Many websites remain inaccessible for people with disabilities, despite the availability of relevant guidelines and tools. This is mainly due to lack of training of Web designers on accessibility technology. This need is addressed, by ESALP, presented in this paper, a web-based application that is meant to be used as a tool to disseminate and teach Web accessibility guidelines and good design practices. The tool adopts an example-based learning approach. First, it exposes people to the accessibility impasses that arise when certain, established guidelines are violated, and then provides concise advice on how to avoid or resolve them. These examples were derived from an in-depth, Web accessibility evaluation study of 50 Greek websites. The results of this study, in agreement to similar studies, also indicated that the accessibility of the Greek Web is rather low. We argue that the presented tool could help in improving the accessibility of websites by increasing awareness, motivating and educating Web development stakeholders on the subject of accessibility.
