HTML5 and CSS3 are becoming the popular language of choice in the web. However, quite like HTML, CSS is prone to errors and difficult to port, so we propose an XML version of CSS that can be used as a standard for creating stylesheets and templates across different platforms and pagination systems. XLaTeX and TeXML are some examples of XML that are close in spirit to TeX that can benefit from such an approach. Modern TeX systems like XeTeX and LuaTeX use simplified \code{fontspec} macros to create style sheets and templates. We use XSLT to create mappings from this XML-style sheet language to \code{fontspec}-based TeX templates and also to CSS3. We also provide user friendly interfaces for the creation of such an XML style sheet.
