Differences in creation of epub 2 and epub 3

[stefanias90422857]

Hello everyone.

I am currently able to create ebooks in epub 2 format only.

I took a "test", starting from an InDesign file worked for epub 2, containing text and images: I tried to export this file to epub 3 and I saw that the result is not acceptable (for example, the images are overlaid with the text).

Can you tell me how I have to vary the processing, compared to what I usually do for epub 2, if I need to obtain an epub 3?

Or, if there are too many differences, I accept the advice to take a training course! I'm just trying to orient myself.

Thank you and have a nice day

Stefania

What version of InDesign? What operating system? Is it fixed layout or reflowable? How are you viewing this EPUB?

I'm using InDesign CC 2019 on macOS High Sierra. When I export in epub 2 (reflowable), the file is perfectly fine (at least, I make some changes in Sigil), and then I vizualize it through iBooks or Calibre.

Regarding epub 3 (fixed layout), as better explained in my first post, I'm a newbie, just trying to figure things out! Thanks.

You cannot compare fixed layout and reflowable. They are completely different.

Fixed layout must be viewed in a compatible reader app (Books on Mac or iOS is the best) and fonts must be Opentype.

Use ePub 3 for Reflowable ePubs as well as FXL ePubs.

Producing Reflowable ePubs is not intuative, I suggest you take a course, such as those on Linkedin Learning by Anne-Marie Concepcion (you can get 30-days free access).
