html - 在表跨表行中添加图像以相对于其他非跨行保持居中

Question

尝试使用下面的电子邮件签名，但我无法让跨行中的图像在所有电子邮件客户端中保持居中 - 它在 JSBin 中工作正常，但在 GMail 中加载时显示不均匀。我需要更改什么才能使其在 GMail 中正确显示(居中)？

Answer 1

图片必须有 display: block 属性才能有 100% 的高度
尝试将图像中的 display: inline-block; 替换为 display: block;
看看这个例子

#TemplateLogo{
  display: block;
  margin-left: auto;
  margin-right: auto;
  vertical-align: baseline;
}

#TemplateLogo2{
  display: inline-block;
  margin-left: auto;
  margin-right: auto;
  vertical-align: baseline;
}

tbody{
  display:block;
  border: 1px solid red;
}

h3{
  font-family: Arial;
}
