This resource is part of the Teach Access Initiative, and provides best practices for making accessible mobile and web apps. This tutorial currently provides basic training for developers and designers, with more disciplines to come! If you are new to accessibility, you’ve come to the right place - the following material will help you get a solid footing on accessibility via hands-on exercises and useful reference guides.
In this section, you’ll learn a few key user interface implementation techniques that will ensure you are building experiences that anyone can use. The world of accessibility is vast and diverse, so this tutorial won’t cover everything - but it will get you started in the right direction and provide you with some basic best practices for writing accessible software.
