and

. I did not do further tests

Describe alternatives you've considered
For a good control over page breaks with css, I see no alternatives. Remaining single lines or just breaking one word to the next page needs to be avoided for well designed documents.

Hi Bernd

I understand the problem with orphans and widows, thank you.
As a work around the css break-inside: avoid; works, set on a parent, so the layout is kept together.
I know this is sometimes not possible with very long passages, and causes me visual pain too.

I will add it to the list.
