Yes, iBooks Author can do some of that in ePub 3 but at what cost?

  1. It will only work in iBooks.
  2. They must tell iBooks it is a fucking snowflake (RMT format)
  3. This snowflake can’t reflow, be displayed in night mode, etc.

This is absolutely pathetic since if you think about it for a minute, it’s just the worst of both worlds (reflow and fixed-layout).

[edit] and oh yeah, let me introduce the prefixed property “-ibooks-layout-hint”, which Apple is using for this snowflake. For instance,

a.pageShape { 
  -ibooks-layout-hint: anchor page shape;
  display: none;
}
a.anchor { 
  -ibooks-layout-hint: anchor;
  display: none;
}
a.attachment { 
  -ibooks-layout-hint: inline;
  display: none;
}
a.shape { 
  -ibooks-layout-hint: shape;
  display: none;
}

I don’t even know what they are used for since they are undocumented but they were already used in the .iBooks format.
