I learned that it's impossible to make Custom storefront on new DPS(Digital Publishing Solution).
But I want to make entrance page with HTML5, so I searching any other method.
What I want to do is below.
1. I want to line up title and thumbnail of "collection" at first page of app.
2. I want to line up title and thumbnail of "article" in any "collection" at detail page.
I know that I can't use API of old DPS.
But I think that there are another method of get "collection" and "article" information from server.
if there aren't method of getting these information, I must change HTML source when I publish new "collection" or "article" everytime ...
