Accessibility is the process of making web content accessible to people with disabilities such as
those who are visually impaired, hearing-impaired, colour blind people, or anyone else who cannot for whatever reason, use a computer in a conventional manner. A website with poor accessibility will be difficult for these people to use. Accessibility is particularly important for sites providing information to those with disabilities such as those in the healthcare sector and government departments. Accessibility is an important aspect to consider when designing any site. Guidelines for the various levels of accessibility are set by industry bodies, such as the W3C WAI.
