A lot of this site’s readers have reduced vision, reduced dexterity, or are reading on a phone at arm’s length. Accessibility is not a compliance exercise here; it is most of the audience.
What is built in
- Diagrams do not rely on color alone. The arteries, veins and lymph illustration distinguishes the three by line style as well as color, and each line is labelled in text.
- Every diagram carries a text description that conveys the same information as the picture.
- Visible keyboard focus on every link, button and expandable section.
- Touch targets of at least 44 pixels on interactive elements, including the expandable questions.
- Large body text with generous line spacing, and a reading width that does not run edge to edge on a wide screen.
- Comparison tables scroll inside their own frame on a narrow screen rather than forcing the whole page sideways.
- Real headings in order, one H1 per page, so screen reader navigation works.
- No autoplay audio or video, no pop-up newsletter overlays, and no banner that follows you down the article.
- Urgent care guidance is placed near the top of pages where it matters, not below the fold.
Standard we are working to
We aim at WCAG 2.1 Level AA. We have not had an independent audit, and saying we are “fully compliant” without one would be the kind of unverified claim this site avoids elsewhere. Where we fall short, we would rather know.
Known gaps
- PDF worksheets are not published yet; when they are, they will be tagged for screen readers and paired with an HTML version.
- Videos are not published yet; when they are, they will carry captions and a transcript.
Report a barrier
If something here does not work with your screen reader, keyboard, magnification or browser settings, please tell us through the contact page. Describing what you were trying to do and what happened is more useful than a technical report, and we will try to fix it and tell you when we have.
