WML stands for Wireless Markup Language, it is the first markup language standard for wireless devices and similar to HTML in that tags are used to create pages. It supported to all the major mobile phone manufacturers. Newer specifications of WML support XHTML tags, as well as the use of TABLE and FORM tags, although it’s not advocated to use them since they increase file size, thus defeating the purpose of creating lightweight pages. WML is a 'markup' language, means it can be written and saved as text files, using 'tags' like those found in HTML. Who's familiar with HTML should learn WML easily.
