jQuery’s mobile strategy can be summarized simply: A unified user interface system that works seamlessly across all popular mobile device platforms, built on the rock-solid jQuery and jQuery UI foundation. Focused on a lightweight codebase built on progressive enhancement with a flexible, easily themeable design.
The critical difference with our approach is the wide variety of mobile platforms we’re targeting with jQuery Mobile. We’ve been working hard at bringing jQuery support to all mobile browsers that are sufficiently-capable and have at least a nominal amount of market share. In this way, we’re treating mobile web browsers exactly how we treat desktop web browsers.
