html - 使用 bootstrap 导航栏并希望使用 css 将链接居中

Question

我正在使用 Bootstrap 导航栏，我在导航栏中有我的链接。链接默认在左侧。我能够将链接移动到页面中心的唯一方法是让 css 给第一个列表项留出 20em 的边距。我想让它针对不同尺寸的显示器进行调整，但是如果显示器更大，它仍然会居中。这是 Bootstrap 导航代码的一部分，其中包含我的链接和下面的 CSS:

<nav class="navbar navbar-default">
    <!--<div class="container">-->
      <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="#">Chompsta</a>
      </div>
      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav">
          <li class="margin-left"><a href="#">Chat anonymously</a></li>
          <li><a href="#">Register for fame</a></li>
          <li><a href="#">Search for topics</a></li>
        </ul>
        <ul class="nav navbar-nav navbar-right">
          <li><div id="points">172</div></li>
        </ul>
      </div><!-- /.navbar-collapse -->
    <!--</div>&lt;!&ndash; /.container-fluid &ndash;&gt;-->
  </nav>

css

.margin-left { margin-left: 20em; }

这可能会解决您的问题或让您朝着正确的方向前进。这将使您的主要 navbar 链接居中，并使您的 navbar-right 保持在其位置。

@media (min-width: 768px) {
  .navbar .navbar-nav {
    display: inline-block;
    float: none;
    vertical-align: top;
  }
  .navbar .navbar-collapse {
    text-align: center;
  }
}

      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>

    </button> <a class="navbar-brand" href="#">Chompsta</a>
