Through practical tips and examples, Accessible EPUB 3 takes you inside the EPUB 3 format and explores how you can enrich and enhance content for all readers. Author Matt Garrish demystifies the process of making content easier to access, demonstrating how accessible practices are intertwined with standard content best practices. Among many techniques, this guide will teach you how to: Add structure and meaning to your publications to make them more usable by accessible technologies Tailor EPUB Navigation Documents for readers requiring either full or reduced navigation Create media overlays to synchronize human narration with text display Improve text-to-speech playback by adding SSML, PLS lexicons, and CSS3 Speech functionality
