Now spaces are not more of fixed width. Because a margin of 3em must be the same in portrait or landscape mode (the same should happen with a negative indent of -3em).

I took a look at the book and the problem has to do with how margin and indent are handled during conversion to KFX format. Your CSS:

.hanging {
   text-indent: -3em;
   margin-left: 3em;
}

translates in KFX into:

  text_indent: {
    value: -9.375,
    unit: percent,
  },
  margin_left: {
    value: 9.375,
    unit: percent,
  },

So the indentation is being rendered as a fixed percentage of the screen size in KFX.
