XUL which is pronounced zool stands for XML User Interface Language is a Mark-up language used primarily in Mozilla applications. It allows for the creation of feature rich visually appealing cross platform applications to be easily created and maintained for online or offline use.
XUL is an XML language and thus has the advantages of inserting other XML languages into it such as XHTML, MathML and SVG. Also because of its localized structure it can be easily translated into other languages.
XUL is commonly used for creating feature rich widgets and user-interfaces such as:
* textboxes and inputs * Toolbars and buttons * navigation menus * Tabbed windowing systems * Keyboard Mnunomics and input handling
