What Accessibility?
Accessibility can be considered as "zero property" (a precondition) that characterizes the quality of a website. The concern for universal access to the web was in the mind of Tim Berners-Lee, inventor of the Web, since the beginning of the project in 1989-90, when he worked at CERN, where he presented his proposal for the management of ' information.
What do you mean universal access to the web? Citing
Berners - Lee
Universal access is to make the Web accessible to all by promoting technologies that take into account the vast differences in culture, language training, skills, material resources, access equipment and physical limitations of users on all continents

The web was thus designed to be a universal space of information. Accessibility has as its ultimate goal is to make accessible Web sites and their content to a wider number of browsers, including also the disabled, people with special cognitive problems, people with hardware equipment (such as handheld computers) or software updated (as outdated browser versions). The issue of accessibility is often simplified as "access for the disabled." In reality is more complex web access should be for everyone. For all must be done in such a way that the specificity of the way of access do not constitute an obstacle to relied upon. Millions of people have problems with sensory organs (vision, hearing, touch) until you get to cases of physical and cognitive disabilities and their access to the Internet can really be an insurmountable obstacle. In addition to the human factor, even the technological factor can help make a site inaccessible as the majority of users (60% -70%) have a slow computer and slower and lines (modems are still used more than with speed to 33.6 Kbps or 56 Kbps).
How to make a website accessible?
Some simple examples: I produce the content that I publish the font sizes that can be read by all with ease; I produce content that is not the vehicle information through the use of colors that colorblind people can not distinguish, I produce the content that vehicle information so that the maximum number of people can read it, and then do not use a single language. In this attention to ease of access and therefore the maximum dissemination of the contents, also fit those specific to people accessing the web was not technologically equipped with computers (low-resolution screens, such as 640 x 480, or slow connections, telephone type ) or has physical characteristics which may cause difficulties in navigation (limitations of vision, the ability of motor coordination, etc.).
Lines Driving the "official" for the accessibility of web content, drawn from the Web consortium, which belongs Berners - Lee, have their origin in 1991.
The name of the project: Web Accessibility Initiative (WAI) http://www.w3.org/WAI/
we read the page that the primary goal of the WAI guidelines is to 'explain how to make the Web content accessible to people with disabilities'. These guidelines were drawn up thinking particularly of the developer of web content ('page authors' and 'site designers') and assistive technologies for web browsing.
