What They're Saying

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.

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!

Quick and rich course about website accessibility that fills our toolbox from the beginning. With small details that are easy to implement in our development process without increasing too much the overall time, a win-win. Jon Kuperman delivered a five star course once again.
