Hey there. I published an ebook recently in epub 3 format using SIGIL. After submitting it for distribution, I checked the book's preview at ebooks.com and found that the font was changed to sans serif and there was no leading. It was a disaster to look at — like it had lost part of its css code.
Yet when I went to Kobo or Barnes & Noble, my previews there looked fine. Not spectacular, but closer to what I would expect to see.
Anyone know what might be going on based on your own experiences with online preview engines? (or perhaps that ebook retailer specifically?)
I'm still relatively new to publishing ebooks online, so I'd like to iron out the kinks before submitting more of my work to booksellers. I can't imagine anyone wanting to buy my book with a crappy preview like what I saw.
Thanks for any insights you can offer.
