Thanks for the advice. My learning process depends on: Sigil, PageEdit, Sigil Guide (which is epub 3), PageEdit Guide (which is epub 2), w3schools.com, and this very helpful MobileRead forum. With all this, I’m sure I’ll soon be able to make my epub 3 files backward compatible with epub 2, for example, by using the NCX file and avoiding things that don’t work in EPUB 2. Thanks again for pointing me in the right direction.
