Web Accessibility Workshop Notes
Building in accessibility from the beginning of the design and development process improves usability for everyone.
Here are some resources and tools that helped me learn more about Web Accessibility and the fantastic community of writers, designers and developers working on this topic. I prepared these notes for a workshop I led at UCLA. I hope it helps you explore this important field of study.

- Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.
- Large text is defined as 14 point (typically 18.66px) and bold or larger, or 18 point (typically 24px) or larger.
When it is not feasible to test every single page of a website you may need to focus on just critical and representational pages:
- site templates
- interactive forms
- dynamic content pages
- dialog modals and alerts
- Key entry and exit pages (including account login and recovery pages)
- Contact and help pages
- Pages that receive the most visits and traffic identified with analytics
