Accessibility

Using the site

• Use the “Skip to main content” link at the start of the page to bypass repeated navigation.
• Links, buttons, forms, and lesson answer disclosures support keyboard operation and visible focus.
• You can zoom text and use narrow layouts. We respect your device’s reduced-motion preference.
• Optional storage is not required to read lessons, browse the catalog, or view released lot information.

Known limitations

Third-party laboratory documents, downloadable PDFs, and linked external resources may not offer the same accessibility as our HTML pages. Dense operational tables may require horizontal scrolling. Full assistive-technology testing of every authenticated workflow and third-party document is still in progress.
