Resources for Learning Web Accessibility

Web accessibility is a vast and multi-faceted topic, so it can be easy to feel overwhelmed when you’re trying to learn how to build accessible websites.

If you’d like to learn about accessibility but don’t know where to start, this is the post for you.

We've compiled a list of resources that we think are useful when it comes to learning web accessibility. Whether you learn best from official documentation, online courses, blog posts, or written tutorials, we've got you covered.


Let's start with some official documentation. Fair warning: Be prepared for some acronyms.

The World Wide Web Consortium (W3C) maintains web accessibility standards called the Web Content Accessibility Guidelines (WCAG). Version 2.2 was released on July 20, 2023, and is the latest version at the time of writing. If you've ever been told that your site needs to be "WCAG-compliant", these are the standards your site will need to meet.

Part of the W3C is the Web Accessibility Initiative (WAI), which, as the name suggests, develops standards and materials for web accessibility. One of these standards is the Accessible Rich Internet Applications Suite (WAI-ARIA, or just ARIA), which is particularly useful for parts of a website that are dynamic (e.g., UI elements that utilize JavaScript).

Helpful sites

The official standards can be a bit difficult to parse sometimes. Here are some links to tutorials and other sites with explanations that can be easier to understand:

Online courses

If you learn best via video and coding along, then these courses (both free and paid) are excellent options:

  • Testing Accessibility (paid) – a course by one of the most well-known members of the field, Marcy Sutton, that teaches accessibility concepts and has valuable modules on how to test accessibility.

  • Practical Accessibility (paid) – a course by another industry expert, Sara Soueidan, that teaches accessibility from the ground up, including how to navigate the official standards documentation.

  • A11ycasts with Rob Dodson (free) – a YouTube tutorial series that focuses on accessibility fundamentals.

  • Web Accessibility: Developing with Empathy (free) – a Udacity course built in collaboration with Google that teaches web accessibility basics.

Blog posts

If your learning style is more geared towards reading, then you may find these blog posts on a variety of web accessibility topics to be helpful:
