I appreciate the feed back.
in addition to not implementing the alternate stylesheets iaw the ipdf spec, iBooks night mode also disregards
Code:
background: <color>
and
statements.
I've got an email into the iBookstore team, who's referred my questions about night mode to the technical folks. Here's to hoping they have a workaround, or tell me I was just doing it wrong along with an example of how to do it correctly.
