Screen readers and page structure
Pages use landmark regions and one ordered heading structure per page, so a screen reader can move by heading or jump straight to the main region. Expandable questions and menus report their open state.
Forms and error messages
Every field has a visible label that is programmatically associated with its control. Invalid fields are marked for assistive technology as well as visually, and the message says what to correct rather than only that something is wrong.
Zoom and reflow
Layouts are built in relative units and reflow to a single column, so text can be enlarged or the window narrowed without content being cut off or requiring horizontal scrolling.
Motion
Movement is limited to short functional transitions. If your system asks for reduced motion, those transitions are switched off rather than merely shortened.
