Our commitment
We aim for this site to meet the Web Content Accessibility Guidelines (WCAG) 2.2, level AA. Accessibility is part of how pages are designed and built, not something added at the end.
What we've done
- Semantic landmarks, one main heading per page and a logical heading order.
- A "Skip to content" link and visible focus outlines on every interactive element.
- Text contrast of at least 4.5:1 and touch targets of at least 44 by 44 pixels.
- Descriptive alternative text on informative images; decorative images are hidden from screen readers.
- Carousels can be paused and operated by keyboard; accordions and the Symptom Finder work without a mouse.
- Animations are reduced or turned off when your system asks for reduced motion.
- Form fields have visible labels, and errors are announced and linked to their fields.
- Layouts reflow from 320px wide phones to large desktop screens without horizontal scrolling.
Known limitations
- Some illustrations contain fine visual detail that a short text alternative can only summarize; the step text always carries the full instructions.
- Animated diagrams on printer type pages are described in text, but the animation itself is not narrated.
- Optional third-party tools that load after consent are outside our direct control.
