RESS: An Evolution of Responsive Web Design

42,574 views

Published on

Responsive web design has become an important tool for front-end developers as they develop mobile-optimized solutions for clients. Browser-detection has been an important tool for server-side developers for the same task for much longer. Unfortunately, both techniques have certain limitations. I’ll show how both front-end and server-side developers can take advantage of the new technique called RESS (Responsive Web Design with Server Side Components) that aims to be combine the best of both worlds for delivering mobile-optimized content.
