Accessibility
Courses, made for everyone
Zunderwork ships with a deep set of personal reading preferences, visual aids, and authoring guardrails. So when learners arrive with different needs, the platform meets them where they are.
Personalized for every learner
More than twenty preferences, from font size to color blind filters, are saved per user and follow them across devices.
WCAG 2.1 from the ground up
Required alt text, scoped table headers, focus indicators, semantic headings, keyboard navigation. Authors get accessibility for free.
Reading aids that actually help
Reading guides, masks, magnifying glass, dyslexia preset, and a one-tap dyslexia-friendly setup, all built in.
Reading preferences
Twenty plus controls, one toolbar
Learners adjust how a lesson reads without leaving the page. Settings persist on their account, with localStorage fallback for guests.
Font size
Four steps from small to extra large for comfortable reading.
Font family
Default, serif, or a dyslexia-friendly typeface for easier word recognition.
Line spacing
Compact, default, or relaxed line height to reduce text crowding.
Letter spacing
Open up the space between letters to ease tracking.
Word spacing
Increase space between words for better readability.
Paper color
Pick from presets or any custom background color.
Text color
Customize text color with a live WCAG contrast meter.
High contrast
Boost contrast in one click for low-vision support.
Brightness
Adjust page brightness independently from the device setting.
Saturation
Tone colors down for sensitivity, or up for clarity.
Color blind filters
Protanopia, deuteranopia, or tritanopia simulation overlays.
Zoom
Six zoom levels from 100% to 200% without breaking layout.
Underline links
Make links always visible with an underline.
Highlight links
Give links a background color for extra visibility.
Force left align
Align all text to the left for consistent reading direction.
Highlight headings
Visually emphasize headings for better navigation.
Reduced motion
Pause loops, marquees, and autoplay animations across the platform.
Pause animations
Temporarily stop all animations and transitions.
Stop sounds
Silence platform audio cues with one toggle.
Reading guide
A focus bar that follows the cursor and highlights the current line.
Reading mask
Dim everything except the line being read to reduce distraction.
Magnifying glass
A floating lens that magnifies whatever the cursor is on.
Big cursor
Make the cursor easier to track at a glance.
Larger click targets
Enlarge buttons and links for easier clicking.
Keyboard navigation
Show hints for keyboard shortcuts.
Hide images
Strip decorative images for distraction-free reading.
Authoring guardrails
Accessibility shouldn't depend on the author remembering
The course builder enforces the basics, so what authors publish is accessible by default.
Required alt text
Every image block requires a description, or the author must explicitly mark it as decorative.
Live contrast meter
When picking custom colors, the editor shows the WCAG ratio in real time and warns when AA fails.
Semantic structure
Heading levels stay in order, table headers carry scope, and lessons use real landmarks for screen readers.
Visible focus everywhere
Every interactive element has a focus-visible outline. Keyboard users always know where they are.
