What They're Saying

Awesome course by Jon. I have been doing front end development for the past 10 years, and have worked on accessibility as part of code by following the guides and frameworks but I never had the insight into how it actually helps people with disabilities. This course was easy to follow, crisp and to the point. Highly, recommended for any front end developer.

I liked how he taught in a way that convinces us to not look at accessibility as a nice-to-have option, but something that must be taken into consideration. I also like how he gives students some small problems to solve to solidify what is taught.

I was surprised to know just how capable the DevTools are, and how resourceful they can be to debug and improve the performance of your applications.
Rohan Khalate
This course convinced me that implementing accessibility is a major step to being a better web developer.

Just finished the Website Accessibility, v3 course on Frontend Masters by Jon Kuperman. Honestly, I had heard of web accessibility before, but never truly explored it. This course opened my eyes to the real impact of semantic HTML, ARIA roles, focus management, and proper contrast. Huge thanks to Jon for sharing not just technical skills but also real-world experiences that made everything more relatable. Highly recommended for any frontend developer!
