Understanding Accessibility

What is Accessible?

Accessible” means usable to a wide range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning difficulties,
cognitive limitations, limited movement, speech difficulties, photosensitivity and combinations of these. Following these guidelines will also make your Web content more accessible to the vast majority of users, including older users.
It will also enable people to access Web content using many different devices – including a wide variety of
assistive technologies.

The Guidelines

W3C Web Content Accessibility Guidelines 2.0 (WCAG) explain how to make Web content accessible to people with disabilities. The guidelines are intended for all
Web content developers (page authors and site designers) and for developers of
authoring tools. The primary goal of these guidelines is to promote accessibility. However, following
them will also make Web content more available to all users, whatever
user agent they are using (e.g., desktop browser, voice browser, mobile phone, automobile-based
personal computer, etc.) or constraints they may be operating under
(e.g., noisy surroundings, under- or over-illuminated rooms, in a hands-free
environment, etc.). Following these guidelines will also help people find
information on the Web more quickly. These guidelines do not discourage content
developers from using images, video, etc., but rather explain how to make
multimedia content more accessible to a wide audience.
