【中文标题】为啥我的电子邮件 HTML 顶部的左边距和右边距没有变化？【英文标题】：Why left and right margins don't change in the top of my e-mail's HTML?为什么我的电子邮件 HTML 顶部的左边距和右边距没有变化？ 【发布时间】：2016-10-04 18:45:33 【问题描述】：我正在努力更改电子邮件 html 顶部文本的边距。我需要我的文本在左侧占据更多空间，这样它就不会挤在右上角，也不会跑 4 行。代码如下：

</html>【问题讨论】：
对于 HTML 邮件，仅使用内联样式，因为大多数邮件客户端会删除标题中的所有内容，包括 css 样式链接。 【参考方案1】：table 中的width 总是很棘手。 td 的宽度不仅取决于应用到它的宽度，还取决于 body 和其他 tds 的宽度，它们是它们的兄弟。因此，您必须调整其他 tds 和内部 table 宽度，以便为文本提供更多空间。

如果您不需要特殊布局，您可以删除所有widths。所有td 都会根据其容器自动调整。
我粗略地改变了另一个宽度和tds 和tables。如果您正在创建电子邮件模板，最好内联所有样式。大多数电子邮件客户端都会忽略标题中的样式。
