扩展David的回答，我只是添加了一个简单的类来增强Bootstrap，像这样:

.money, .number {
    text-align: right !important;
}

Bootstrap 4有五个类:text left, text center, text right, text justify和text nowrap。

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/> <div class="text-left">Left aligned text.</div> <div class="text-center">Center aligned text.</div> <div class="text-right">Right aligned text.</div> <div class="text-justify">Justified text starts here. The quick brown fox jumps over the lazy dog. Justified text ends here.</div> <div class="text-nowrap">No wrap text starts here. The quick brown fox jumps over the lazy dog. No wrap text ends here.</div>

在Bootstrap版本4。有一些内置的类来定位文本。

对表头和数据文本进行居中:

 <table>
    <tr>
      <th class="text-center">Text align center.</th>
    </tr>
    <tr>
      <td class="text-center">Text align center.</td>
    </tr>
  </table>

您还可以使用这个类来定位任何文本。

<p class="text-left">Left aligned text on all viewport sizes.</p>
<p class="text-center">Center aligned text on all viewport sizes.</p>
<p class="text-right">Right aligned text on all viewport sizes.</p>

<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
<p class="text-md-left">Left aligned text on viewports sized MD (medium) or wider.</p>
<p class="text-lg-left">Left aligned text on viewports sized LG (large) or wider.</p>
<p class="text-xl-left">Left aligned text on viewports sized XL (extra-large) or wider</p>

欲知详情

现在，随着Bootstrap 3的发布，你可以使用text-center类进行中心对齐，text-left类进行左对齐，text-right类进行右对齐，text-justify类进行对齐。

Bootstrap是一个非常简单的前端框架，一旦你使用它。以及非常容易定制，以满足您的喜好。
