bootstrap table,如何平均对齐每个<td>?

bootstrap-4 html

LearnProgramming · 技术社区 · 6 年前

正如你在下面的图片中看到的,红线代表了每一条的宽度不等。 <td> . 我的目标是制造每一个 <TD & GT; 均匀对齐。我该怎么做?

CSS

.stickyFooter {
            background: #c1c1c1;
            position: fixed;
            left: 0;
            right: 0;
            bottom: 0;
            height: 50px;
            font-size: 13px;
        }

代码

<div class="stickyFooter wrap visible-sm visible-xs table-responsive" style="margin-bottom: 0px; border: none;">
<table class="table">
    <tr align="center">
        <td><a href="#"><i class="fa fa-home fa-2x"></i><br>Home</a></td>
        <td><a href="#"><i class="fa fa-bell fa-2x"></i><br>Notification</a></td>
        <td><a href="#"><i class="fa fa-file-invoice-dollar fa-2x"></i><br>Transaction</a></td>
        <td><a href="#"><i class="fa fa-search fa-2x"></i><br>Directory</a></td>
        <td><a href="#"><i class="fa fa-newspaper fa-2x"></i><br>Ads</a></td>
        <td><a href="#"><i class="fa fa-dollar-sign fa-2x"></i><br>Billing</a></td>
        <td><a href="#"><i class="fa fa-plus fa-2x"></i><br>More</a></td>
        <td><a href="#"><i class="fa fa-cogs fa-2x"></i><br>Setting</a></td>
    </tr>
</table>

额外的宽度很可能来自您在那里的fontAwesome图标,默认情况下,这些图标具有不同的宽度。这可以通过应用类来纠正 fa-fw 到每个图标:

td {
  border: 1px solid black;
  min-width: 200px;
}

      <td><a href="#"><i class="fa fa-fw fa-home fa-2x"></i><br>Home</a></td>
      <td><a href="#"><i class="fa fa-fw fa-bell fa-2x"></i><br>Notification</a></td>
      <td><a href="#"><i class="fa fa-fw fa-file-invoice-dollar fa-2x"></i><br>Transaction</a></td>
      <td><a href="#"><i class="fa fa-fw fa-search fa-2x"></i><br>Directory</a></td>

      <td><a href="#"><i class="fa fa-fw fa-dollar-sign fa-2x"></i><br>Billing</a></td>
      <td><a href="#"><i class="fa fa-fw fa-plus fa-2x"></i><br>More</a></td>
      <td><a href="#"><i class="fa fa-fw fa-cogs fa-2x"></i><br>Setting</a></td>
    </tr>
  </table>
</div>

记住 <td> 单元格将自动展开以填充其可用宽度 <tr> 容器和文本较长的单元格将“希望”在这方面占用更多空间。如果要强制约束(或展开)它们,只需为它们定义 width .

这也可以在上面的示例中看到,其中我声明必须至少是 200px 每个都很宽。
