Evaluation, Repair, and Trasformation of Web Pages for Web Content Accessibility. Review of Some Available Tools

This paper deals with the concept of accessibility of Web sites and to people with disabilities. Major problems arise when there is the need of special browers, which understand the standard HTML, but not the extensions introduced by the most used browsers. The WAI (Web Accessibility Initiative) has pursued some guidelines in order to build accessible sites and the new W3C standards are converging towards those guidelines. A review of some of the tools available for testing the Web pages and correcting them with respect to the guidelines for the accessibility is also presented.
