What is Accessibility
Accessibility 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.
Following these guidelines will also often make your Web content more usable to users in general.
Understanding accessibility requires an awareness of the special needs of multiple user groups, including people with disabilities and mature users with age-related disabilities. A person with a disability may encounter one or more barriers that can be eliminated or minimized by the software or Web developer, the assistive technology, or the underlying operating system software and hardware platform. The four main categories of disabilities are visual, hearing, mobility, and cognitive.
Accessibility Is More!
It's not about the Disability Discrimination Act 1995 (UK), the Americans with Disabilities Act of 1990 or any other law.
It's not making Websites uglier
It's not that hard

It's about god webdesign.It's about the willingness tp make your website available to everybody.
