Abstract
With the increase in number of electronic services being delivered through web portals, a lot of emphasis is being given to ensure the quality of web portals in terms of contents and associated design aspects. This has led to studies investigating various requirements of web users and to guidelines for quality enhancement in order to make web portals accessible to all irrespective of one's age, physical challenges, ethnicity, and level of literacy. In this chapter, the authors address the accessibility issues of web portals based on ongoing research. They analyze the accessibility in three levels (i.e., at the levels of authoring tool, web component, and user-agent). The contents of this chapter can throw light on the design aspects of web portals, web browsers, and media players to make them more suitable for users in general.
