If Readium is based on Chrome code base, I have to wonder if this issue is rooted in Chrome instead of Readium or GPB.Readium is a free Chrome browser extension for reading ePub eBooks. See my previous question here: How well does Google Play Books support page-oriented css? (i.e., page breaks) ). Let me mention that Google Play Books also has problems with regard to css related to page size. I would worry about whether this issue shows up on mobile devices. But resizing is something you usually do on a PC browser, not a mobile device. I have noticed that some apps have resizing flakiness. That is still a sliver of reading audience. Update: I see that Bluefire has released an ios reader based on readium. I assume it means you have also tested on Google Play Books. If you support ibooks and ADE, that's covering a lot of ground. But I never had a use case for supporting Readium for epubs. I'm aware of and have occasionally tested things on Readium. I don't have much ability to answer your question (especially without seeing your code or knowing the required space in the viewport to hide or display).
