Outlook.com邮件背景图片无法显示的技术咨询

问题根源分析 #

你的代码存在两处关键语法错误，导致Outlook.com无法正确解析背景图：

1. VML标签闭合错误：<v:fill>是自闭合标签，但后续额外添加了</v:fill>闭合标签，破坏了VML结构。
2. 中文引号错误：<v:fill>里的color="#ffffff”使用了中文双引号，而非英文双引号，导致属性解析失败。

额外优化建议 #

• 移除<td>上重复的valign="top"属性，避免代码冗余。
• Outlook.com对background-size:cover支持有限，若需完美适配，可使用固定尺寸的背景图，或调整VML的尺寸定义匹配图片比例。
