Welcome to the expanded second edition of Dan Cederholm's best-selling Web Standards Solutions. Web Standards are the standard technology specifications enforced by the World Wide Web Consortium (W3C) to make sure that web designers and browser manufacturers are using the same technology syntax. It is important that these implementations are the same throughout the Web, otherwise it becomes a messy proprietary place, and lacks consistency. These standards also allow content to be more compatible with multiple different viewing devices, such as screen readers for people with vision impairments, cell phones, PDFs, etc. HTML, XML, and CSS are all such technologies. This book is your essential guide to understanding the advantages you can bring to your web pages by implementing web standards and precisely how to apply them. Web standards such as XHTML and CSS are now fairly well-known technologies, and they will likely be familiar to you, the web designer. Indeed, they are all around you on the Web.
