Evaluation, repair, and transformation of Web pages for Web content accessibility. Review of some available tools

Abstract

This paper deals with the concept of accessibility of Web sites to people with disabilities. Major problems arise when there is the need for special browsers which understand standard HTML, but not the extensions introduced by the most used browsers. The WAI (Web Accessibility Initiative) has pursued 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 Web pages and correcting them with respect to guidelines for accessibility is also presented.
