Description
Note. Our course material is continually evolving. This course will be updated for free throughout 2025 and is the one stop shop for everything you need to begin building accessible websites. This is the best online web accessibility course available at a very affordable price.
Course code update - The course code has moved from GitHub to CodePen in a simpler, easier to navigate format.
This course is designed to teach you the fundamentals of web accessibility and how to apply those techniques to websites that you create. The modules are organised into categories grouping accessibility techniques to the relevant parts of a web page.
Each lecture explains one accessibility concept only and after every lecture there is a quiz to complete followed by the end of module activity applying all you've learnt onto a demo website. Most lectures are approximately 5 minutes long with no lecture being over 10 minutes in length.
You will learn:
An overview of web accessibility guidelines and WCAG 2.2
Build the structure of a page using a skeleton of accessibility support
Create content in an accessible way
Improve the structure of web forms using accessibility best practice error handling and validation patterns
Apply accessibility techniques to a demo website hosted on CodePen
This course gives you practical reusable patterns and best practice accessibility examples to apply to your projects. Web accessibility is fast becoming a required skill when developing for the web. The accessibility guidelines can be difficult to understand and challenging to apply. It's often left up to developers to try and do their best making content accessible by attempting to read and understand very complex technical guidelines.
Employers are looking for developers with an edge, web accessibility is that edge. Understanding how people with disabilities navigate a website and how you can make the experience better will set you apart from other developers. If you work in website or software development, UX or UI design in any frontend or backend technology this course is for you.
Web accessibility is more important than ever with more and more services are moving online. Unless these services are accessible the web can become a huge barrier for people with disabilities rather than a great opportunity to help with independent living.
Who this course is for:
- Developers who want to get hands-on and really understand and become familiar with web accessibility and common accessibility patterns for the websites and web applications they build.
- UI designers who need to understand the accessibility constraints for building web UI's.
- Software architects and business analysts who want to build in accessibility requirements early in the decision making process.
Instructor
I'm the founder of CANAXESS and a career developer who has worked on the web since its earliest days. I publish practical guidance, speak at conferences worldwide, and share commentary across blogs and social platforms.
I hold professional accessibility certifications, multiple software degrees, and I've authored university level accessibility units in Australia. I've worked as a front-end and back-end engineer, an accessibility auditor, and a specialist consultant to major governments and global brands, helping teams ship products that real people with disabilities use.
Most importantly, I teach you to do it too. If you are tired of vague advice, unhelpful courses and failed audits, you'll find clear steps with me. I'm incredibly proud of the 16,000 students who have taken my courses. My approach is practical, code-level, and jargon-free. My goal is to help you become the accessibility expert on your team, with techniques that stand up in audits and in production.
If you want real skills, not theory, you've found the right instructor. Together we'll build with web accessibility in mind following WCAG criteria and WAI-ARIA patterns, and assess with confidence using repeatable processes you can follow. Clear language, zero fluff, and examples you can use the same day.
Let's work together to help you become an accessibility expert.
