What is the course about?

Web Accessibility
The course Web Accessibility is an online class provided by Udacity. The skill level of the course is Advanced. It may be possible to receive a verified certification or use the course to prepare for a degree.

In this course you’ll get hands-on experience making web applications accessible. You’ll understand when and why users need accessibility. Then you’ll dive into the “how”: making a page work properly with screen readers, and managing input focus (e.g. the highlight you see when tabbing through a form.) You’ll understand what “semantics” and “semantic markup” mean for web pages and add ARIA markup to enable navigating the interface with a range of assistive devices. Finally, you’ll learn styling techniques that help users with partial vision navigate your pages easily and reliably.
