This my first post, so please bear with me
I am a lecturer and I am planning to write an browser-based ebook (including videos and pictures), accessible by my students, say, from Safari or Chrome. Is InDesign the right tool for the job?
Probably not. It can create Fixed Layout EPUB3 files which can be viewed in eBooks readers that support that standard. Currently that includes iBooks (Mac OS X Maverick and iPad), Kobo eBook readers, and the Readium plug-in on Chrome browsers. Support is increasing and other platforms may support it as well. But in general, InDesign doesn't create what you're looking for.
You could try building a website in Adobe Muse for use in web browsers.
Thanks for the super-quick reply! I will check Adobe Muse out. Cheers!
