HTML 电子邮件 - header 图片未在 Thunderbird 中居中
HTML Email - header image not centered in Thunderbird
我使用 HTML 电子邮件模板来创建我的 HTML 电子邮件，它在任何地方看起来都不错，除了 thunderbird。正如您在屏幕截图中看到的那样，header 图像并未在其余内容上方居中。有没有办法对此进行调试，或者有人知道这里的问题是什么吗？

感谢您使用 Cerberus！我在重现您的问题时遇到问题，但在 Hero Image 部分添加了一些内容以防弹：
<!-- Hero Image, Flush : BEGIN -->
<tr>
<td background-color="#ff0000" align="center"> <!-- Center align the table cell -->
<img src="http://via.placeholder.com/600x300" width="600" height="" alt="Coinlend header" border="0" align="center" style="width: 100%; max-width: 600px; height: auto; background: #dddddd; font-family: sans-serif; font-size: 15px; line-height: 20px; color: #555555; margin: auto;" class="g-img"> <!-- margin: auto; in case the image has trouble centering itself -->
</td>
</tr>
<!-- Hero Image, Flush : END -->
我还将您的 <td> bgcolor 从 #0c151d 更改为亮红色。我经常使用这种技术来准确指出标签未对齐。
如果这对您有帮助，请告诉我。我负责维护 Cerberus，很乐意帮助您解决这个问题。
