Detecting HTML 5 is as easy as 1-2-3

To test support for HTML 5 and display different messages based on whether HTML 5 support is available, try this:

1. Create a sample web page. Include a paragraph with a message indicating that HTML 5 is not supported. In the starting <p> tag, include a class attribute with "nohtml". See the example below.
2. Create a style sheet with a template to suppress any HTML tags that have the class="nohtml" attribute. See the style sheet included with the example.
3. Include a xml-stylesheet instruction that references the style sheet.
