The HTML 4 norm provides all required tools to write an accessible code. The advantage of the HTML language is not only that it enables to create a multimedia and hypertext layout of the page. It allows to go further, in providing the text with structural and even semantic information, which can be used by the client software (the browser) according to the user's needs, preferences and possibilities. The — visual — graphical layout is realised with the use of style sheets (Cascading Style Sheets or CSS). The new specifications of HTML (HTML 4.0, April 1998, revised 4.01 August 99) and of CSS (CSS 2, May 1998), help to improve the accessibility of HTML documents in an important way.
