You can accommodate the multitude of mobile browsing devices several ways. Some designers build separate, mobile versions of their sites (see Figure 12-1). Using server-side programming, these sites detect the type of device you have and deliver a web page customized for that device. An iPhone web surfer, for example, will see the mobile version of a site, which provides a greatly simplified experience: a single-column design with most of the navigation elements removed, but with a prominent search box added.

Of course, not all of us have the time to create two versions of a website, or the technical skills to program a server to detect a visitor’s browser.
