In this chapter, I discuss the foundational principles and techniques for creating designs for multiple mobile devices. As discussed earlier, the mobile web is the only ubiquitous platform for delivering content to mobile devices. This makes it an incredibly powerful platform in terms of its reach, but like most things in mobile, every blessing comes with a curse. The price for ubiquity is that not all designs are rendered the same.
There are two basic approaches to creating cross-platform mobile designs: content adaptation, in which you create many versions of your site, or no content adaptation, in which you don’t. In either case, you need to have a firm understanding of how to design content for the mobile context. Though I won’t discuss the pros and cons of adapting for devices until Chapter 13, for now it is important to understand that the rendering of many of the standards and techniques I discuss in this chapter are measured on a sliding scale of consistency across multiple devices.
