Accessibility statement

Updated October 6, 2026

We aim to make the guides and tools usable with a keyboard, screen reader and a range of screen sizes. This statement describes implemented features and known limits; it is not a claim of independently certified conformance.

Reading and navigation features

• A skip link leads to the main content.
• Pages use descriptive headings and a visible keyboard focus indicator.
• Article diagrams have text alternatives and explanations in the article.
• The footer offers standard, large and extra-large text controls.
• Guide summaries have an optional browser read-aloud button.
• Menus and FAQ answers use native disclosure controls.

Tables and tools

Wide reference tables may need horizontal scrolling on small screens. Tool inputs have labels. A diagram is accompanied by textual explanation so its meaning does not depend solely on color. The core articles and policy pages remain readable without JavaScript; interactive filters and calculations require it.

Known limits

Browser speech synthesis and available voices vary by device. Third-party source documents may have accessibility limitations outside this site’s control. Automated checks and responsive reviews cannot identify every barrier; assistive-technology testing and reader reports are still needed.
