This blog site is now W3C XHTML and CSS validated. See the badges at the bottom of the page to re-validate.

Note: The CSS validation only validates the main CSS for the blog, not the generated CSS for the iPhone portions, as that gets a bit esoteric in places!

The addresses of the HTML and CSS validators are below, just paste in an internet visible URL and it'll give you feedback on your adherence to standards.
