For real, you did something with this course Jon Kuperman my mind is blown by how much I’ve been underutilizing these very powerful tools. Well done!

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.

This was a great overview of Chrome Dev Tools and I feel much more confident using it for optimizing websites and not just console.log 😆

Developers who are learning to code or are early in their career often don't have much knowledge of working with the DevTools. Being able to work with the DevTools can help you tremendously.

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.
