Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
The browser we'll focus on is Mobile Safari—a WebKit-based browser engine that does an excellent job of parsing HTML5 and interpreting JavaScript.
Note Browsers use different rendering engines. Safari and Google Chrome use WebKit, Opera uses Presto, Firefox uses Gecko, and Internet Explorer uses Trident. In later chapters we'll need to use specific features of WebKit to achieve a more native-looking mobile web application.
Mobile Safari acts and renders in many ways similar to regular Safari, but it has a smaller screen, of course, and responds to gestures and touches as opposed to clicks. It also has noticeable performance differences and does not support Adobe Flash.
One of mobile Safari's most important screens is its Settings screen. You can get to it by clicking on Settings, and then Safari on the iPhone or iPad home screen. You'll see a screen like the one shown in Figure 1-1.
