What are the good resources to learn PWA and GraphQL? For PWA do we need to use React js or can we do that without using any framework?

Neha Sharma Thank you for your answer and time.

Hi Neha, Thanks for doing the AMA for us. I have the following two questions. 1) What are good resources to learn the accessibility of web applications? I am using this tutorial https://www.w3.org/WAI/tutorials/ which contains how to improve the accessibility of the Menu bar, Page structure, Image Carousel, Tables and Forms . Is this sufficient? 2) How to support web application to the blind & color-blind users. How to do that ?
