Multi-part forms with css

Simon Wilson linked to an improved on a nice multi-part form built with css. It looks great, it’s fast, but I see one other major problem: validation.
For the server to validate the input it must check all the input when the form is completely filled out. The browser can do initial testing using Javascript but that’s not to be relied on.
If I understand the code (and I haven’t tested this myself), if errors in validation occur then the server will have to probably redirect to the anchor for the first page with an error.
I’d like to take a look at this technique myself later..
