Introduction
What Is Web Accessibility?
Web accessibility means ensuring that websites, tools, and technologies are designed and developed so that people with disabilities can use them. More specifically, people can perceive, understand, navigate, and interact with the Web.
Accessibility is essential for developers and organizations that want to create high-quality websites and web tools, and not exclude people from using their products and services.
Why It Matters
The Reality
Over 2.2 billion people globally have a vision impairment. Without accessible design, entire populations are shut out of digital services.
Accessibility is not just an ethical obligation — it is increasingly a legal requirement. Laws such as the Americans with Disabilities Act (ADA) and the European Accessibility Act (EAA) require digital services to be accessible.
Our Focus: Visual Impairment
This course specifically focuses on visual impairment — the most common type of disability affecting web usage. We will cover:
- Total blindness (screen reader usage)
- Low vision (magnification, contrast needs)
- Color blindness (color independence)
Tip: Try the interactive simulations on the Experience page to feel these barriers firsthand before continuing this course.
