Does Firefox support break-after: avoid?
I'm creating a print stylesheet, and trying to use break-after: avoid to keep headings on the same page as the following paragraph, but it doesn't seem to work.
To investigate, I created a simple page with anin between a number of paragraphs to that the <h2> printed as the last item on the page. I then added the following styles. @media print { h2 { break-after: avoid; } } I expected the heading to move to the next page, but nothing happened. So then I added the following: CSS: @supports (break-after: avoid) { .message { display: block; } } HTML:
break-after: avoid is supported.
When I refreshed the page, the message appeared. So is break-after supported or not, or is it not supported for paged media? Or if it is supported, what am I doing wrong? MDN suggests it's been supported since Firefox 65, but maybe I'm misunderstanding the compatibility table.
Thanks in anticipation. If this is the wrong forum to ask this question, perhaps somebody could direct me to the correct one.

Sorry, it looks like my question has made the display go mad, I hope you can make sense of it.

This forum is for end user support, so not really the right place to ask :-) but https://bugzilla.mozilla.org/show_bug.cgi?id=775617 being unresolved suggests this isn't expected to work.
On my own sites I user the older method of putting the heading and first paragraph following in a div styled with:
page-break-inside: avoid;
Not the best design, but possibly useful in some cases.
Thank you, that's a shame. It's curious that @supports suggests it should work, and MDN is ambiguous too. Maybe that bug report will get fixed one day, we can but hope.
To jscher2000: thanks for the suggestion, I might try that.
