Progressive Enhancement in Web Applications

Progressive Enhancement (PE) is an approach for building Web Applications that starts from the perspective that a user browser experience will support a minimum functionality, this is called base line, but has hooks to allow functional enhancements when a browser can support them. PE benefits users by supporting older browsers, but also supporting users with modern browsers and technologies by providing them an improved experience. The progressive enhancement and its counterpart, Graceful Degradation, are approaches that can help rich Web Applications support more browsers and have a wider reach.
