Wireless Markup Language / WML Tutorial
WML (Wireless Markup Language) is the first markup language standard for wireless devices. It is supported by all the major mobile phone manufacturers. At the beginning of this WML tutorial, you can learn about the basics of WML, such as the deck and card concept, WML's document structure and syntax, etc. Then topics like font styles, images, tables, anchor links and softkeys will be covered. After that we will move on to more advanced topics of WML like events, input elements, variables, and the submission of form data to the server. Plenty of code examples are given in the WML tutorial to help you understand the concepts and techniques.
