Designing a Page for a Wireless device is consequently misleading and in fact, the term 'Page' is not used. Designing for a Wireless device's limited capabilities and non- standard display requires a new approach. First, WML provides limited graphic capabilities in the form of monochrome bitmaps. There is no support for animated GIF's or streaming video. It is just as well.
Wireless devices have very low bandwidth.
No matter how good you think it is, a cell phone user would be likely to get upset if they thought it was taking longer and costing more in phone charges to view your multimedia extravaganza than to watch the latest Spielburg blockbuster. Next, WML replaces a Web Page with the concept of a Deck of Cards. This provides the ability to transfer a common set of information while buffering and displaying it in manageable chunks. I have seen a couple of references that suggest that you can not design for Wireless devices because of these limitations. In fact I think the opposite is true.
