我创建了一个电子邮件模板，经测试可以在桌面客户端（如gmail / yahoo / outlook）上正常运行，并且还在移动gmail应用上测试了正确的响应行为。我使用的是Android / Galaxy S4。
响应式样式在雅虎移动应用上无效。事实上，它并没有从'style'中读取CSS规则。虽然桌面镶嵌设置为移动视图（使用Inspect - ＆gt;切换设备工具栏）并登录到yahoo邮件，但会显示阅读响应式样式的电子邮件。
问题：雅虎移动应用程序不支持响应能力吗？或者，它是否特别需要额外的黑客攻击？
更新： 我尝试将CSS样式从头部移动到正文。然后它读取样式。但是，在身体中使用样式可能不是一个好主意，gmail移动应用程序现在忽略它。
以下是我使用的电子邮件代码：
