The 3WC Web Content Accessibility Guidelines 1.0 address a variety of situations where users operate very differently from the norm, including but not limited to disabilities. Special contexts also include using a different operating system, a voice browser, or a small screen. Urging content developers to consider different situations during page design, the guidelines assert that while each design choice is made with a specific situation in mind, it "generally benefits several disability groups and the Web community as a whole." For example, captioning of audio files not just makes audio files accessible to the hearing impaired, but also supports better machine indexing of content and faster searching of content; redundant text/audio/video can support different learning styles, low literacy levels and second-language access.
For a company, accessible Web design means good business. It’s a way to add huge pool of potential customers as well as their relatives, friends and employers.
