Identify common accessibility issues and dive into the code, discussing how to create accessible web pages by using proper focus techniques, semantics, and design.


Accessible websites are built with robust focus techniques, proper semantics, and thoughtful design. Focus techniques, including the use of tabindex and JavaScript’s focus method, enable users to navigate websites without a mouse. Proper semantics, such as headings, labels, regions, and tables, allow users to effectively navigate and understand web content. The use of color and other design considerations impact users with low vision and other disabilities.

Starting with the basics, accessibility best practices are presented, identifying issues that prevent users from interacting with web content. Code samples are provided to demonstrate the impact of accessibility issues and their resolution. Advanced topics are explored, including ARIA, form errors, complex widgets, live regions, and single page apps.


  1. Understand the basics of web accessibility evaluation
  2. Learn how to correct common accessibility issues
