The W3C Web Content Accessibility Guidelines (WCAG) provide guidance on making websites accessible to people with disabilities. WCAG 1.0 focused largely on coding requirements that enable websites to interoperate with assistive technologies used by people with disabilities. WCAG 2.0 addresses an environment where website complexity has increased significantly due to higher network bandwidth and the introduction of new interactive technologies. It places more constraints on the default look and feel of a website. Of the 38 Level A and AA provisions, about 50%, impact the website design. This paper reviews those requirements, examining the user needs that they are intended to support and highlighting example strategies for addressing those needs.
