WAP CSS / WCSS Tutorial



Preferences - Do not show ads

WCSS (WAP CSS, also known as Wireless CSS or Wireless Profile CSS) is the cascading style sheet language that is used with XHTML MP. It is based on CSS2. Like XHTML MP, WCSS is defined in WAP 2.0.

At the beginning of our WCSS tutorial, we will mention about what WCSS is, the advantages and disadvantages of using WCSS on your WAP site, WCSS's syntax, etc. After that we will look at different ways to apply WCSS cascading style sheets to XHTML MP documents, WCSS selectors, and some of the commonly used WCSS properties. The last part of our WCSS tutorial includes an in depth coverage of the three WAP specific extensions to CSS2 and a brief discussion of how to detect the type of a user agent and apply the appropriate WCSS style sheet to it.
