XHTML is an XML based markup language based on HTML, designed to have the same capabilities as HTML but also be XML valid.
While most web sites currently use HTML as it is more lenient in its syntax, XHTML has a strong following as well, and some browsers recognize and render the XHTML content type application/xhtml+xml, however notably Microsoft’s IE does not.

XUL is a markup language that defines user interfaces. XUL is a part of the Mozilla project and is as part of Gecko.
HTML or HyperText Markup Language is a language for describing documents, in common use on the world wide web.
HTML is an international standard that is maintaned by the W3C – however officially HTML has been succeeded by the XML compliant format XHTML published by the W3C.
Unofficially, HTML 4.01 is the most popular format in use, and although HTML 4 defines stricter syntactic rules than earlier versions, it is not 100% XML compatible like XHTML.
HTML is complemented by two other web technologies, JavaScript, a language for scripting behaviors in web pages and CSS, a language for describing style of how pages are displayed.
Some HTML elements overlap CSS in defining style, however in good practice it is recommended that HTML elements be restricted to either navigational elements (links) or structural markup that describes the meaning of the text to be displayed. sağlık
Textile is a web text markup-language that balances the strength of HTML with speed and ease of editing.
Unlike many wiki or other markup languages, Textile sticks closely to the semantics of HTML, headings for example are represented by ‘h1’, ‘h2’ for <h1> and <h2>. Attaching classes and ids to elements is also easy with Textile.
Textile is used by both blogs and a number of wikis, including the Ruby on Rails instiki powered wiki and by SWiK. Textile does not make a provision for wiki links however, so various wikis have interpreted their own wiki link standards.
