我在网站上有两个不同的页面/节点，我想在CSS中为背景图像设置不同的@page规则。我特别不熟悉打印规则（尽管我每天使用CSS工作），因此我不确定如何完成此操作
我试图将@page与2018-03-28 10:37:51,530 URL used: https://my.domain.org/is/api/getData/D_01

这样的内容放在一起，但这并没有做任何事情。这甚至是可能的，还是@page不可能与类或id配对 - 在这种情况下，我该如何解决这个问题？
编辑，尝试过以下但是没有工作：
body.node-type @page{}我知道我可能会将背景图片放在一个单独的div中，但这需要对代码进行重大修改，而且我甚至不确定在溢出时它是否会很好用到第二页（因为第一页在两个节点类型中都是唯一的。）
答案 0 :(得分：0)
您无法单独在@page at-rule内执行此操作。 CSS不支持条件@page at-rules，条件依赖于匹配标记内的选择器。
正如您所发现的那样，通过将@page at-rule包含在您希望规则应用的页面中嵌入的<style>中，可以解决这个问题（假设您有这样的课程）重新匹配在body元素上，这通常表示文档特定的样式。
