What is accessibility for the web
As you may be aware on December 21, 2000 The Access Board, a US government agency, issued guidelines for accessibility of information technology under section 508 of the Rehabilitation Act. These guidelines require that Federal departments and agencies create web sites and other information technology that is accessible to people with disabilities, such as the blind and the mobility-impaired. This also affects agencies that contract with the Federal government as they are required to follow section 508 rules. These rules came into affect June 21 2001.
Web content accessibility refers to the availability of web-based information to "non-standard access methods" (e.g., wireless devices or text to speech browsers). Persons with disabilities, approximately 10% of all web users, are currently the largest population using such methods.
