Progressive enhancement is an approach to web development that aims to deliver the best possible experience to the widest possible audience, and simplifies coding and testing as well. Whether users are viewing your sites on an iPhone, the latest and greatest high-end system, or even hearing them on a screen-reader, their experience should be easy to understand and use, and as fully-featured and functional as possible. Designing with Progressive Enhancement will show you how. It’s both a practical guide to understanding the principles and benefits of progressive enhancement, and a detailed exploration of examples that will teach you―whether you’re a designer or a developer―how, where, and when to implement the specific coding and scripting approaches that embody progressive enhancement.
