XYZ brand ereader IS NOT the standard we design to.
EPUB designs are for 1 up devices, not 2 or 3 up. Not multi column.
ONE UP

Or if you also put a (non printing) line in, then Pagebreak: always; if you want on right.
BUT
Not every viewer even honors all CSS commands (xyz developers
know better what you want.
