A Practical Guide to Accessible Digital Publishing
Accessibility is not optional. Learn how to make your digital publications WCAG compliant, reach a wider audience, and meet legal requirements.
A Practical Guide to Accessible Digital Publishing
Over one billion people worldwide live with some form of disability. When your digital publications are not accessible, you are excluding a significant portion of your potential audience. Beyond the ethical case, accessibility is increasingly a legal requirement in many jurisdictions, and it directly improves the experience for all readers.
This guide covers the practical steps you can take to make your digital publications accessible, whether you are publishing flipbooks, reports, or marketing materials.
Why Accessibility Matters for Publishers
Accessibility is often treated as a compliance checkbox. In reality, it is a quality standard that benefits everyone. Accessible content is easier to navigate, easier to read on different devices, and easier to consume in different contexts.
Consider these scenarios that affect all readers, not just those with permanent disabilities:
A reader in bright sunlight needs sufficient colour contrast to read your content
A commuter on a crowded train needs to navigate without precise mouse clicks
A reader with a temporary injury may be using keyboard-only navigation
A non-native speaker benefits from clear heading structure and logical content flow
When you design for accessibility, you design for real-world conditions.
WCAG 2.2 AA: The Standard to Meet
The Web Content Accessibility Guidelines (WCAG) 2.2, published by the W3C, are the internationally recognised standard for web accessibility. Level AA is the target most organisations should aim for. It covers four principles:
1. Perceivable
Content must be presented in ways that all users can perceive.
Text alternatives: Every non-text element (images, charts, icons) needs a text description that conveys the same information
Colour contrast: Text must have a contrast ratio of at least 4.5:1 against its background (3:1 for large text)
Content structure: Use proper headings (H1, H2, H3) in a logical hierarchy so screen readers can navigate by section
Media alternatives: Video content should have captions; audio content should have transcripts
2. Operable
Users must be able to navigate and interact with your content using different input methods.
Keyboard navigation: Every interactive element must be reachable and usable with a keyboard alone
Focus indicators: When a user tabs through content, a visible focus ring must show which element is active
No time limits: Do not auto-advance pages or dismiss content on a timer unless the user can pause or extend it
Skip navigation: Provide a way to skip repetitive elements and jump to main content
3. Understandable
Content and interface behaviour must be predictable and clear.
Readable text: Use clear language, define technical terms, and keep sentence structure straightforward
Consistent navigation: Navigation patterns should be the same across all pages of a publication
Error prevention: If your publication includes forms (like lead capture), provide clear labels, instructions, and error messages
4. Robust
Content must work with current and future assistive technologies.
Valid markup: Use semantic HTML elements correctly so assistive technologies can parse your content
ARIA attributes: Where standard HTML is insufficient, use ARIA labels and roles to provide context
Testing: Regularly test with screen readers (NVDA, VoiceOver, JAWS) and keyboard-only navigation
Common Accessibility Failures in Digital Publishing
These are the issues we see most frequently in published content:
Images Without Alt Text
Every image in your publication should have descriptive alt text. Decorative images can use an empty alt attribute, but informational images need text that conveys their meaning. A chart showing quarterly revenue should not have alt text that says "chart" - it should describe the data the chart presents.
Poor Colour Contrast
Light grey text on a white background may look elegant, but it fails contrast requirements and is genuinely difficult to read for many people. Use a contrast checker before finalising your design. The minimum ratio is 4.5:1 for body text.
Missing Heading Structure
Screen reader users navigate by headings. If your publication uses visual styling (larger, bolder text) instead of proper heading elements, screen readers cannot build a navigation outline. Use H1 for the title, H2 for sections, and H3 for subsections - always in order, never skipping levels.
Inaccessible Navigation
If readers can only navigate your publication with a mouse, you have excluded keyboard users. Page turns, links, buttons, and form fields must all be operable with keyboard input alone.
Auto-Playing Media
Audio or video that plays automatically when a page loads is disorienting for screen reader users and disruptive for everyone else. Always give readers control over media playback.
How ZenFlip Handles Accessibility
ZenFlip builds accessibility into the flipbook format by default:
Keyboard navigation: Full keyboard support for page turning, navigation, and all interactive elements
Screen reader compatibility: Proper ARIA labels, roles, and live regions throughout the viewer
Focus management: Visible focus indicators that follow the user's position in the publication
Colour contrast: The default viewer theme meets WCAG 2.2 AA contrast requirements
Semantic structure: Content is rendered with proper heading hierarchy and landmark regions
Skip links: Readers can skip directly to main content
These features are enabled by default on every publication. You do not need to configure anything to get a baseline of accessibility compliance.
Testing Your Publications
Automated tools catch many accessibility issues, but manual testing is essential. We recommend this testing workflow:
Automated scan: Run your published flipbook URL through axe DevTools or WAVE to catch low-hanging issues
Keyboard test: Navigate your entire publication using only Tab, Enter, Arrow keys, and Escape. Every element should be reachable and usable
Screen reader test: Use VoiceOver (Mac) or NVDA (Windows) to read through the publication. Listen for missing labels, confusing navigation, and content that does not make sense without visual context
Contrast check: Verify that all text meets the 4.5:1 ratio using a tool like the WebAIM Contrast Checker
Mobile test: Confirm that touch targets are large enough (at least 44x44 pixels) and that the content is usable with screen magnification
Making Accessibility Part of Your Workflow
Accessibility should not be a final check before publishing. It should be part of your content creation process from the beginning:
Design phase: Choose colour palettes that meet contrast requirements. Plan heading structures before writing
Content phase: Write alt text as you add images. Use clear, concise language
Review phase: Include accessibility in your review checklist alongside brand consistency and factual accuracy
Publishing phase: Use a platform like ZenFlip that handles technical accessibility automatically
Post-publish: Monitor analytics for drop-off patterns that might indicate accessibility barriers
Accessible publishing is better publishing. It reaches more people, meets legal requirements, and produces content that works well for everyone.
