Experience
Accessibility
Most accessibility guidance tells you what to fix. This site lets you feel why it matters. Every page is a working demonstration — toggle barriers on real content, experience the impact through simulations, and learn the standards and code that make digital learning work for every student.
Built for instructional designers, course developers, and learning teams who want to move beyond compliance checklists and understand accessibility and Universal Design for Learning as a design practice — not an afterthought.
What is Accessibility?
Designing products and content so that people with disabilities can perceive, understand, navigate, and interact with them effectively.
EXPLORE FOUNDATIONSWhat is UDL?
Universal Design for Learning is a framework for designing flexible learning experiences that accommodate the widest range of learner variability from the start.
EXPLORE UDL FRAMEWORKHOW THIS SITE WORKS
Each page has a sticky banner — switch between the well-designed version and the poorly designed version in one click.
View inaccessible and accessible patterns side by side to understand what changed — and why it matters.
When barriers are active, look for the "Fix available" button on each demo. It reveals the WCAG criterion, explanation, and before/after code.
