Question

在小屏幕上的以下html导致列重叠：

    <form method="get">
      <div class="row form-group">
        <div class="col-8">
          <input name="custName" value="" class="form-control" placeholder="Customer" />
        </div>
        <div class="col-4">

          <button type="button" class="btn btn-secondary">Clear</button>
        </div>
      </div>
    </form>
  </div>
  <div class="col-sm-3">
    <nav aria-label="Pagination">
      <ul class="pagination float-right">
        <li><a class="page-link" href="#">Prev</a></li>
        <li><a class="page-link" href="#">1</a></li>
        <li><a class="page-link" href="#">2</a></li>
        <li><a class="page-link" href="#">3</a></li>
        <li><a class="page-link" href="#">Next</a></li>
      </ul>
    </nav>
  </div>
</div>

我需要右对齐导航元素。如何防止列重叠？

Answer 1

这不是错误。它正在作为设计。只能有一定数量的空间，显然您不能将所有内容都放在那儿，并期望它们看起来仍然不错并且排成一排。

您可以将断点从sm更改为lg，以便这些列更早地成为行？
