Accessibility

This site aims to conform to the Web Content Accessibility Guidelines (WCAG) 2.1, Level AA. Good systems should carry everyone.

What’s in place

• Semantic structure — proper landmarks, one heading hierarchy per page, and a skip-to-content link.
• Keyboard navigation — every menu, link, and form works without a mouse, with visible focus indicators throughout.
• Color contrast — text colors are chosen to meet AA contrast ratios against their backgrounds.
• Reduced motion — if your system requests reduced motion, animations are disabled and the home-page video will not autoplay.
• Readable type — body text at a comfortable size and line height, in a column narrow enough to follow.
• Alt text — images that carry meaning have text descriptions; decorative images are hidden from screen readers.
• No text trapped in images — nothing important is communicated only through pictures.

Known limitations

Some older downloadable PDFs in the Field Guide Vault were built as slide decks and may not be fully screen-reader friendly. If you need any of that material in an accessible format, ask — it will be provided.

Tell me when it breaks

If any part of this site is hard for you to use, that’s a defect, not your problem. Write to christa@christaburger.com with the page and the difficulty, and it will be fixed as quickly as possible.
