# Accessibility
|
|
|
|
Office Tools uses semantic controls, visible focus, keyboard-operable file
|
|
selection and the shared Toolbox light/dark/system preference. The main content
|
|
width is `min(100%, 90rem)` and layouts collapse without horizontal page
|
|
overflow on narrow screens.
|
|
|
|
Viewer adapters should preserve meaningful headings, paragraphs, lists and table
|
|
semantics where the source exposes them. Spreadsheet grids need labelled row and
|
|
column headers plus a non-visual cell description. Presentation navigation needs
|
|
an announced slide position and a linear text alternative for each slide.
|
|
|
|
Colour alone must not communicate selection, errors or diagnostics. Animations
|
|
respect `prefers-reduced-motion`. Imported images use source alternative text
|
|
when available and an explicit fallback when it is absent.
