Yes — Atticus ePubs can meet key accessibility standards (WCAG AA) as long as authors use the available features correctly, including:
Adding alt text to all meaningful images and skip decorative images (both overusing and underusing alt text can make your ePub non-compliant).
Allowing text resizing. Atticus ePubs support text resizing by default, but forcing size through formatting workarounds can reduce accessibility.
Using reflowable content (default in Atticus).
Writing clear link text so hyperlink purposes are obvious. Avoid vague links like “click here” — make the destination clear.
Structuring chapters and headings properly for consistent navigation. Atticus automatically generates consistent navigation as long as content is organized into chapters and, where needed, subheadings.
Avoiding unreadable characters like upside-down text or excessive emojis.
For higher-level (AAA) requirements, some actions like ensuring high contrast on images, providing definitions for unusual words or abbreviations, and clarifying pronunciations are author responsibilities.
Following these best practices helps ensure your eBook is accessible to a wide audience.
