Blogger Blogspot 来自桌面的移动设备的不同 header1 图像

Question

希望在我的移动模板主题与 blogger/blogspot 博客上的桌面主题上显示不同的背景图像。

目前它在 Layout/Header1 小部件中显示为桌面主题上传的相同图像。

下面的代码 sn-p 显示了 Header1 小部件。我想 A：用一张图片来代替博客的标题和描述； B：为移动设备和桌面设备使用不同的图像。

我正在查看 !--Show Image Only 区域，不确定如何添加 if:data:blog.isMobile

      Show image as background to text. You can't really calculate the width
      reliably in JS because margins are not taken into account by any of
      clientWidth, offsetWidth or scrollWidth, so we don't force a minimum
      width if the user is using shrink to fit.
      This results in a margin-width's worth of pixels being cropped. If the
      user is not using shrink to fit then we expand the header.

Answer 1

使用data:blog.isMobileRequest 而不是data:mobile

<b:if cond='data:blog.isMobileRequest'>
  <div style='background-image: url(
