E-Accessibility

People use the Web in very different ways. A site should therefore present information in a way that people can access information regardless of what kind of hardware or software they are using, and regardless of how they navigate through a site. Criteria that make a website accessible are helpful for all users of a website. The concept behind is "universal design", which improves the way of accessing information for all internet users.

Users with disabilities might need assistive devices to go online. Different disabilities sometimes require similar accommodations: Someone who is blind and someone who cannot use his or her hands both require full keyboard equivalents for mouse commands in browsers and authoring tools, since they both have difficulty using a mouse but can use assistive technologies to activate commands supported by a standard keyboard interface.
