Working with pages is easy with jQuery Mobile: all you really need to know is basic HTML and a few mobile-related attributes. With most of the heavy lifting being done by the framework, it’s easy to focus on the results of the website you’re building. Understanding the internal functionality behind how pages work in jQuery Mobile is what begins to set you up for writing custom functionality. Customizing specific functionality in the messaging and behind the scenes helps to personalize your website. The level of customization that jQuery Mobile provides can be very useful in making a website more user-friendly. Visual indicators, like custom loading messages and page transitions, set expectations for visitors and provide them with a frame of reference, so they know when certain things are happening. Preloading and caching improves usability by speeding up page loads and giving visitors what they want when they want it. jQuery Mobile provides fine-grained control to enhance mobile websites in a custom way.
