Web Accessibility

Web accessibility means that people with disabilities can use the Web. More specifically, Web accessibility means that people with disabilities can perceive, understand, navigate, and interact with the Web, and that they can contribute to the Web.

W3C Web Accessibility Initiative

Accessibility is not just for people with disabilities

As the quote above suggests, web accessibility is, at its simplest, about ensuring that your content is available to those with disabilities. But web accessibility is about much more than that. Increasingly, more visitors to your site are accessing your content in unique ways. Not every visitor reads your content on-screen in a web browser. Some visitors may not be able to see or hear. Some may not be using computers at all, but may be visiting your site from a number of other types of devices. Some may not even be human. Some of the biggest and, arguably, most important visitors to your site are search engines.

Accessibility means not designing for a particular type of user or device

Because of the multitude of ways in which visitors access and use your content, it is important that you, as a web content author keep the principles of web accessibility in mind when creating content online. When you create content with a specific type of user in mind, you risk making your content inaccessible to countless others. When your design for a specific type of device, your content may or may not work at all on other types.
