Intro to Web Accessibility
"The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect."
-- Tim Berners-Lee, W3C Director & inventor of the World Wide Web
62% of employees with a disability have an invisible disability or a disability that one cannot immediately identify upon meeting a person.
What is Web Accessibility?
Web accessibility is ensuring there are no barriers that prevent interaction with, or access to websites on the web by people with disabilities. When sites are correctly designed, developed and edited, generally all users have equal access to information and functionality.
Who is Web Accessibility For?
Web accessibility benefits people with permanent physical challenges and people with changing abilities due to aging or temporary disabilities.
Web accessibility also benefits people without disabilities, for example:
- People using mobile phones, smart watches, smart TVs, and other devices with small screens, different input modes, etc.
- Older people with changing abilities due to aging
- People with “temporary disabilities” such as a broken arm or lost glasses
- People with “situational limitations” such as in bright sunlight or in an environment where they cannot listen to audio
- People using a slow Internet connection, or who have limited or expensive bandwidth

Why is Accessibility Important?
The Web is an increasingly important resource in many aspects of life. It is essential that the Web be accessible in order to provide equal access and equal opportunity to people with diverse abilities. Access to information and communications technologies, including the Web, is defined as a basic human right in the United Nations Convention on the Rights of Persons with Disabilities.
