If you are familiar with accessibility in HTML and CSS, then you are good to go in a React application as well. Most of the rules still apply. But you may need to write it a little differently, and consider other things in addition, which we will discuss in more detail in this talk.
After the talk participants will have a understanding on how to write react code with accessibility in mind, how to work with DOM and Virtual DOM, how to test with keyboard and screen reader to make future as well as existing apps more accessible.
