Web Accessibility (Udacity)
Developing with Empathy. 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.

This course is also featured in our Full-Stack Web Developer Nanodegree program.


Not every user approaches their applications with the same abilities. Whether it’s age, vision concerns, limited hearing, a broken arm, or other limitations, everybody deserves access to their apps. This course dives into the why and how of making web applications accessible. As a bonus, accessible sites also tend to be more usable for everybody!


What You Will Learn


Lesson 1

Overview

- Use a screen reader to try out ordinary form elements and add markup to make them work even better.

- Understand the accessibility tree the browser constructs from the DOM.


Lesson 4

Semantics Extras

- Dive deeper into the screen-reader experience to add hyper-fast navigation.

- Learn how to arrange headings and label links so screen reader users can fly through your pages!

- Call out “landmarks” into your page to speed up navigation even more.


Lesson 5

Semantics - ARIA

- Move beyond the native elements of HTML into building custom controls and interactions.

- Accessible Rich Internet Applications (ARIA).
