Web Accessibility Initiative (WAI) is an initiative by World Wide Web Consortium (W3C). The main responsibility of the WAI is to work with the global software community to develop and publish guidelines on web accessibility. In 1999 WAI published the first version of the guideline, named Web Content Accessibility Guideline ( WCAG 1.0 ).

In 2008, WAI published the WCAG 2.0, which is the latest version of the guideline. WCAG 2.0 have been widely accepted as the definitive guidelines on how to create accessible websites

WCAG 2.0
WCAG 2.0 organized under 04 main principles and 12 guidelines. Each of these guidelines has testable criteria. It basically covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity and combinations of these.

We need something like this because an estimated of one billion people in the world have some kind of disability. 39 million people are blind in the world and around 246 million people around the world have low vision. More importantly, it is not only for those with disabilities. A fully accessible website is designed to be flexible and responsive to all people.
