Our goal
The site aims to make its static pages and browser tools usable with keyboard navigation, screen readers, zoom and small screens.
Current measures
- Semantic headings and landmark elements
- A visible-on-focus skip link
- Keyboard-operable navigation and form controls
- Text alternatives for informative graphics
- Responsive layouts without required horizontal scrolling, except wide data tables in scroll containers
- Labels and live result regions for tools
Known limitations
Third-party advertising and linked websites are not fully controlled by this site. Some complex tables may require horizontal scrolling on narrow screens.
