ARIA roles in InDesign EPUBs

Improved Code
The code exported in EPUBs made with Circular Software contains the modern ARIA roles that are missing from InDesign.

The World Wide Web Consortium’s “Web Content Accessibility Guidelines“, (the W3C’s WCAG) are developed for web content, but they are also applicable to other forms of digital content – like ebooks.

ARIA roles are auto added to ebook sections and page markers and for styles we are encouraged to indicate use the h1-h6 heading levels plus these more descriptive HTML tags where appropriate for Paragraph Styles:

  • Sections
  • Headings
  • Sidebars
  • Citations
  • Block Quotes

For Images:

  • Figures

And for Character Styles:

  • Bold and Italic
  • Emphasis and Strong
