Overview of this book

Understanding how to create accessible websites is an essential skill these days . You may even be obliged by law to create websites that are usable by the widest audience, including people with a range of disabilities.This book looks at what accessibility is and the various reasons, such as legislative or legal, as to why you really need to understand accessibility and then create websites that can be used by everyone. This book therefore examines the diverse range of user requirements that need to be considered for humans to successfully use web technologies.If you have no experience of being around, or working with, people with disabilities then it can be very difficult to successfully design user interfaces that cover their needs. This book will show you how you can both understand some of the various needs of people with disabilities and the technology they use to interact with computers and the Web.
