WAP 2.0 supporting XHTML™ MP 1.2
The WAP browser supports the markup languages of WAP 2.0 – XHTML Mobile and XHTML Basic. These two subsets of the Web standard XHTML are supported by all major Web browsers. An XHTML page can be viewed in both the WAP browser and in any standard Web browser. All of the basic XHTML features are supported, including text, images, links, check boxes, radio buttons, text areas, headings, horizontal rules and lists.
In addition to XHTML, the WAP browser supports WML. The user can navigate between WML and XHTML pages. WAP 2.0 also supports cookies, often used by Web sites to store
sheets. By adding a style sheet to the document the developer can control the presentation of the document, the colours, fonts, and layout.
On the Web, the de facto standard style sheet language is Cascading Style Sheets, specified by the W3C and implemented in Internet Explorer, Net- scape, and Opera. For mobile phones, the OMA has identified a subset of CSS and extended it with OMA specific style rules. The CSS subset and the OMA extensions are called Wireless CSS (WCSS).
The WAP browser supports WCSS 1.1.

The presence information is displayed in a contact list.

Cascading Style Sheets (CSS)
Before style sheets were introduced on the Web, developers had little control over the presentation of their Web pages. An XHTML document specifies the structure of the content, which part is a para- graph, which part is a heading, and so on. It does not specify how it shall be presented. Browsers use a default presentation for documents without style
