What we do
- We follow the Web Content Accessibility Guidelines (WCAG) 2.2, level AA, as our guide.
- Text contrast of at least 4.5:1, visible keyboard focus and labels on every form field.
- All content works with a keyboard and without JavaScript.
- Images have text alternatives; key information is never only in an image.
- Nothing moves if you ask your device to reduce motion.
What we know is not perfect
We have not had a full independent audit, so we do not claim full conformance. Some drawings and model images are hard to describe in text; ask us and we'll explain them.
Tell us about a problem
If something does not work for you, write to [email protected]. We reply the same business day and can send the information in another format.
