Accessibility
Accessibility of this website
This site is designed so that people can use its content and core functions with different browsers, input methods and assistive technologies.
Approach
The site uses semantic HTML, keyboard-operable controls, visible focus indicators, responsive layouts, text alternatives for meaningful images and language-specific page structures. Text and interactive controls are sized to remain practical at common zoom and text-spacing settings.
The implementation is reviewed against WCAG 2.2 Level AA requirements where they apply. This statement describes the design target and current testing approach. It is not a formal third-party certification or an assertion that every external resource meets the same standard.
Known limitations
Some third-party articles, social networks, video platforms and archived publications linked from this site are controlled by other organizations. Their accessibility can change independently of this website.
The Deque University completion certificates are original PDF records. Essential certificate information is also provided as HTML on the Certificates page so visitors are not required to rely on the PDF files.
Feedback
If you encounter an accessibility barrier on this site, please describe the page, the task you were trying to complete and the browser or assistive technology involved when relevant. I will use that information to investigate the problem.
