Learning access
The interface includes a skip link, semantic landmarks, visible keyboard focus, responsive navigation, labeled code fields and a light color scheme. The mobile navigation supports Escape and focus containment. Text explanations accompany runnable examples.
Known limits
Selected keyboard and responsive interactions have been smoke tested. A full audit across screen readers, browsers, zoom levels and assistive technologies is not complete. We do not claim WCAG certification. Embedded examples can contain deliberate mistakes for exercises; challenge feedback is not a complete accessibility audit.
