IMO it's important that new concept of content will not be broken for reading system that not ready to support it yet.

Also, for extension of existed content how easier to let creator avoid duplication work (for example someone already created a normal comic book if he need to create the other one for vertical-scroll).

Base on this, I would like to see vertical scroll supported by https://w3c.github.io/publ-cg/guides/region-nav-markup.html, the benefit is we just need one version of content. For reading system that not ready to support it still can let user read this book comfortable.

How can user purchase two version of same comic just because one of them can support vertical-scroll and better for small screen but the other is definitely better for large screen?

For what it's worth, option #1 (reflow scroll-doc) rendered by Readium and EPUB.js:



Also, for the curious amongst us, here is a pretty-print of the "Readium WebPub Manifest" generated from Makoto's EPUB (the resource links are browsable):

Note that the above URLs link directly to the EPUB file in DropBox (i.e. non-exploded, whole zip file), so there may be some latency.

I am starting a new thread about vertically-scrollable manga.
Vertically-scrollable manga started several years ago, but it is about
to prevail.  However, different players use different formats now.

I made a few prototypes:

1) A single HTML version, rendition:layout=reflowable,

2) Multiple HTML file, rendition:layout=pre-paginated,


3) Multiple HTML file, rendition:layout=reflowable,


In my opinion, 1) is the best.  It does not use any EPUB-specific
features.  If you unzip this EPUB and click the HTML document, you
will get the same result.

I am wondering if 2) is actually asking for a non-conformant
behavior.  Should the document be rather resized so that it fits in
the screen?

My memo for promoting 1) is available at




I did this experiment more than one year ago.  I believe that a
consensus in the industry is strongly needed right now.

How do people feel?  Perhaps, this is a nice topic for the upcoming
workshop in Tokyo in September.
