Accessibility statement
We want every reader to be able to use the guides, whatever device, browser or assistive technology you use.
Updated October 18, 2026Our goal.
We work toward the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. This is a goal we test against, not a certification.
What you can change.
The accessibility button in the lower right corner opens settings for text size, text spacing, a readable font, higher contrast, stopping motion, underlined links, a stronger focus outline and a reading guide. Your settings stay on for your next visit.
Every menu, dialog, photo viewer and form works with a keyboard. Press Escape to close any open panel. The site also follows your device setting for reduced motion.
Known limitations.
The guides were written in 2013. Some photos carry short descriptions that repeat their caption instead of describing each photo, and the videos rely on YouTube's own captions.
Report a barrier.
If something on the site does not work for you, tell us the page and what happened, and we will fix it or send you the information another way.
