Of all the recent HTML 5 noise of late, and some pretty flashy webapps to be demoed from them, I got a little concerned that the HTML we know and love was going to turn into some RIA scripting beast. Alas there is not much to be concerned with so far, this little tutorial starts with very small baby steps that people with limited CSS, HTML and JS exposure can appreciate.
Starting with a cool intro on the geolocation feature, then diverting to a javascript library to make code that tests for HTML 5 features more readable, its currently up to a modest part 3, talking about the new input types in the classic form element.
