Pronounced “zool.” Short for Extensible User-Interface Language, a series of XML tags that allow different operating platforms to exchange data that describe a program��s user interface. XUL is designed to ease cross-platform (e.g., Windows, Mac and Linux) interface of applications, which traditionally would have been difficult to customize from one to another.
XUL supports cascading style sheets, JavaSpcript, RDF, DOM and HTML. Since it is an XML language, all features available to XML are also available to XUL. Some of the interface elements that are easily set up using XUL include:
