I think auto-pagination is the way forward. Here's a demo of Opera
running in paged mode on a tablet:


  (the demo starts around 6:30 into the interview)

By having the browser automatically split pages, we can support a wide
range of devices with little work on the authoring side. We can still
support special formatting for the first page, second page,
every-third-page etc. to give a rich visual experience, but I don't
believe having page breaks in fixed places is what designers care most

If you want fixed lines and pages, PDF is a better format than HTML/CSS.

Yes, this is what 'float-defer-page' was created for. You can e.g. say:

  div.ad { float-defer-page: 2 } 


to make it the ad appear on the its natural page + 2.

I don't think there is anything wrong in having images/figures inside articles, like:


If you want the figures to start ona a new page, you could say:

   figure { break-before: page }

Or, if you want to avoid page breaks (which often cause empty white
page on the preceding page), you can float the figure to the top of
the page:

   figure {
     float: top;
     clear: page;

The above code also clears the page, to ensure that there is no other content above it:


Finally, if you want the figure to be alone on a page, you can say:

  figure {
    float: top;
    margin-bottom: auto;
