Accessibility is critical for the success of your book.
In general, your work should be available to all readers no matter what their device, situation or abilities are.
An empty Superbook container meets nearly all acessibility guidelines per WCAG 2.1 (2018), but there are still some areas where the challenges of the longform creep up. Prevent a reader from completing your book.
To help readers glide through your work without interruption, make sure that you follow the below given accessibility guidelines:
Never hardcode values for text size such as using
24pton your book. Use only viewport units like
4vwto make sure the body of text scales accurately across all devices thus covering maximum readership potential between mobile phones and television sets. Done right, a Superbook can be displayed correctly on an Apple Watch as well.
Do not hardcode page numbers within the contents of your book. Use
.bookrcinstead to display page numbers on publshing. Page numbers can also be enabled via the online editor console on Bubblin.
