Example text

Instead, by default a user looks at a web page that has been rendered at a resolution of 980 pixels (with a few exceptions, as we’ll note when talking about web development). In other words, it’s as if users pulled a web browser up on their computer screen that was 980 pixels wide, and then scaled it down by a factor of either 2:1 or 3:1—depending on the orientation of the iPhone—to display at either 480 or 320 pixels wide. ” As you’ll see, viewport size can be set by hand as part of a web page design, forcing a page to scale either more or less when it’s translated onto the iPhone.

It’s a full-fledged desktopgrade browser with access to DOM, CSS, and JavaScript. However, it doesn’t have access to some client-side third-party software that you might consider vital to your web page’s display. The two most-used third-party software packages that aren’t available natively to the iPhone are Flash and Java. There was some discussion of a Java release in 2008, but the SDK’s restriction against downloads seems to have put that effort on hold. We’ll talk about these and other “missing technologies” more in chapter 3.

Recall that the iPhone’s touchscreen is multi-touch. ” The “pinch” zooming of the iPhone is one such example. To zoom into a page, you tap two fingers on a page and then push them apart, while to zoom in you similarly push them together. Finally, the finger is not persistent. A mouse pointer is always on the display, but the same isn’t true for a finger, which can tap here and there without going anywhere in between. As you’ll see, this causes issues with some traditional web techniques that depend on a mouse pointer moving across the screen.
