Building Web sites that perform well on mobile devices remains a challenge.

摘要

Nicholas C. Zakas The biggest change in Web development over the past few years has been the remarkable rise of mobile computing. Mobile phones used to be extremely limited devices that were best used for making phone calls and sending short text messages. Today's mobile phones are more powerful than the computers that took Apollo 11 to the moon,~(1)~(0) with the ability to send data to and from nearly anywhere. Combine that with 3G and 4G networks for data transfer, and now using the Internet while on the go is faster than my first Internet connection, which featured AOL and a 14.4-kbps dialup modem. Yet despite these powerful advances in mobile computing, the experience of Web browsing on a mobile device is often frustrating. The iPhone opened up the "real" Internet to smartphone users. This was important because developers no longer had to write mobile-specific interfaces in custom languages such as WAP (Wireless Application Protocol). Instead, all existing Web sites and applications worked perfectly on the iPhone. At least that was the idea.
