Display dynamic html content like an epub/ebook, without converting html to epub format?

I want to create a responsive, mobile optimized reading experience similar to an epub/ebook reader, like the Kindle app, or iBooks, using dynamic html as the source.

Imagine a long article or blog post that requires a lot of vertical scrolling to read, especially on a small mobile device. What I would like to do is break the long page into multiple full-screen sections, allowing the user to use left/right navigation arrows and/or the swipe gesture to "page" through the article.

There are many JS libraries available that can create a "slide show" or "carrousel" of pre-defined slides (using divs or other container elements). But I want the text and html content to dynamically re-flow to fit any device viewport and still be readable... just like an epub/ebook user interface, like the Kindle app or iBooks. So, for the same article, there would be many more "pages" on a phone than there would be on a tablet or desktop viewport, and those "pages" would need to be dynamically created/adjusted if/when the viewport size changes (like switching from portrait to landscape on a mobile device).

Here is an example of a javascript .epub reader: epub.js

... notice the responsive behavior. When you resize your viewport, all the text re-flows to fit the available space, increasing or decreasing the total number of "pages". The problem is that epub.js requires an .epub file as its source.

What I want is the same user interface and functionality for an html page.

I have searched and searched for some kind of library that can do this out of the box, but haven't been able to find anything.

I realize that I could use a conversion script to convert my html page into an .epub file, and then use epub.js to render that file within the browser, but that seems very round-about and clunky. It would be so much better to mimic or simulate the .epub reader user experience with html as the direct source, rendering/mimicking a client side responsive ebook user experience.

Does anyone know if something like this already exists, or how I could go about building it myself?

The crucial functionality is the dynamic/responsive text-reflow. When the viewport dimensions are reduced, the text/content needs to reflow to the next "page" to avoid any need for vertical scrolling. I don't know how to do this efficiently. If I were to code it myself, I might use something like the jQuery Columnize plugin, setting all columns to width: 100vw; height: 100vh, so that each column is like a "page", and then figuring out how to create a swipe UI between those "pages".

Any help is much appreciated!
