XHTML5 Example

This example uses XHTML5 markup.

See the source of this example.

Don't forget

• To escape your colons with a backslash

Since this is XHTML5, also don't forget

• That clean code is paramount or you'll get parser errors
• The double namespace declaration in the 'html' element, one for the HTML5 elements and one for the rest
• The UPPERCASE doctype
• The serving as 'application/xhtml+xml' except for IE, since it wants 'text/html'
• The XML declaration that you don't serve to IE, since it can trigger quirks mode

Does this validate?

Yes! See:

• The W3C validator
• The .nu validator
