Assuming you're to produce a reflowable text ePub, you need to understand it's a completely different animal from the print edition. In brief, no page numbers, all text to have Paragraph and Character styles, no master pages, all images to be anchored.
Producing them is not intuitive, but you can easily learn if you take one of the online courses from Lynda.com, such as InDesign CC 2015: EPUB Fundamentals | Lynda.com
and Trainsimple.com, such as InDesign CC EPUB Fundamentals
There is an InDesign ePub forum.
Moved to InDesign EPUB forum.
Thank you Derek. I am always particular about styling my text so that's not too bad, I guess where I'm stuck is page sizes and if that is even relevant. Is a master text frame allowed? I will take a look at the Lynda course.
Bob - thanks for moving the thread.
No, page size is irrelevant - make it a convenient size so you get an idea of the page. I suggest you don't go straight to the real job but make up a few practice jobs so you get an idea of the issues. You'll probably have to make many more Paragraph Styles than you would normally have for a print document so keep your Styles Panel organised. Also learn to "crack open" the ePub so you can view the constituent parts.
Regularly use say iBooks or Adobe Digital Editions to view the ePub and the IDPF Validator to check your ePub: http://validator.idpf.org
If you want to view it on a Kindle, use the Kindle Previewer to convert the ePub to a mobi file.
Thank you. I can see I have a lot to learn.
Why would you have to make more styles for an EPUB than for a printed document, wouldn't they directly translate, chapter heading style, basic paragraph style, or am I really giving away my ignorance here?
Reflowable text ePubs are kind of HTML websites. You may know you can't have carriage returns for line spacing. So when, for example, you have the title page you may have to have separate paragraph styles for the title, author and imprint (with line spacing indicated in the styles) and that just for that page alone.
Also you'll need ToC styles probably taken from the chapter headings.
With ePubs you have an internal and an external ToC.
Ok - I never use carriage returns for line spacing anyway, I always define it in the style. But thanks for the HTML comparison, that helps. Don't know what an imprint is but I won't trouble you anymore, I will look at the Lynda course! thank you
I meant the Publisher's name.
You're not troubling me!
