Accessibility

We design the Corpora site for keyboard access, readable contrast, small screens, text zoom, and reduced motion. Figures have text descriptions; mathematical notation includes MathML for compatible assistive technology.

What to expect

Use Tab to move between links and controls, Enter or Space to open worked solutions, and the skip link to reach the main content. Pages reflow on narrow screens. Printable examples have a dedicated print layout and a text-based solution key.

Scope and limitations

Our target is WCAG 2.2 Level AA. Automated checks cover only part of accessibility. This is not a conformance certification. Mathematical figures, screen-reader pronunciation, printable PDFs, the AMP app, and third-party payment or sign-in pages may need different accommodations.
