Designing for WAP applications is really just adapting to a slightly different set of limitations. Writing WML Code WML may be relatively new, but there are already developer resources to help you get started. Many tags are the same, but the format is slightly different. For instance, in WML, all tags must be closed. The optional closing paragraph tag in HTML is required by WML and image tags also have to be closed.
Most Web developers are familiar with HTML editors that simplify Web page coding.
You may be able to write WML using your existing HTML editor. Homesite supports user-defined tags so you can customize it for your WML pages. This seems like the quick and easy option, but remember that the display method for wireless devices is very different from a standard monitor. You may want to simplify your HTML page before you use one of these utilities. Even if you write your WML code strictly by hand, you'll probably use a lot of your existing HTML site because the languages are so similar.
