你可以使用下面的CSS:

.text-right {text-align: right} /* For right align */
.text-left {text-align: left} /* For left align */
.text-center {text-align: center} /* For center align */

 <p class="text-left">Left</p>
 <p class="text-center">Center</p>

Bootstrap 2.3具有文本左、文本右和文本中心实用程序类，但它们不能在表格单元格中工作。直到Bootstrap 3.0发布(他们已经修复了这个问题)，我能够进行切换，我已经将此添加到我的网站CSS中，在Bootstrap . CSS之后加载:

.text-right {
    text-align: right !important;
}

.text-center {
    text-align: center !important;
}

.text-left {
    text-align: left !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>
