The following basic steps can be useful if you want to produce epub books for children:
- Download Calibre application and convert your book from pdf to epub format. Do not expect a nice result after conversion. It will be just a starting point from which you have to work on
- Download Sigil and open your epub book to clean it up, add images, text, etc.
- Learn how to zip/unzip epub files, work with xhtml files inside an epub, and zip it again.
- Add interactivity using JavaScript. For instance, tapping on any word from the text, the associated image fades in as a popup, tapping on the image again to dismiss it. Same effect with audios and videos.
- Add other EPUB3 and HTML5 functionalities. For instance, objects moving around when you change your iPad orientation, etc.
Enjoy!
