Our goal
We aim for this site to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA.
What we’ve done
- Semantic page structure with landmarks, a logical heading order, and a “skip to main content” link
- Full keyboard access with clearly visible focus indicators
- Text and interface colors chosen to meet AA contrast ratios in both light and dark themes
- Descriptive text alternatives for meaningful images
- Form fields with visible labels and error messages that are announced to screen readers
- Support for your device’s reduced-motion setting, which turns off animations
- Layouts that adapt to small screens and to text zoom of up to 200%
- Pages that remain usable with JavaScript turned off
Known limitations
We test with automated tools and by hand, but no website is perfect. If something on this site is difficult for you to use, we want to hear about it.
