css 是否可以在分页后重复内容？您能检测到分页吗？

我有一个很大的网页，在打印时经常需要多个分页符。然而，这意味着内容是从父布局结构的其余部分分割出来的，用户可能不明白它涉及到哪个问题。类似下面的例子

当前行为

A 1 i   What is the capital of Peru?
    ii  What is the capital of Brazil?
    iii What is the capital of Equador?
  2 i   What is the population of France?
    ii  What is the population of Spain?
___________________________________________
    iii What is the population of Italy?

我想做的是在页面的开头重复问题的编号，这样孤立的问题就有了父母的参考。

理想行为

A 1 i   What is the capital of Peru?
    ii  What is the capital of Brazil?
    iii What is the capital of Equador?
  2 i   What is the population of France?
    ii  What is the population of Spain?
___________________________________________
A 2 iii What is the population of Italy?

有没有办法用CSS做到这一点？我不知道如何使用CSS的'分页'属性将工作。否则也许Javascript？我将使用wkhtmltopdf转换html到pdf的方式。
添加了一些示例代码。

下面的代码使用响应网格系统和CSS page-break-inside属性。
基本上，我们将page-break-inside属性的值设置为avoid，这意味着在同一页上显示整个项目，并且在分页符处不对其进行分隔，这意味着整个项目将显示在同一页上。
在您的例子中，我们将整个主组封装到一个div中，并分配page-break-inside属性。为了得到一个表格结构，我们将使用CSS网格系统、行和列。
现在，这段代码没有复制主q.no，在一个分页上的子q.no，但是它把同一个主q.no的所有问题都放在同一页上。
这段代码也可以通过for循环来实现，以便动态填充页面。
注意print CSS类。它被分配到我们正在创建一个新的主问题的行。如果这符合你的目的，我可以帮助你设计for循环，如果它看起来很复杂...

通过在CSS中使用page-break-after: avoid;，你可以告诉网站在打印指定对象时尽可能避免断页。或者，你可以用page-break-after或page-break-before设置类，这样打印机就知道什么时候应该把东西推下来或保持在上面。我希望这能有所帮助，这里是我用来参考的文档。
