What's XHTML?

Your webpage is written in HTML (Hypertext Markup Language) to tell a browser what to display on the screen.  This is called the content of your page.  HTML is defined by the world wide web consortium (w3c) who maintain standards for the web.  
All our sites conform to the latest versions of w3c standards.  This ensures that modern browsers will be able to show the site correctly.

As time goes on people make more demands on the control of the page, and new standards are devised to meet this demand.  Our new demand is for a markup language that supports not just computer-based browsers with big screens, but also personal organizers and WAP phones with small screens, and other devices that may not have screens at all.  w3c has defined a new language called XML (extensible markup language) for these applications.  

The new standard version of HTML to be used for web pages intended for display on a PC is called XHTML.
