Website Accessibility v2 by Jon Kuperman on Frontend Masters was a fantastic course to get started on improving sites. Accessibility was overlooked on previous projects I was involved in but now I know what to do going forward.

I just completed "Website Accessibility, v2" by Jon Kuperman on Frontend Masters! And I realize how terrible I did accessibility as a frontend engineer in the past. I am already applying everything I learned in this course to my everyday work.
