Enabling and Optimizing Web Sites for iPhone and iPod touch Nếu bạn quản lý một trang web, bản phát hành của Apple của iPhone và iPod touch giới thiệu một cách hoàn toàn mới tư duy trong việc thiết kế và phát triển của một trang web. Trong quá khứ, bạn có thể thiết kế tối giản, văn bản - phong cách trang tính chỉ cho người dùng điện thoại di động - hoàn toàn hy vọng trang web bình thường Web của bạn được xem chỉ bởi các trình duyệt máy tính để bàn | Enabling and Optimizing Web Sites for iPhone and iPod touch Oh the irony. On the same day that I began writing a chapter on enabling Web sites for iPhone and iPod touch I would realize firsthand the frustration of browsing sites that just don t work with my iPhone. My boys and I were watching the third quarter of a Monday Night Football game when the electricity suddenly went out because of a town-wide outage. Because my son s favorite team was playing he was frantic. What s happening in the game Are the Titans still winning I immediately pulled out my iPhone and confidently launched Mobile Safari in search of answers. But upon going to NFL.com I discovered that its live updating scoreboard is Flash only. I was left with a gray box with a Lego-like block in its place. I then pointed the browser to the official Tennessee Titans site only to discover useless Lego blocks scattered across its front page as well. We then spent the rest of the outage scouring the Web looking for a site to help us. If you manage a Web site Apple s release of iPhone and iPod touch introduce a whole new way of thinking in the design and development of a site. In the past you could design a minimalist text-only style sheet for mobile users fully expecting your normal Web site to be viewed only by desktop browsers. However expectations of iPhone and iPod touch users are not so modest. They are expecting to view the full Web in the palm of their hands. Therefore as you design and develop your Web site you will want to consider the level of support you wish to provide for these Apple devices whether to offer mere compatibility device friendliness or even a design specifically targeting them. This chapter goes over the four tiers of enabling your Web site for Mobile Safari Tier 1 Compatibility Tier 2 Navigation friendliness Tier 3 Device-specific style sheets Tier 4 Dedicated alternative site Chapter 8 Enabling and Optimizing Web Sites for iPhone and iPod touch Tier 1 iPhone iPod touch .
