如何使用引导网格格式化HTML电子邮件？

Question

这个示例（实际的电子邮件内容）：

<section><div class="m_-5028752718443096113row">
        <div class="m_-5028752718443096113col-sm-6">
        <section><p>The quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the river</p>
</section></div>
        <div class="m_-5028752718443096113col-sm-6">
        <section><p>The quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the riverThe quick brown fox jumps over the lazy dog near the bank of the river</p>
</section></div>
    </div></section>

col类已更改，并添加了前缀。 （这是我第一次发送带有bootstrap类的电子邮件）

如果我在电子邮件中包含bootstrap cdn类，它仍然可以识别它的类，即使它们被更改了吗？
