您好，我已经尝试更改 CSS 文件中的 bootstrap class' 功能，但我尝试的任何操作都没有给我想要的结果（即图片右侧以下）。我不确定我应该修改哪个 class。有人可以帮我吗？

注：我上面提供的图片对比是在按下折叠按钮后从移动角度看的。

如果您在表格中使用 Bootstrap class justify-content-center，它将按照您在右图中的要求进行操作。链接将出现在导航栏背景上。

<form class="form-inline my-2 my-lg-0 justify-content-center">
      <a class="nav-link" href="#">Link</a>
      <a class="nav-link" href="#">Link</a>
      <a class="nav-link" href="#">Link</a>
</form>

如果您希望链接与导航栏内联，请添加 classes mt-n5 和 pt-2.

<form class="form-inline my-2 my-lg-0 justify-content-center mt-n5 pt-2">
      <a class="nav-link" href="#">Link</a>
      <a class="nav-link" href="#">Link</a>
      <a class="nav-link" href="#">Link</a>
</form>
