Reply To: Epubs optimized for specific devices

iBooks need a special code in the heading section. Other epub sites do not. I am not sure if they differ. Of course, Kindle needs the epubs converted to mobi. Also fixed-layout requires Comic Book Creator. Textbook Creator only accepts pdfs. if you want to know exactly what she meant, just ask her here. She is very good about responding to questions.

Hope this helps,
