FXL & Reflowable

[gautierchomel]

FXL-A11Y working group has drafted a state of the art documentation on EPUB Fixed Layout Accessibility.

Still one accessibility issue remains witch is the one related to ability to change font family, size, spacing as well as background and text colors. This is a critical issue for persons with low vision or cognitive disabilities.

Different solutions have been proposed to allow a way to adapt text and layout within a fixed layout EPUB but from a Reading System perspective it will not be possible to implement all solutions.

This issue tries to list different proposals to allow reflowable text into fixed layout and estimate which ones are the most susceptible to be used in an industrial context.

• Fallbacks
• Multiple Rendition
• Hybrid
• Guided navigation
• Visual to textual
• Region based navigation
• JS in files
• SVG
• A Reading System could present a textual reflowable view based on TTS practices. See Best practice document: Extracting data for TTS and a "reader mode" #69
