Room for different ways to learn.
The prototype uses semantic headings, labelled inputs, keyboard-operable controls, visible focus states and feedback announced through status regions. A skip link moves directly to the main content. Layouts adapt to small screens and support reduced-motion preferences.
Keyboard use
- Use Tab and Shift+Tab to move between links and controls.
- Press Enter or Space on a button. Select a cell using its labelled button in a cell-selection exercise.
- Use the Search lessons button, or Ctrl+K / Command+K, to open search. Press Escape to close it.
- On a small screen, open the lesson navigation or menu with its summary control.
Tables and formulas
Worksheet examples include column letters and row numbers. Cell selection buttons announce the cell address and its contents. The formula input is separate from the worksheet, so you do not need to use a drag gesture to enter a formula.
Review status
The structure and controls have received automated and source-level checks. Formal WCAG conformance, screen-reader testing and testing across devices have not been completed. Further accessibility review is part of public launch preparation.
