PUBLICATION DETAILS
Accessibility
Reading controls that are easy to find.
Text you can enlarge
Article text starts at 22 pixels and increases to 26 pixels with the Larger text control. The site also works with browser zoom. Line length, spacing and distinct headings help divide longer explanations into readable sections.
A keyboard route through the page
The first Skip to content link reaches the main reading area. Question panels use native disclosure controls. Search and reading-type filters use labeled form controls, and links have visible focus treatment. Article contents provide direct paths to sections and source notes.
Mobile and verification
Layouts are checked at narrow mobile and desktop widths, including larger text. Automated accessibility checks and keyboard interaction tests help find errors, but cannot guarantee every browser and assistive-technology combination. No medical information is hidden behind a signup, quiz or animation.
Other ways to browse
Guides and Reviews provide static lists if you prefer them to search. The footer links to the complete library, source register and sitemap. Every article includes related reading and a source list without needing an account or saved preferences.
