Accessible Touch Interactions
1. Introduction
In today's mobile-first world, creating accessible touch interactions is crucial for ensuring all users can effectively navigate and use web applications. This lesson covers the principles of accessible touch interactions, including key concepts, best practices, and practical code examples.
2. Key Concepts
