class="nav-item">
          <a class="nav-link" href="#">Contact</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

结果如下：
