[Heya! For future reference, please send plain-text emails to this
list <https://wiki.csswg.org/tools/www-style>.  Your color usage in
your example code makes them incredibly hard to read.]

I'm sorry, but I don't understand the relevance of your example code

vertical/horizontal tag, while Appendix B is example code for the
day/night style tags.  Your example code for each appears to be doing
something completely different.
