Contrary to popular belief, partially sighted people, and even blind people, can access computers and therefore the Internet, using either enlargement software or text-to-speech and Braille display technologies. The Walloon government has decided to place particular emphasis on the accessibility of its websites. Since April 2003, it has adopted a series of measures to make most of the Walloon public websites accessible. Generally speaking, a website is accessible if it can be used and read by all visitors.

Elderly people, people with motor difficulties, blind or partially sighted people, deaf people and the hard of hearing, epileptic people, dyslexic people or those with concentration difficulties, people who use older technology and mobile technologies are all potential visitors to a website. Working on accessibility involves ensuring that the website's programming language, content and the layout of information are compatible with each visitor's browsing tools and techniques.
